Mallett, J.
We granted leave in this case1 to determine whether the Court of Appeals erred in granting the defendants, Vester Mills and James Camilli, a new trial on the basis that seventeen color slides shown to their juries, that depicted the victim’s severe burn wounds over more than sixty percent of her body, were unfairly prejudicial. In addition, only with respect to defendant Mills, we granted leave to determine whether the Court of Appeals erred in granting him a new trial on the ground that his jury should have been instructed on the defenses of "accident” and "intoxication.”
We reverse the decision of the Court of Appeals on both issues and reinstate the defendants’ convictions.

On the night of June 23, 1989, defendants, Ves[64]*64ter Mills and James Camilli,2 drove to a low-income housing project to locate Camilli’s girlfriend, who he believed was visiting another man at the complex. While seated in their car at the complex, the defendants engaged in a heated debate with a group of men, reputed drug dealers, who apparently approached and stood outside the vehicle. Some exchanges were made and the men outside the vehicle smashed most of its windows with baseball bats. In an apparent attempt to seek retribution, the defendants drove to a service station where one of them filled an empty soda bottle with a few cents worth of gasoline.
On the defendants’ drive back to the housing project, they encountered Kristen Grauman, a nineteen-year-old woman. Mr¡ Camilli asked her whether she knew where he could buy a rock of cocaine. Promising to provide directions, Ms. Grauman entered the back seat of the car, driven by Mr. Camilli with Mr. Mills occupying the front passenger seat. Grauman became frightened when Mr. Camilli ignored her directions and Mr. Mills encouraged him to "[k]eep going.” Grauman panicked and tried to escape through the back window on the driver’s side, but Mr. Mills grabbed her by the right leg and would not let her go.
Ms. Grauman then felt something cold and wet all over her body, and saw Mr. Mills dumping or throwing something toward her from the front passenger seat as he held her leg. The next thing Ms. Grauman saw was a small flame coming toward her and then suddenly, she realized that she was on fire.
She then fell or was pushed from the window of the car and landed on the street. Her attempt to [65]*65extinguish herself by rolling on the ground was unsuccessful. She eventually ran toward a ditch and heard a loud "hiss.” Fortunately, the ditch was filled with water, which extinguished the fire. She did not recall much more about the incident. Ms. Grauman suffered severe burns over sixty percent of her body, as well as severe inhalation injury.
Mills and Camilli were charged with assault with intent to commit murder in connection with the severe burning of Ms. Grauman. MCL 750.83; MSA 28.278. They were tried jointly, but with separate juries. Each defendant was convicted by a jury of assault with intent to commit murder, and each was sentenced to a term of life imprisonment.
The Court of Appeals reversed the convictions of both defendants and remanded for a new trial, holding that the trial judge erred in admitting seventeen slides of the burned victim into evidence. "The probative value to be gained from projecting full-color slides of subsequent medical treatment, including extensive surgical intervention, was clearly outweighed by the danger of unfair prejudice. MRE 403.” Unpublished opinion per curiam, issued June 9, 1994 (Docket Nos. 130332 and 130333), slip op at 1. The Court of Appeals felt that "[tjhere was a clear danger that replicating so many gruesome slides would encourage the jury to abdicate its truth-finding function based on sympathy and passion.” Id., citing People v Coddington, 188 Mich App 584, 598; 470 NW2d 478 (1991).
Further, the Court of Appeals held, with respect to Mr. Mills, that the trial judge erred in not instructing the jury on the defenses of "accident” and "intoxication.” The Court of Appeals opined that both instructions were adequately supported [66]*66by circumstantial evidence. Id., citing People v Hoskins, 403 Mich 95, 100; 267 NW2d 417 (1978).3

The first question we must answer is whether the seventeen slides depicting the burned victim were admissible at trial under the Michigan Rules of Evidence. We must first determine whether the evidence is relevant under MRE 401. Second, if the evidence is relevant, we next determine whether the evidence should be excluded under MRE 403, whether the probative value of the evidence is substantially outweighed by the danger of unfair prejudice.
a. relevancy: mre 401
Pursuant to MRE 401, " 'Relevant evidence’ means evidence having any tendency to make the [67]*67existence of any fact that is of consequence to the determination of the actions more probable or less probable than it would be without the evidence.” (Emphasis provided.) There are two separate questions this Court must answer to determine whether the evidence was admissible under MRE 401.4 First, we must determine the "materiality” of the evidence. In other words, we must determine whether the evidence was of consequence to the determination of the action. Second, we must determine the "probative force” of the evidence, or rather, whether the evidence makes a fact of consequence more or less probable than it would be without the evidence. 1 McCormick, Evidence (4th ed), § 185, p 773.
Materiality, under Rule 401, is the requirement that the proffered evidence be related to "any fact that is of consequence” to the action. "In other words, is the fact to be proven truly in issue?” Wade & Strom, Michigan Courtroom Evidence (rev ed), Rule 401, p 71. A fact that is "of consequence” to the action is a material fact. People v McKinney, 410 Mich 413, 418-419; 301 NW2d 824 (1981). "Materiality looks to the relation between the propositions for which the evidence is offered, and the issues in the case. If the evidence is offered to help prove a proposition which is not a matter in issue, the evidence is immaterial.” McCormick, supra, § 185, p 773.
However, materiality does not mean that the [68]*68evidence must be directed at an element of a crime or an applicable defense. 1 Weinstein & Berger, Evidence, ¶¶ 401[01] to 401[03], pp 401-7 to 401-26. (See also comments to FRE 401, which is identical to MRE 401.) As stated by the United States Court of Appeals for the Sixth Circuit, in United States v Dunn, 805 F2d 1275 (CA 6, 1986), a material fact "need not be an element of a crime or cause of action or defense but it must, at least, be 'in issue’ in the sense that it is within the range of litigated matters in controversy:” Id. at 1281. See also Weinstein & Berger, supra, ¶ 401[03], p 401-20.
In addition to determining the materiality of the evidence, we must also consider the principle of probative force. Probative force is the "tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.” Further, "any” tendency is sufficient probative force.

The first question we must answer is whether the seventeen slides depicting the burned victim were admissible at trial under the Michigan Rules of Evidence. We must first determine whether the evidence is relevant under MRE 401. Second, if the evidence is relevant, we next determine whether the evidence should be excluded under MRE 403, whether the probative value of the evidence is substantially outweighed by the danger of unfair prejudice.
a. relevancy: mre 401
Pursuant to MRE 401, " 'Relevant evidence’ means evidence having any tendency to make the [67]*67existence of any fact that is of consequence to the determination of the actions more probable or less probable than it would be without the evidence.” (Emphasis provided.) There are two separate questions this Court must answer to determine whether the evidence was admissible under MRE 401.4 First, we must determine the "materiality” of the evidence. In other words, we must determine whether the evidence was of consequence to the determination of the action. Second, we must determine the "probative force” of the evidence, or rather, whether the evidence makes a fact of consequence more or less probable than it would be without the evidence. 1 McCormick, Evidence (4th ed), § 185, p 773.
Materiality, under Rule 401, is the requirement that the proffered evidence be related to "any fact that is of consequence” to the action. "In other words, is the fact to be proven truly in issue?” Wade & Strom, Michigan Courtroom Evidence (rev ed), Rule 401, p 71. A fact that is "of consequence” to the action is a material fact. People v McKinney, 410 Mich 413, 418-419; 301 NW2d 824 (1981). "Materiality looks to the relation between the propositions for which the evidence is offered, and the issues in the case. If the evidence is offered to help prove a proposition which is not a matter in issue, the evidence is immaterial.” McCormick, supra, § 185, p 773.
However, materiality does not mean that the [68]*68evidence must be directed at an element of a crime or an applicable defense. 1 Weinstein & Berger, Evidence, ¶¶ 401[01] to 401[03], pp 401-7 to 401-26. (See also comments to FRE 401, which is identical to MRE 401.) As stated by the United States Court of Appeals for the Sixth Circuit, in United States v Dunn, 805 F2d 1275 (CA 6, 1986), a material fact "need not be an element of a crime or cause of action or defense but it must, at least, be 'in issue’ in the sense that it is within the range of litigated matters in controversy:” Id. at 1281. See also Weinstein & Berger, supra, ¶ 401[03], p 401-20.
In addition to determining the materiality of the evidence, we must also consider the principle of probative force. Probative force is the "tendency to make the existence of any fact that is of consequence to the determination of the action more probable or less probable than it would be without the evidence.” Further, "any” tendency is sufficient probative force. MRE 401. This definition is well established in Michigan jurisprudence. See Beaubien v Cicotte, 12 Mich 459, 484 (1864), and Collins v Beecher, 45 Mich 436, 438; 8 NW 97 (1881).
Thus, in this case, we must determine if the debated evidence, the seventeen photographs of Ms. Grauman, were evidence of "any fact that is of consequence to the determination” of the defendant’s guilt and whether the photographs made the existence of certain facts more or less probable. We hold that the photographs were proof of many facts that were of consequence to this case and had significant probative force in proving the defendants’ guilt.
The assistant prosecutor delineated seven reasons for seeking admission of the seventeen photographs:
1. The nature and extent of the injuries were [69]*69relevant to the charge of assault with intent to kill because they showed an intent to kill;
2. The photographs showed some splattering, which corroborated the fact that gasoline was thrown on Ms. Grauman;
3. The photograph showed that Ms. Grauman’s right side was more seriously burned than her left side, which corroborated her expected testimony;
4. Each photograph showed a different part of her body so the jury could fully comprehend the nature of the injuries;
5. Dr. Garner testified that the photographic documentation was necessary to show how the injuries evolved and to allow the jury to appreciate the extent of the injuries because the initial photographs did not portray the true injuries to a layperson and would therefore be misleading;
6. The jury was entitled to a basis for Dr. Garner’s opinion concerning the nature and extent of the burns because it did not have to believe the bare testimony; and
7. The photographs demonstrated Ms. Grauman’s state of mind, which Mr. Baker expected to become relevant during cross-examination with regard to inconsistent statements.
We find that these reasons are more than sufficient to prove that the photographs were important to understanding facts that were "of consequence to the determination” of the defendants’ guilt. Specifically, these reasons affect two material facts: (1) elements of the crime, and (2) the credibility of witnesses.
It is well established in Michigan, as well as in most jurisdictions, that all elements of a criminal offense are "in issue” when a defendant enters a plea of not guilty. People v White, 81 Mich App 335; 265 NW2d 139 (1978). The prosecution must [70]*70carry the burden of proving every element beyond a reasonable doubt, regardless of whether the defendant specifically disputes or offers to stipulate5 any of the elements.6 People v Gant, 48 Mich App 5; 209 NW2d 874 (1973). See, e.g., Estelle v [71]*71McGuire, 502 US 62, 69; 112 S Ct 475; 116 L Ed 2d 385 (1991). See also McCormick, supra, § 185, pp 773-785. The elements of the offense are always at issue. Thus, the prosecution may offer all relevant evidence, subject to MRE 403, on every element. The claim that evidence that goes to an undisputed point is inadmissible has also been rejected in criminal cases. See People v Neaton, 294 Mich 134; 292 NW2d 589 (1940), and People v MacPherson, 323 Mich 438; 35 NW2d 376 (1949).
In the instant case, the intent of the defendants was a direct issue because it was an element of the charged offense, intent to commit murder. MCL 750.83; MSA 28.278 provides that "[a]ny person who shall assault another with intent to commit the crime of murder, shall be guilty of a felony, punishable by imprisonment in the state prison for life or any number of years.” Further, it has been held that evidence of injury is admissible to show intent to kill. People v Anderson, 389 Mich 155; 205 NW2d 461 (1973). Thus, one of the crucial elements of the crime and a crucial issue of this case was the intent of Mr. Mills and Mr. Camilli.
The photographs were essential in proving intent because they illustrated the nature and extent of the injuries. The severity and the vastness of the victim’s injuries were of consequence to the determination whether the defendants’ acts were intentional. The fact that the victim was burned over sixty percent of her body made it more probable that the acts of the defendants were intentional and not accidental. It would have been quite difficult to "spill” gasoline on a victim in the back seat of a car that could have caused such severe damage.
Indeed, the photographs were effective in showing "splattered” burns, which were of consequence to the method by which Ms. Grauman was doused [72]*72with the gasoline, i.e., intentionally or accidentally. The splattering made it more probable that the gasoline was intentionally thrown on Ms. Grauman. Had the gasoline been spilled on the victim, the burns would not have been as "splattered.”
Critical to the instant case and a fact that is also "of consequence” to a determination is the credibility of the witnesses, offering testimony. "[MJatters in the range of dispute may extend somewhat beyond the issues defined in the pleadings .... [TJhe parties may draw in dispute the credibility of the witnesses and, within limits, produce evidence assailing and supporting their credibility.” McCormick, supra, § 185, pp 773-774. As noted in Weinstein & Berger, supra, ¶ 401[05], p 401-29, evidence may be admitted to assist in the evaluation of "the credibility of a witness.” Here, the test is "whether the evidence will aid the court or jury in determining the probative value of other evidence offered to affect the probability of the existence of a consequential fact." Id. (emphasis provided).
If a witness is offering relevant testimony, whether that witness is truthfully and accurately testifying is itself relevant because it affects the probability of the existence of a consequential fact.7 In the instant case, the credibility of both the victim and the prosecution’s expert, Dr. Garner, was directly at issue and was "of consequence” to the determination of the case. The jury was entitled to view the nature and extent of the injuries [73]*73for itself, and not to depend solely on the testimony of the experts. Dr. Garner, the prosecution’s expert witness, testified that the photographs were necessary to show how the injuries occurred. He explained that he could not adequately convey the severity and life-threatening quality of the injuries to laypersons without the aid of the pictures.8 Because the photographs were illustrative of the injuries, they consequently assisted the jury in determining the credibility of Dr. Garner.9 In addition, the photographs, which illustrated that Ms. Grauman’s injuries were much more severe on her right side, than her left, corroborated her testimony that Mr. Mills, who sat in the passenger’s seat, held on to her right leg and threw the gasoline on her while she attempted to escape through the left side of the vehicle.10 Even the trial [74]*74court was cognizant that Ms. Grauman’s credibility was at issue:
I’m also very mindful of the fact that [Ms. Grauman’s] credibility is an issue in the case. I was not aware during the course of some of the pre-trial hearings of the extent of her injuries because like any layman thinking in terms of burns that are treated with gauze and ice cubes.
In thinking in terms of severe as those that Ms. Grauman had I also was not aware of fact as to just how much morphine is required to sedate a burn victim so that the level of pain is kept as low as possible. I was not aware they could never get rid of the pain with the use of morphine.
That being the situation, it becomes very clear to me that the jury just hearing the testimony may have absolutely no comprehension of all the procedures that the individual that’s being treated had to go-through and why they may give answers that seem inconsistent with an average individual in the hospital would give.
Likewise, the photographs helped to demonstrate Ms. Grauman’s state of mind, which the assistant prosecutor expected to become relevant during cross-examination. Ms. Grauman had been through great pain and suffering, and the photographs assisted the jury in understanding her horrific ordeal and her state of mind.
B. PROBATIVE v PREJUDICIAL: MRE 403
Having decided that the photographs are relevant under MRE 401, the next question is whether the evidence must be excluded under MRE 403. [75]*75Pursuant to MRE 403, "Although relevant, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, or by considerations of undue delay, waste of time, or needless presentation of cumulative evidence.”
All evidence offered by the parties is "prejudicial” to some extent, but the fear of prejudice does not generally render the evidence inadmissible. It is only when the probative value is substantially outweighed by the danger of unfair prejudice that evidence is excluded.
Relevant evidence is inherently prejudicial; but it is only unfair prejudice, substantially outweighing probative value, which permits exclusion of relevant matter under Rule 403. ... Its major function is limited to excluding matter of scant or cumulative probative force, dragged in by the heels for the sake of its prejudicial effect. ... It is not designed to permit the court to "even out” the weight of the evidence, to mitigate a crime, or to make a contest where there is little or none. [United States v McRae, 593 F2d 700, 707 (CA 5, 1979).]
Similarly, the Michigan Court of Appeals stated:
"Unfair prejudice” does not mean "damaging.” Bradbury v Ford Motor Co, 123 Mich App 179, 185; 333 NW2d 214 (1983). Any relevant testimony will be damaging to some extent. We believe that the notion of "unfair prejudice” encompasses two concepts. First, the idea of prejudice denotes a situation in which there exists a danger that marginally probative evidence will be given undue or pre-emptive weight by the jury. In other words, where a probability exists that evidence which is minimally damaging in logic will be weighed by the jurors substantially out of proportion to its [76]*76logically damaging effect, a situation arises in which the danger of "prejudice” exists. Second, the idea of unfairness embodies the further proposition that it would be inequitable to allow the proponent of the evidence to use it. Where a substantial danger of prejudice exists from the admission of particular evidence, unfairness will usually, but not invariably, exist. Unfairness might not exist where, for instance, the critical evidence supporting a party’s position on a key issue raises the danger of prejudice within the meaning of MRE 403 as we have defined this term but the proponent of this evidence has no less prejudicial means by which the substance of this evidence can be admitted. [Sclafani v Peter S Cusimano, Inc, 130 Mich App 728, 735-736; 344 NW2d 347 (1983).]
The decision to admit or exclude photographs is within the sole discretion of the trial court. Melynchenko v Clay, 152 Mich App 193; 393 NW2d 589 (1986); People v Gregory, 21 Mich App 76; 174 NW2d 905 (1969); People v Dejarnette, 97 Mich App 488; 296 NW2d 81 (1980). Photographs are not excludable simply because a witness can orally testify about the information contained in the photographs. People v Eddington, 387 Mich 551; 198 NW2d 297 (1972); People v Falkner, 389 Mich 682; 209 NW2d 193 (1973); People v Terlisner, 96 Mich App 423; 292 NW2d 223 (1980); People v. Sullivan, 97 Mich App 488; 296 NW2d 81 (1980). Photographs may also be used to corroborate a witness’ testimony. People v Jones, 24 Mich App 702; 180 NW2d 818 (1970). Gruesomeness alone need not cause exclusion. People v Myers, 30 Mich App 409; 186 NW2d 381 (1971); People v Alexander, 104 Mich App 545; 305 NW2d 262 (1981). The proper inquiry is always whether the probative value of the photographs is substantially outweighed by unfair prejudice.
[77]*77In Eddington, 387 Mich 562-563, this Court stated:
"Photographs that are merely calculated to arouse the sympathies or prejudices of the jury are properly excluded, particularly if they are not substantially necessary or instructive to show material facts or conditions. If photographs which disclose the gruesome aspects of an accident or a crime are not pertinent, relevant, competent, or material on any issue in the case and serve the purpose solely of inflaming the minds of the jurors and prejudicing them against the accused, they should not be admitted in evidence. However, if photographs are otherwise admissible for a proper purpose, they are not rendered inadmissible merely because they bring vividly to the jurors the details of a gruesome or shocking accident or crime, even though they may tend to arouse the passion or prejudice of the jurors. Generally, also, the fact that a photograph is more effective than on oral description, and to the extent calculated to excite passion and prejudice, does not render it inadmissible in evidence.” [Quoting 29 Am Jur 2d, Evidence, § 787, pp 860-861.][11]
In the instant case, the relevancy of the photographs was not substantially outweighed by the danger of unfair prejudice. The photographs are accurate factual representations of the injuries suffered by Kristen Grauman and the harm the defendants caused her. The photographs did not present an enhanced or altered representation of [78]*78the injuries. Although the photographs are graphic, their probative value was not substantially outweighed by their possible prejudice.
As discussed above, the photographs were probative because they made it more probable that the defendants intentionally set Ms. Grauman on fire. For example, the photographs depicted greater burns on Ms. Grauman’s right side in comparison to her left.12 Also, the photographs illustrated the "splattering” of burns that are indicative that gasoline was thrown, not spilled, on the victim. Lastly, the photographs were helpful in corroborating the evidence of the prosecution’s expert and Ms. Grauman.
The probative force was not substantially outweighed by the danger of unfair prejudice. The court viewed approximately 30 out of the 150 slides, and ultimately admitted seventeen. We are satisfied that the trial court admitted only those photographs that were necessary in furthering the probative force, and omitted those that were repetitive or too gruesome and unfairly prejudicial.
We are satisfied that the trial court carefully and properly reviewed the slides. The trial court [79]*79excluded those that appeared to be too painful. For example, the trial judge ruled out photograph number 105 because it looked too painful.
The Court: With regard to the photographs, I gave a great deal of thought to the admission of the various photographs, and I considered the doctor’s testimony at the separate record hearing quite a bit in terms of making a determination as to what I would allow and what I would not allow.
Photograph 105, although the doctor said she was healing at this point, as Mr. McGuire has correctly indicated, the doctor is talking about one thing and we’re talking about something completely different. The photograph to me happens to be a photograph of someone that if she is not, should be in a great deal of pain because she looks a bright red from the middle of her face all the way down to the point where you can see on that photograph. Because the photograph looks so painful, I was of the opinion that there were other photographs that could accurately depict the extent of the injuries.
We find that the trial court properly allowed the jury to view the relevant evidence, without admitting evidence that was unfairly prejudicial. It was important for the jury to know the extent and nature of the injury suffered by the victim. Although we must protect the defendant from the prosecution’s attempt to shock the jury, we must also make sure that the truth is found through relevant evidence that is not unfairly prejudicial.
The trial court is not expected to protect the jury from all evidence that is somewhat difficult to view. The Rules of Evidence provide that the court must only limit that evidence whose probative value is substantially outweighed by the danger of unfair prejudice. MRE 403. In this case, the pictures were gruesome; however, they were neces[80]*80sary to the proper determination of the defendant’s guilt and were not unfairly prejudicial.
On this record, we find that the photographs were properly admitted by the trial court because they were necessary to show the defendants’ intent to kill and to corroborate the testimony of the prosecution’s expert and Ms. Grauman. The Court of Appeals failed to recognize the important probative force of this evidence and improperly found that the probative value was substantially outweighed by the danger of unfair prejudice. For these reasons, we reverse the Court of Appeals decision and reinstate the defendants’ convictions.

Pursuant to MCL 768.29; MSA 28.1052, the trial court is required to instruct the jury concerning the law applicable to the case and fully and fairly present the case to the jury in an understandable manner. People v Moore, 189 Mich App 315; 472 NW2d 1 (1991). MCL 768.29; MSA 28.1052 provides:
It shall be the duty of the judge to control all proceedings during the trial, and to limit the introduction of evidence and the argument of counsel to relevant and material matters, with a view to the expeditious and effective ascertainment of the truth regarding the matters involved. The court shall instruct the jury as to the law applicable to the case and in his charge make such comment on the evidence, the testimony and character of any witnesses, as in his opinion the interest of justice may require. The failure of the court to instruct on any point of law shall not be ground for setting aside the verdict of the jury unless such instruction is requested by the accused.
A criminal defendant has the right to have a [81]*81properly instructed jury consider the evidence against him. People v Vaughn, 447 Mich 217; 524 NW2d 217 (1994); People v Lewis, 91 Mich App 542; 283 NW2d 790 (1979). However, a trial court is not required to present an instruction of the defendant’s theory to the jury unless the defendant makes such a request. People v Wilson, 122 Mich App 1, 3; 329 NW2d 513 (1982). Further, when a jury instruction is requested on any theories or defenses and is supported by evidence, it must be given to the jury by the trial judge.13 People v Rone (On Remand), 101 Mich App 811; 300 NW2d 705 (1980). A trial court is required to give a requested instruction, except where the theory is not supported by evidence. People v Stubbs, 99 Mich App 643; 298 NW2d 612 (1980); People v Staph, 155 Mich App 491; 400 NW2d 656 (1986).14
In the instant case, defendant Mills asked for an accident instruction, CJI 17:1:03, which provides: [82]*82"Purpose to Injure is Necessary—Injury Cannot Occur Accidently. An assault . . . cannot occur accidently or thoughtlessly.” The trial court held that "[tjhere isn’t any evidence in this case that supports the notion that there was any accident involved in this case. . . . [T]here is nothing that remotely approaches the notion of car[e]lessness or thoughtlessness and that being the situation, I’ll not give the instruction.”
We similarly find that the record is devoid of any evidence supporting a jury instruction of accident.15 The defense did not introduce any evidence that the gasoline w;as accidentally or inadvertently spilled on Ms. Grauman. There was only evidence that the defendants threw or dumped the gasoline on Ms. Grauman while she tried to escape out the back window. Further, there was no evidence that the cigarette lighter was accidentally lit at the same time as the gasoline spilled. To say that Ms. Grauman was set on fire by a series of accidents is to go against basic logic.
Likewise, there was no evidence that supported the instruction of intoxication. A defense of intoxication is only proper if the facts of the case could allow the jury to conclude that the defendant’s intoxication was so great that the defendant was unable to form the necessary intent. People v Savoie, 419 Mich 118; 349 NW2d 139 (1984). In the instant case, there was some evidence that the defendants appeared intoxicated, but there was no testimony that the defendant actually was intoxicated, or was intoxicated to a point at which he [83]*83was incapable of forming the intent to commit the charged crime.
For example, Margaret Velasquez testified that she saw the defendants about midnight on June 24, 1989. She witnessed a tannish-colored Chevette with broken windows enter the gas station. Both men were loud and obnoxious. In addition, Patsy Whitlow, an employee of the gas station, described the man who came into the store as being in a hurry, nervous, and appeared "high.” Despite this testimony, the trial court ruled that there was nothing in the record to show that Mills had consumed anything that night.
Under the circumstances, there is absolutely nothing on this record to substantiate the notion that Mr. Mills had consumed anything that night. People can appear one way to someone else when in actuality there is something else causing them to act the way they are being observed. Under the circumstances, I don’t think the intoxication instruction is supported by anything that I’ve heard on this record ....
We agree. Other than appearing high of drunk, there is no indication on the record that defendant was drunk or high on drugs and was incapable of forming the intent to commit this, crime. With evidence that Mills was able to grab Ms. Grauman by the right leg, and at the same time was able to dump or throw gasoline on her, we cannot find that Mr. Mills was intoxicated, or intoxicated to the point at which he was incapable of forming the intent to commit the crime. We hold that the trial court properly denied the request to instruct on this defense. Accordingly, we reinstate defendant Mills’ conviction.
[84]*84CONCLUSION
We hold that the Court of Appeals erred in granting defendants Mills and Camilli a new trial on the basis that seventeen color slides shown to their juries, that depicted the victim’s severe burn wounds over more than sixty percent of her body, were unfairly prejudicial. We find that the probative force of the photographs was not substantially outweighed by the danger of unfair prejudice. In addition, with regard to defendant Mills, we hold that the Court of Appeals erred in granting Mills a new trial on the ground that his jury should have been instructed on the defenses of "accident” and "intoxication.” There was insufficient evidence on the record to support either of these instructions.
We reverse the decision of the Court of Appeals on both issues and reinstate the defendants’ convictions.
People v Mills, is remanded to the Court of Appeals for consideration of the remaining issues raised in that Court by the defendant.
