Juror #1 / The Foreman
Played By: Martin Balsam (1957), Courtney B. Vance (1997)
The man assigned to moderate the rest of the jury, a job which he is not quite qualified for but determined to do his best at.
- Berserk Button: Whenever someone questions his authority, he'll get all worked up over nothing and suggest to that person they take his place instead.
- Nice Guy: Unless you press his aforementioned Berserk Button, he's a summarily decent guy trying to make the right decisions.
- Race Lift: In the 1997 version.
John Fiedler (1957), Ossie Davis (1997)
"It's hard to put into words. I just think he's guilty. I thought it was obvious from the word, 'Go'. Nobody proved otherwise."
A small, timid banker who mostly gives a "guilty" vote due to pressure from the other jurors.
- Extreme Doormat: He constantly finds himself being swayed by the opinions of the last person who has spoken until, by the end, his courage has visibly grown and he is no longer afraid to stand up to Jurors #3 and #10.
- Nice Guy: He is a really soft spoken guy who tries his best to be nice to even the more belligerent of the jurors.
- Race Lift: In the 1997 version.
Lee J. Cobb (1957), George C. Scott (1997)
"I'm a pretty excitable person. I mean, where does he come off calling me a public avenger, sadist and everything?"
The primary advocate for a "guilty" verdict, whose estrangement from his son causes him to automatically distrust any young person.
- Be Careful What You Wish For: After seeing his son walk away from a fight, he swore to "make a man out of [him]." The last time he and his son saw each other, his son punched him and walked out.
- Big Bad: The closest you can consider one in the film.
- Deadpan Snarker: Part of his jerkass demeanour is that he responds to arguments with deeply sarcastic wisecracks.
- Everyone Has Standards: Like the rest of the jurors, he's disgusted by #10's racism.
- Hair-Trigger Temper / Hot-Blooded: "Excitable? You bet I'm excitable! I'm trying to put a guilty man in the chair where he belongs!"
- Heel Realization: When, in the middle of his furious insistence that the defendant is guilty, he sees the picture of his estranged son and rips it to pieces, you can see in his face that he has just figured out what he was really doing.
- Jerkass: He's aggressive, grump and irritable. It kicks into overdrive as the debate rages on.
- Jerkass Fašade: This just might be his defining characteristic, voting "guilty" simply because of the bad relationship he has with his estranged son, not because of the facts.
- Large Ham: Especially when he's played by George C Scott, who wastes no time in chewing the already-limited scenery.
- Not So Different: From #8; they're both men of passion unwilling to back down when they believe their cause is just.
- Oh, Crap: When he contradicts his own, earlier argument.
- And when the rational part of his brain retakes control as he's tearing up the photo of him and his son, the look on his face changes from rage to absolute horror.
- Red Oni, Blue Oni: The red to Juror #8's blue.
- Villainous Breakdown: His final act in the play before the end and final vote.
Played By: E. G. Marshall (1957), Armin Mueller-Stahl (1997)
A highly methodical and logical man who becomes one of the last holdouts for a "guilty" verdict because the evidence is too strong for him to go against.
- Deadpan Snarker: Known to use this to quip back at some of the apparently less than logical theories.
- Implacable Man
- Ironic Echo: Juror #5 asks him about midway through the film if he ever sweats, to which #4 replies "no." When #8 eventually proves him wrong, #4 begins to sweat.
- Sharp-Dressed Man: He is always in a nice suit but won't take it off even in the heat.
- The Spock: The most logical and rational of the men who voted guilty. When the evidence comes into doubt, he shifts to not guilty.
- The Stoic: One of the few members of the cast to not grow frustrated or angry at the other jurors or the case, always looking at the situation rationally.
- Stoic Spectacles: He wears them and even becomes a plot point.
- Token Good Teammate: Easily the most sympathetic of the three final holdouts, due to voting "guilty" because he really has reached that conclusion through logical thinking rather than the prejudiced views of #3 and #10. The second that the biggest piece of evidence is put into doubt, he changes his vote.
Played By: Jack Klugman (1957), Dorian Harewood (1997)
A man with a similar background to the defendant, who votes "guilty" out of worry that going the other way would simply be due to this.
- Ambiguously Brown: He's hinted to be some kind of minority, despite being played by a white actor (in the first film, at least).
- Berserk Button: Juror #3 gets #5 riled up when he starts accusing him of changing his vote to "not guilty" and insists that since #5 grew up in a slum neighborhood, he's the one to blame. Which makes it pretty awkward when it turns out that #9 was the one who changed his vote.
- Nice Guy: Like The Foreman, unless you push him too far, he is respectful to others.
- Race Lift: In the 1997 version.
- Reverse Grip: His background lets him refute the evidence of the defendant's much taller father having a downward stab wound, something only possible with such a grip, as he knows no experienced switchblade user would do it.
Edward Binns (1957), James Gandolfini (1997)
"Well, I'm not used to supposin'. I'm just a workin' man. My boss does all the supposin', but I'll try one. Supposin' you talk us all out of this, and, uh, the kid really did knife his father? What then?"
A painter who mostly just goes along with the group.
- Berserk Button: He threatens to punch out Juror #3 after the latter repeatedly interrupts #9.
- The Generic Guy: He has the fewest lines of any jury member, and we learn little about him besides his job.
- Nice Guy: He's always polite and reasonable, never making his arguments in a rude way, and makes a point of telling #3 to show #9 a bit of respect, #9 being an elder.
Jack Warden (1957), Tony Danza (1997)
"Well, what's there to talk about? Eleven men in here think he's guilty."
A salesman more concerned with deciding a verdict in time for a baseball game than doing justice.
- Brutal Honesty: He is rarely anything but honest about his feelings.
- Deadpan Snarker: The majority of his dialogue is making wiseass remarks which add little to the proceedings.
- Jerkass: He cares more about missing his baseball game than his job as a juror.
- Nice Hat: Wears a straw fedora throughout the film.
"Nobody has to prove otherwise. The burden of proof is on the prosecution. The defendant doesn't even have to open his mouth. That's in the Constitution."
An architect, and initially the only jury member to vote "not guilty" because he feels the situation needs to be talked over first.
- Establishing Character Moment: First seen pondering at the window of the jury room before being called over to begin the decision. Notably, he isn't shown speaking and chattering excitedly like most of the jurors, hinting that the majority sentiment won't go through as easily as previously thought.
- Guile Hero: Because violence would get him ejected, he must use his mind and instincts to combat the arguments of the others to make them question the evidence enough so there is enough reasonable doubt.
- The Hero: He refused to railroad the defendant because something didn't add up. Despite peer pressure, he continued his stance and pushed to reexamine all the evidence closely.
- Man in White
- Nice Guy: He is a generally nice and concerned man who is focused on ensuring justice is done right.
- The Protagonist: He is the one who gets the others to actually think about the evidence closely.
- Red Oni, Blue Oni: The blue to Juror #3's red.
Played By: Joseph Sweeney (1957), Hume Cronyn (1997)
The oldest of the jury members, whose life experience gives him a unique outlook on the case.
- Awesomeness by Analysis: He has a few key moments of insight which help dismantle the Guilty-voter arguments.
- Cool Old Guy: More so as the movie progresses, which includes taking note of a few small details which the other jurors failed to pick up on.
- The Lancer: He's the first to change to a "not guilty" vote, and spends the rest of the film as #8's biggest supporter, ultimately playing a larger role in poking holes in the biggest piece of evidence.
- Token Good Teammate: Aside from our hero (Juror #8), he is the only one who initially wants to hear more about the case, and doesn't give into Juror #3's tirades about degradation.
Played By: Ed Begley (1957), Mykelti Williamson (1997)
A bigot whose prejudice against Hispanics causes him to be another main antagonist to #8.
- Bowties Are Cool: He dons one as part of his NOI attire in the 1997 version.
- Everyone Has Standards: Is noticeably unimpressed when #3 and #12 are playing a game in the middle of one of the juror's statements.
- Jerk With A Heart Of Jerk: After being left as one of the last three holdouts for a "guilty" vote, he launches into a racist tirade, revealing his true motives behind why he is pushing for a guilty verdict. The other jurors turn away in disgust one by one until he peters out. He never says a word after this and still thinks the defendant is guilty, but changes his vote anyway as he accepts that a conviction is never going to happen now.
- Know When to Fold 'Em: In the remake, he declares the he still thinks the defendant is guilty, but changes his vote anyway as he accepts that a conviction is never going to happen now.
- Malcolm Xerox: In the 1997 version, where Mykelti Williamson plays him as part of a clever little spin on the character.
- Nice Hat: He sports a fez in the 1997 version.
- Perfect Health: Averted: He has a cold and keeps coughing, sneezing and sniffling throughout.
- Race Lift: In the 1997 version, he is portrayed by a black man, (which makes his discrimination to minorities all the more ironic).
- Verbal Tic: "You know what I mean?" (sniff)
- Villainous Breakdown: As is said above he launches into a racist harangue once he is left as one of only three jurors voting "guilty", stating "there is not a one of them[Latinos] that is any good!" He is told to shut up, by one of the other pro-conviction jurors, no less.
Played By: George Voskovec (1957), Edward James Olmos (1997)
A European immigrant and watchmaker who is particularly proud to perform his civic duty as a jury member.
- Immigrant Patriotism: He is proud to be an American and will do his civic duties properly.
- Nice Guy: Like many of the others, he is an affable gentleman but not one to cross or insult their duty in the Jury room.
- "The Reason You Suck" Speech: Gives one to #7 after he changes to a "not guilty" vote simply because it now seems like that will get him out of the room faster.
- Token Minority: In the 1957 version; in the 1997 version half of the cast is African-American while he's European.
Played By: Robert Webber (1957), William Petersen (1997)
An advertising executive who is easily swayed by others.
