Corrected entry: All of the jurors were talking about how the old witness below heard the body hit the floor, and then at that second, feet running toward the door. However, they also mention how the knife was wiped clean. This just doesn't add up. How could the knife be wiped clean when the killer never stopped to wipe it clean?
Corrected entry: In the scene where one juror starts his racist diatribe and all the others leave the table, the man who is the last to change his vote is missing from the room.
Corrected entry: Henry Fonda goes into the jury room humming and harring about making a proper decision and talking it through and so on and so on. Then halfway through the film, talking about the unique switchblade that was crucial to the prosecution's case, he pulls a matching knife out of his pocket and sticks it in the table. If he had a duplicate switchblade all along, why didn't he just show it to the court, or to the jurors as soon as they entered the room?
Corrected entry: The character played by Jack Warden was making a statement about the defendant being a loser, and playing the part of a real baseball fan, uses the statement "He is 5 for 0". He should have said 0 for 5 referring to no hits in five at-bats. The remake of the movie by Showtime corrected this error.
Corrected entry: In the bathroom scene, you can see the guy leave before Fonda does. The door swings like one of those western saloons. Then in the next scene, you can see in the background, Fonda opens the door with the knob, walks out, and closes it.
