Corrected entry: Eli Wallach's character states a number of times he has 40 men. Assuming he is in addition to that, there should be 41, yet we see at least 44 die on screen. That does not count the ones shot at inside buildings when McQueen or Buchholz go charging through, or the one behind the window when McQueen is shot, or the ones that escape and ride away. This includes the 3 that spy on the town, 12 in the first shootout, and 29 in the big finale fight.
Corrected entry: When the first gunfight begins, everyone dives for cover while firing but Brynner is the only one who stands his ground and fires. Yet, in such an exposed position, none of the bandits shot him.
Corrected entry: When Brynner and McQueen are riding the funeral hearse and someone fires a gun at Brynner from a nearby building window, at first there's no noticeable change. Then, in the very next shot, Brynner's cigar is suddenly wrecked, supposedly from that single shot.
Corrected entry: I find it very strange that none of the bandits recognized Buchholz when he went "undercover" and posed as one of them. They saw his face, he even spoke a few words, so why didn't they see at once that he was not one of them?
