Revealing mistake: Midway through the movie, there is a long-shot of several characters walking outside between two gutted factory buildings. The camera pulls back, zeros in on the base of a huge chimney and pans upward to the very top - where two men in black and white checkerboard jackets are working.
Revealing mistake: At the end of the movie, where Sgt. Eversman talks to the dead Corporal Jamie Smith about Blackburn, he says he's gonna talk to Smith's parents when he gets home. When Eversman places his hand on the chest of Smith, you can see his eyelids move. (02:14:08)
Revealing mistake: When Vercingétorix leaves the Romans to go to Gergovia there is a stone mason by the road carving what is probably a distance marker. The man's chisel is obviously not in contact with the stone - while he is banging it with the hammer it is waving around in the air. (00:17:00)
