Continuity mistake: Just after they have loaded up the truck with the gold, Amir's wife is shot. When he runs over to meet his daughter at her mother's side he puts his arms around her, but in the next shot his hands are behind the little girl. There was no time for him to move them. (00:39:15)
Revealing mistake: When the castle is being attacked, Ice Cube dives away from an explosion. If you watch it in slow motion, you can see it's his stunt double. (01:22:50)
Factual error: The Iraqi gunship helicopter attacking the group at the castle is an MD 500 Defender. However, Iraq has never owned or operated these helicopters.
Continuity mistake: When George Clooney is pointing his pistol at a guard in the bunker, the hammer is already cocked back (single action), but in the next shot, the hammer is down (double action) and he cocks it again.
Factual error: When Gates, Barlow, Elgin, and Vig are leaving the village after the milk truck explosion, they give the people MREs. However, the MREs they are passing out are 1996 designed packages. From 1981 until 1995, MREs had a dark brown bag while ones produced from 1996 and current are tan.
Revealing mistake: After Conrad dies, Mark Wahlberg weeps while Conrad is still visibly breathing. (01:34:05)
Factual error: The movie is supposed to be set in central and southern Iraq. At one point, the men are driving along in a Humvee north of Nasiriyah towards Karbala, just south west of Baghdad. Throughout this section of the film, mountains can be seen on the horizon. The actual desert of Iraq is so flat it might as well be a parking lot. The only actual geographic features of the terrain are agricultural berms, which those mountains aren't.
