Continuity mistake: In one scene, some of Saddam's troops pour oil all over Mark Whalberg's face (while forcing him to bite down on a CD so it runs into his mouth) in an attempt to torture him. The next scene, when he is rescued, he has nothing but the requisite smudges and "movie dirt" on his face. Apparently the Iraqis decided to clean the oil slick off of his face before he got rescued.
Continuity mistake: In the caning scene two different canes are used, look at the tip. (01:38:45)
Continuity mistake: When the Austrian Emperor and Gustav's father die on the same day Gustav puts their photographs on a sideboard. The close-up of Gustav's father's picture shows a white background, in contrast to all wide shots. (00:44:15)
Continuity mistake: When Joan first meets with her captains in Orleans, they argue. She walks away and La Hire calls her "a helluva woman". As she walks away, you can see him looking at her. Immediately, she turns back, and he is now looking at the other captains as she walks up to him and belts him. He must have turned his head very quickly, too quickly to be caught on film.
Continuity mistake: At one point when Nick and George are driving the the Porsche, their seat-belts alternate between being on and off between shots.
