Revealing mistake: About 3/4 through the movie, Bradley Cooper and his wife are talking in a bedroom or nursery. He takes his daughter and holds her - the baby is clearly fake.
Continuity mistake: A brave captive is dragged to Artemisia who is eating an apple. It alternates between being green or red throughout the scene. (00:21:35)
Other mistake: The credits list "Young SS Trouper" instead of "Trooper." (02:03:30)
Continuity mistake: When fuelling up the tank, Claudette can be seen with her hand on her head leaning against the hull of the tank. Camera changes and now she is stood and doesn't have her hand on her head. (00:11:20)
