Bastards of the Invincibles
Inglourious Basterds, Quentin Tarantino’s 2009 World War II film, contains a few errors. A German soldier wears a uniform that changes from shot to shot in one scene (he is eventually brutally slain with a baseball bat).
The symbol in his pocket, in particular, vanishes and reappears in his scenes. Taking so many distinct parts of different takes must have been a nightmare of a post-production trimming job. The moral of the story is to keep things simple.
