Audio problem: When the head of the Nazi forced labor camp is on his balcony shooting workers that aren't working, he fires two shots, kills two workers then reloads for a third shot but doesn't shoot. When he goes back inside, he ejects the live round he chambered onto his girlfriend, but when the round hits the floor, it clanks like an empty shell.
Audio problem: The original audio track for the saloon scene towards the end was accidentally lost during filming. Because the film was largely ad-libbed, not all of the lines could be recalled when the scene was dubbed in post production. As a result, lip movement is matched rather poorly to the audio.
