Revealing mistake: When the mayor's wife attempts suicide by stuffing herself with pills, she is lying behind a sofa, only her arm and the pill bottle being visible as she pours the contents into her mouth. In the next shot (a close-up), however, the crown of her head is visible, and it is evident that she pours the pills over the top of her head.
Which Way To The Front? (1970)
1 revealing mistake - chronological order
Directed by: Jerry Lewis
Starring: Jerry Lewis, John Wood, Jan Murray, Steve Franken
Factual error: Due to paranoid fear of sabotage, all Japanese Americans were interred in camps along the west coast during WW2. So it would have been MOST unlikely for Yamashita (especially considering his military background) to simply walk about freely and to have work as a gardener.
Adolf Hitler: Did you know that last year more people died from cigarette smoking than from bombings?
Brendan Byers III: What will you do about that, Führer?
Adolf Hitler: Increase the bombings.
Trivia: Jerry Lewis' real son, Ron, plays Lieutenant Levitch in the film.
