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.
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.
Factual error: The "Peace" symbol that adorns the uniforms of Byer's men did not come about until the late 1950's.
Factual error: For being set in 1943, the hair and clothing styles are definitely late 1960's fashion.
