What parents need to know
Parents need to know that this popular Golden-Age-of-Hollywood comedy concerns multiple murders and madness, but without anything graphic shown. Violence is just roughhousing and a menacing display of knives. Some jokes (especially having to do with baseball stats of 1944) are badly out of date. There is an undercurrent of drinking, with poisoned wine a key plot element. This isn't in any way meant to be an enlightened view of families grappling with mental illness.
