Younger daughter Monica is a sadist who keeps live rats as pets and frequently mutilates them and other small animals.

Youngest son Malcolm is a halfwit with animalistic tendencies; the family keeps him locked in a room with live chickens.

Youngest daughter Diana returns home from medical school in Scotland with a new husband, a former classmate named Gerald, of whom Pa heartily disapproves.

Some scenes were filmed nearly two years later in Staten Island at the request of producer Mishkin to pad out the short running time.

Because of the low budget, Milligan actually acted in at least two different roles during the production under two different names which included playing a gunsmith who sells Diana a pistol containing silver bullets,[1] as well as a pawnshop owner named Mr. Micawber in the re-shot scenes involving Monica and the rats (which were added after Willard achieved popularity).
