Continuity mistake: When Dennis is in the bathtub you see some toys floating around in the tub. When it cuts from above him the toys are gone. Instead the whole tub is covered with foam. (01:28:20)
Mrs. Martha Wilson: Weren't you a fat boy?
George Wilson: I was husky.
Trivia: Five years after this film was released, Christopher Lloyd—who plays the film's villain, Switchblade Sam—starred in the made-for-TV film "The Ransom of Red Chief," where he played a similar role: a criminal who kidnaps an unruly young boy who ends up turning the tables on his captors. Funny enough, Lloyd in that other film was also named Sam.
Question: Why did Dennis run away from George and Martha's house?
Answer: Because of what George said to him in the house after he was robbed. He hurt Dennis' feelings so he ran away.
