It's a Mad, Mad, Mad, Mad World/Trivia
- All-Star Cast: Everyone from Jerry Lewis to the Three Stooges is in this movie.
- Hey, It's That Guy!: Everyone.
- Although, in an odd inversion of Retroactive Recognition, some of the cameos are by early-'60s TV personalities who would have been readily identifiable to 1963 audiences but are all but forgotten today.
- Playing Against Type: Stanley Kramer was a director best known for dramas regarding social issues (On the Beach, Inherit the Wind, Judgment at Nuremberg, etc). Additionally, many of the cast were better known for being stand-up comedians or sitcom stars, as opposed to "pratfall" comics.
- What Could Have Been: Ethel Merman's mother-in-law character was originally written as a father-in-law, with Groucho Marx in mind.
