Deliberate mistake: During the song Adelaide's Lament, Adelaide goes to her medicine cabinet, opens it, and there is a cut to a shot from "inside" the cabinet as she surveys all the medicine she takes to treat her "cold." From the inside, the cabinet is almost twice as wide as it is when it shows her open and later close it from the outside.
Guys and Dolls (1955)
1 deliberate mistake - chronological order
Directed by: Joseph L. Mankiewicz
Starring: Marlon Brando, Frank Sinatra, Jean Simmons, Vivian Blaine
Continuity mistake: Right before the "Pet Me Poppa" number, there is a shot showing some sort of smoky substance lurking on the stage. The shot also includes a man walking onto the stage. The shot changes to a close up shot of him making an announcement, and the smoke is gone. When the shot changes to show the entire stage the smoke is there again.
Big Jule: Well, I used to be bad when I was a kid, but ever since then I've gone straight, as has been proved by my record: Thirty-three arrests and no convictions.
Trivia: Nathan was added into Nicely and Benny's number 'Guys and Dolls' to increase Sinatra's singing part.
