Trivia: All of the scenes in this movie were shot in only one take and in one scene the technique really shows. When Jimmy Stewart is drunk, he ad-libbed hiccuping while he was talking. Cary Grant, not expecting the comic relief, had to look down at the floor to keep from laughing (you can see him grinning and collecting himself).
Trivia: Cary Grant refers to another character as a "mock turtle." Grant played the Mock Turtle in a 1930s film version of "Alice in Wonderland."
Trivia: This was Charlie Chaplin's first feature film with full sound.
