All in a Night's Work is a 1961 American Technicolor romantic screwball comedy film directed by Joseph Anthony and starring Dean Martin and Shirley MacLaine.

The young playboy Tony inherits the paper but is left with a board of directors that thinks he's unsuited for the task, plus a hotel detective who thinks Tony should know about a girl who was seen running away from his uncle's Palm Beach hotel room, wearing nothing but a Turkish towel and an earring, on the night of his death.

When the dog's muscular owner appears, Tony beats a hasty retreat and leaves Kingsley to take the heat.

When Kingsley's strait-laced parents come to New York to meet Katie, they quickly discover her inability to cook and her low tolerance for alcohol.

Kingsley Jr. is exposed as an unworthy "Mamma's Boy", and Tony demonstrates his loyalty by proposing to Katie in a crowded elevator of strangers.
