* MoneyDearBoy: Both leads were only in the film to fulfill contractual obligations, both [[ItWillNeverCatchOn thought the film would flop,]] and both would go on to win [[UsefulNotes/AcademyAward Oscars]].
* RealLifeWritesThePlot: The 'Walls of Jericho' was put in because Claudette Colbert refused to undress on camera.
* TheRedStapler: Unusual example. The film is partially credited with the idea of making it cool to go without an undershirt.
* SleeperHit: Arguably the original example. The film was made on a low budget by a small studio and a director that had yet to make a name for himself. Columbia had little faith in the film, and spent almost nothing on advertising, while both of its stars wanted to distance themselves from the project. The film was originally released to average box office, but positive word-of-mouth eventually spread, and the film amassed a huge cult following, especially in rural areas. It later went on to sweep the Oscars that year, unheard of at the time for a smaller movie.
* ThrowItIn: The at-the-time shocking ShirtlessScene came about because Clark Gable had trouble removing his undershirt to keep the flow of the scene going - so he went without it.
* WhatCouldHaveBeen:
** Myrna Loy, Constance Bennett, Margaret Sullivan, Carole Lombard and Miriam Hopkins all turned the lead down. Warner Bros also refused to loan out Bette Davis, who amusingly would have an infamous AwardSnub to Claudette Colbert for this very film.
** Claudette Colbert initially refused to ShowSomeLeg for the famous hitchhiker scene. So they got a double to do it instead. When Claudette saw the take, she didn't like the double's leg, and ended up showing her own after all.
* The film is rumored to have been a primary inspiration for WesternAnimation/BugsBunny, thanks to a scene where Peter talks quickly while chewing on a carrot, as well as another scene where he pretends to be a gangster and invents a person named Bugs.
