- Enforced Method Acting: In a classic case of a director being emotionally manipulative, John Huston informed Claire Trevor (Gaye) that they were to film her song that very day. Trevor was not a trained singer, and had not even rehearsed the song yet. She also felt very intimidated by the A-list actors seated directly in front of her. The result was a hesitant, nervous, uncomfortable rendition, exactly the feeling Huston was hoping to get.
- Those Two Actors: This was Bogart and Bacall's final film together. They would have a radio show together, and they did a version of The Petrified Forest for television in the fifties, but contract problems and Bogart's illness and death prevented them from working on another film together.
