- Dawson Casting: Dickie Moore plays "The Kid", despite barely being younger than the main actresses in the movie. For instance, there is only one year between him and leading lady Jane Greer, and less than five months between him and Virginia Huston.
- Throw It In!: Robert Mitchum told Roger Ebert he smoked so much, that when the camera was rolling on this film and Kirk Douglas offered him a pack and asked, "Cigarette?", Mitchum, realizing he'd carried a cigarette into the scene, held up his fingers and replied, "Smoking." His improvisation saved the take, and they kept it in the movie.
- What Could Have Been: Humphrey Bogart read the script and, seeing the similarities between this and The Maltese Falcon, wanted to play Jeff. However, Warner Bros. didn't buy the material and RKO produced this movie.
- Working Title: Build My Gallows High, which is the name of the book it's based on. Though this was the title in the UK.
