Mitchum plays Jeff Markham, a private investigator who is hired by bad guy Whit Sterling (Douglas) to find Whit's girlfriend, Kathie Moffat (Greer), who shot him and absconded with $40,000. Jeff finds Kathie but falls in love with her and elects to run away with her rather than send her back to Whit. Jeff's partner, who lost out on the payment when Jeff ran away with Kathie, tracks them down. Eventually, Jeff goes into hiding and Kathie winds up with Whit, but Whit eventually finds Jeff and demands that Jeff do another job for him. Whit wants Jeff to find and retrieve some incriminating documents—but there's a lot more going on.
Out of the Past is considered a classic Film Noir and a career highlight for Mitchum (a Mitchum bio was subtitled "Baby, I Don't Care", a quote taken from this film). Has a place on the National Film Registry.
Random trivia: When this film was remade in 1984 as Against All Oddsnote with Rachel Ward and Jeff Bridges, Jane Greer played the mother of the character she played in this film.
This film provides examples of:
- Affably Evil: Whit seems to genuinely like Jeff. He also doesn't seem particularly bothered that Kathie shot him.
- Anti-Hero: Jeff wasn't a bad guy, but he wasn't a good one either. He took on Whit's job and go get Kathie, knowing Whit meant to harm or maybe even kill her. He covered up the murder of his partner to give Kathie a chance to get away. But you have to feel for the guy, because of Ann. He really did want to leave his past behind and be with her.
- Asshole Victim: Whit, as well as Kathie.

- Disney Villain Death: Just when Stephanos is about to shoot Jeff in the river, The Kid pulls him down to his death with the help of his fishing line.
- Downer Ending: Kathie kills Jeff right before she's gunned down by the cops, and Ann is tricked into thinking Jeff was about to run out on her with Kathie.
