Criss Cross (1949)

Burt Lancaster returns to Los Angeles to find his ex-wife Yvonne De Carlo. Even after marrying gangster Dan Duryea, she’s willing to rekindle their romance. To hide their affair, Lancaster proposes an offer to the mobster, a plan to rob the armored car company he works for. It’s a bleak story that, even with some time jumping, makes great use of a short run time. As the title suggests, there is plenty of double crossing and reasons to question loyalties, barreling towards an ending that doesn’t seem like it’ll be positive for anyone.    

Side note: Corky, the dog actor who looks incredibly like my own dog, is also in this film. He even jumps into people’s arms like my buddy.
