Angel on My Shoulder (1946)

Gangster Eddie Kagle is plugged by his right-hand man and ends up in hell. An opportunistic Satan notices that the newly arrived Kagle is a dead ringer for a do-gooder judge that he'd like to get out of his way, so he offers Eddie the chance to get revenge on his killer in exchange for damaging the judge's rep. Kagle, however, finds that living the judge's life and being with the judge's fiance makes him want to be a better person which, coincidentally, means the devil cannot control him.

Clever and charming, but with a little less depth than it needs.
