In this comedy, Paul Muni plays a recently murdered gangster who finds himself roasting in Hell. Muni cant believe that hes in for All Eternity and keeps trying to bust out, which brings him to the attention of the Head Man (Claude Rains), who calls himself Nick. Nick strikes a bargain with Muni: Theres a troublesome honest judge on Earth whos been shipping too many souls to Hell; if Muni will take over the judges body and begin performing bad deeds, Nick will set him free. Muni readily agrees, eager to settle the score with the ex-partner (Hardie Albright) who bumped him off. Once he becomes the judge, however, Muni discovers that he is utterly incapable of performing any misdeeds--and when he falls in love with the judges fiancee (Anne Baxter), Muni becomes determined to wriggle out of his agreement. Angel on My Shoulder is based on a story by Harry Segall, whose previous play Heaven Can Wait was filmed as Here Comes Mr. Jordan, also with Claude Rains. ~ Hal Erickson, All Movie Guide
