A fine film
I saw this for the first time a few days ago and found it very entertaining. In fact, if they had only changed the ending a bit, this film would come close to generating the same feel-good-glow that It's a Wonderful Life generates.
[SPOILERS]The film traces the afterlife of a cruel mobster (Muni) who is brought back by Satan himself to earth in order to take possession of a crusading judge (who happens to look exactly like the mobster) who has been a real obstacle to some of Satan's efforts. The idea is for Muni to wreck havoc with the judge's reputation by simply being himself. Unfortunately for the Devil, Muni gradually reforms as he meets many of the judge's friends, especially the fiancée, played by Anne Baxter. He falls in love and the transforming power of this love enables him to foil the Devil's plans. The ending, however, has him returning to Hell with Satan--though because he outsmarted him, Muni is able to blackmail the dark lord into making him a "trustee." I think what should have happened, is that when Satan starts to take Muni back to Hell, an angel should have intervened and brought Muni to heaven. Properly staged, this would have been a much more upbeat ending and probably would have propelled this film to "classic" status.
Cheerio!
Fighting for Truth, Justice, and making it the American way.
