Heaven Only Knows is an amusing fantasy done in an almost straight manner to give it credence. There are no astonishing miracles of heavenly power, no fantastic harps and wings to stretch the imagination too far. It’s a tongue-in-cheek treatment that lends a lightness to what, otherwise, could have been rather heavy drama.
Story concerns an angel visiting earth to rectify a heavenly book-keeping error. He had permitted a man to run loose without a soul because his destiny hadn’t been properly entered in the books. On earth, he finds the soulless creature just that. He’s a ruthless killer operating a saloon in Montana.
The angel’s chore is to bring together the killer and the schoolmarm because, according to heaven’s books, they should have been married for two years.
Robert Cummings plays the visiting angel with just the right touch. There’s a refreshing naiveness in the angel’s conduct in the tough western mining town; his openly friendly approach to his task and occasional chagrin when he encounters a situation where a miracle would have been a big help. Brian Donlevy, too, sparks his assignment as the man without a soul.
