Inferno is a small but excellent 1953 film about a beautiful woman (Rhonda Fleming) and her lover (William Lundigan) who leave the woman's husband (Robert Ryan) alone in the desert with a broken leg, assuming he'll croak. The story focuses on Ryan's character trying to survive in the desert and what he learns about himself.
With gorgeous Rhonda Fleming in the movie, it's done in color. A chimpanzee could have played her part - there's precious little acting involved - but she certainly adds tremendous beauty to the production. She and another spectacular redhead, Arlene Dahl, both were getting larger roles in films at the time the studio system was winding down. Ten years earlier, they might have ruled the world. William Lundigan is appropriately cold-blooded as her horny lover, and Larry Keating is an appropriately concerned business associate.
But this is Ryan's film, and he's top-notch. His thoughts come over as voice-over, and you're pulling for him every step of the way, despite everyone describing him as unpleasant.
Excellent film, quite a surprise.
