Run Silent, Run Deep (1958)

'Run Silent, Run Deep' is a World War II set submarine film, and arguably the best of them, in which a returning first officer (Burt Lancaster) and a new commander (Clark Gable, in one of his last film roles) butt heads on strategy while on a Pacific patrol in 1943. Gable is trying to avenge the dead crew of his previous command, while Lancaster is trying to protect the crew he's serviced with before from unnecessary risk. I thought I knew what this film was and where it was going, a variation on another famous World War II Navy film whose name I won't say for fear of spoilers, but it ultimately goes in a different direction and derives much of it's late in story satisfaction from that difference. I highly recommend, a minor classic. ***1/2
