Caught this one on our 'On Demand' cable service last night. I'm a big fan of 'submarine movies' with all their cliches and standardized plotlines (the 'silent running sequence', the 'depth charges sequence', the 'battle weary captain' the 'going too deep and the pressure is going to crush us sequence'). I wasn't expecting much at first, the acting by the bit players was wooden and the dialog a little corny, but once the two main characters were introduced and the chase begun, this turned out to be a pretty decent little war film. Mitchum and Jurgens were both great, and it was interesting to see a war film that actually avoids taking sides, and treats the enemy with a bit more respect and intelligence.
Some other favorites: Run Silent Run Deep, Tokyo Bay, U-571, Das Boot, Crimson Tide, The Hunt for Red October
