Submarine Movies

There are a couple of new submarine-themed movies in the news. There's a documentary about WWII submarines and Submariners called "Dive: A Submariner's Story"; you can watch the trailer here. It's supposed to be released sometime this year.

There's also an Australian short film about Russian submariners called "Deeper Than Yesterday" that's being entered at Cannes, so it's probably artsy-fartsy.

What are your favorite submarine movies?
