It wasn't my fault! Not really. It was the TV's fault. It insisted on playing Crimson Tide for me after the documentary/movie Hiroshima. Hiroshima's a good movie, but Crimson Tide was the real trap for me. I can't start watching that movie without watching it all the way through. It's one of my favorite movies, right up there with The Hunt for Red October, Aliens, Star Trek II, and The Right Stuff.
As you can tell, I'm a Sci Fi fan and a sub battle fan. Heck, a good portion of Star Trek II was more or less a sub battle done in space. There's very few things like a sub battle to give you a real slice of the old cold war tensions. That mix of fear, and claustrophobia, mixed with patriotic duty makes for great movies. They always get to me.
I'm going to have to go complete my collection of Sub movies, and get K-19, U-271 and Das Boot to go along with the Crimson Tide and Red October DVDs I already have. Some day I'm going to hold a day long sub movie marathon. That'll be fun.
