@sharkbait. Dante's Peak is a classic! @mikeconley11 Points for thinking outside the box, but I don't want comedy. What else you guys got?
Waterworld -- the disaster already happened and the movie is set in the aftermath Star Wars -- the planet, Alderran was completely obliterated
Apocalypse Now, Platoon, Full Metal Jacket, Schindler's List, The Bridge on the River Kwai, Paths of Glory, The Pianist, All Quiet on the Western Front and The Deer Hunter if you're up for a war film
Do post-apocalypse movies count? In that case: The book of Levi, or The road. Otherwise: The perfect storm
Keep the suggestions coming guys! For every few posted I find one I haven't seen or haven't seen in a long time
