What Movie(s) Had The Most Impact On Your Life?

It's rather crazy if you think about it...a movie can simply be just what it's intended to be be. A movie. An hour and a half of intertainment just to keep you busy or it can be more. The movie can be a movie you saw at the theaters or at home. For me , Full Metal Jacket changed my life. I joined the military just a few weeks after watching it. I don't have any regrets...lol well maybe a few? So. what movie had some impact on your life?
