Pulp Fiction. I can just watch the scene where Bruce WIllis' character walks to his apartment over and over.
Then I'd think about Stardust Memories and change my vote to Annie Hall.
Then I'd remember that Annie Hall won the best picture oscar in the same year that Star Wars came out and I'd wonder how many people were going to pick Star Wars ahead of something more awesome like Raiders of the Lost Ark or Back to the Future. Then I'd check what everyone had posted before me, become self-conscious and not post.
Midnight Run. That's the knee-jerk response. If I thought about it longer than five seconds, I'd easily find better movies to take that place. But there's just something about Midnight Run, that no matter how many times I watch it, I'm always ready to start it right over again.
