Greatest Movie of All Time

This comes up in conversation every now and then, right? Favorite movie, actress . . . worst . . . I was channel hoping tonight and came across The Dirty Dozen. That is a great movie. While not everyone's cup of tea being a war movie and all, it still has to rank up there on anyone's list of great movies. I have to admit, I tend to like modern movies more than old. But, this is a classic. It's very watchable by today's standards. What a cast! Simply a great movie!
