Best movie intro ever?

Might be stretching it a bit here. But whenever I want to think of a great opening this one from Ali comes to mind. One of the most underrated movies as well. The main thing it makes me feel is the urge to go for a run. This is probably the best ad for running [workout/training] never created. They got it. The reason one go out. You dream for glory and winning the Olympics of course, but in the end it's only for yourself that you do it. And Sam Cooke is worthy his mentioning too. Yes.
