You've probably heard of "crowdsourcing" by now, the idea that information and art can be created by many dispersed people contributing to a single whole. Now that idea is being used to create videos, using the free Vyclone app for iPhone. The app encourages multiple users to take video of an event, and, after a few minutes, combines those videos into a single movie. (You'll still get to keep your raw footage, if you prefer it to Vyclone's creation.) Finished movies can be shared with friends, and users can even create "director's cuts" if they so desire.
