Crash the Movie Trailer
This is so much fun. Here is the deal. On the official Wedding Crashers site, they have set it up so that you can actually put yourself in the trailer. You just need a headshot of yourself and you can put yourself in the trailer. You will show up at the points where the character does. Your mouth will move and everything. You can be Christopher Walken, Vince Vaughn, Owen Wilson, Rachel McAdams, or Isla Fisher. It is fun to play with for a few minutes.
