The No. 1 rule of scene-stealing: If you do it well enough, you'll get your own movie. And Russell Brand's American film debut more than accomplished that. On paper, the rock star who cheated with the protagonist's girlfriend should be easy to hate. But like Peter, we couldn't help but love Infant Sorrow frontman and Tommy Bahama hater (the shirt, not the man) Aldous Snow. Take away his wealth and fame and Aldous is just a man looking for his missing sandal and a queen for the Sorrow Suckers ("I don't know why they call them that"). Thankfully, his search for both continued in 2010's Get Him to the Greek, which taught us that you should always be scared of a Jeffrey.
