Fanboys

Kristen Bell dressed as Princess Leia in the slave outfit? If you need more, there's also the real Princess Leia, Seth Rogan as a pimp, William Shatner as himself, Jay and Silent Bob, Ethan Suplee, and Billy Dee Williams!
The story revolves around a group of friends struggling with conflict of real life and following their childhood dreams. Childhood dreams obviously win out or it would have been a very short movie. The film doesn't bring much new to the road trip genre, but it is an enjoyable 90 minutes.
The jokes are accessible to most, but if you hate "Star Wars," you're probably better off avoiding it.
