There have been many different fan made versions of Star Wars, but none better than the one Simon Pegg and Nick Frost did for CollegHumor. Take a look at their version of the George Lucas classic, and get a bonus trailers for Paul, when you click through.
Paul is a filthy foul mouthed alien (voiced by Seth Rogen). I guess that's about all you need to say about this movie. Enjoy the trailer but keep in mind the language is very, very profane.
