If you liked that movie, I HIGHLY recommend you watch Postal. Just to push you past the shock of who directed it into actually watching it, it's an Uwe Boll film. Completely discard any preconceived notions about his "film making", and just watch the movie. The opening scene will probably win you over. Think of it as a live-action version of South Park and you'll laugh HARD. I haven't even watched South Park since the movie came out, and I loved this movie. An instant classic IMO.
