Patton Oswalt In 'Big Fan'

This is the trailer for the movie "Big Fan" and it looks like it could be pretty good. I've always liked Patton Oswalt and this bit seems more of a departure for him compared to his usual roles as the funny friend or sidekick. From the movie's official description: "The life of a parking garage attendant is turned upside down after an altercation with his favorite player on the New York Giants."
