The film follows a high school kid who goes to a fantasy / sci-fi writer's camp, where the most famous sci-fi author in the world (Flight of the Conchords Jemaine Clement) steals his book idea. We see each author's version of the book acted out, with Sam Rockwell in the lead each time.
This movie looks fucking hilarious! I haven't laughed so hard from a movie trailer since Dumb & Dumber. Also Sam Rockwell is gold in this film. Check it out!
