In Knights of Badassdom, live action roleplayers Peter Dinklage, Ryan Kwanten, Steve Zahn, Summer Glau and Patrick Stewart accidentally summon a demon to Earth during league play. You know, like you do. It's unlikely that you require much more information to become excited about this film, but we can tell you it's directed by Joe Lynch and combines stars from such genre highlights as Game of Thrones, True Blood, Terminator: The Sarah Connor Chronciles, and Star Trek: The Next Generation, and was among the most talked about trailers last weekend at Comic-Con International in San Diego.

You can watch that slighty NSFW trailer after the jump.
