Knights of Badassdom is a comedy that was made in 2010, but not officially released until 2013, due to production issues and difficulty finding a distributor. It is about a group of LARPers (live-action role-players) who accidentally resurrect a succubus during a game (they recite from an ancient spell book as part of their role-playing, thinking it was a prop book that they bought off the Internet), and the succubus is killing people while a game is going on. It is up to the gang to defeat the succubus, and believe in themselves as real heroes.
It stars Steve Zahn, Peter Dinklage, Jimmi Simpson (a McPoyle from It's Always Sunny in Philadelphia), Summer Glau, and Ryan Kwanten. I really liked it. It is silly and fun, with a good cast and good action and comedy, and done with passion for the LARPing community. It looks very cheaply-made, with cheesy special-effects, and looks as if the movie was made in just a couple of weeks, done with a small cast and filming nearly everything in a woods location. It is worth checking out on Netflix.
