Movies like Knights of Badassdom

In a valiant but pointless attempt to cheer up their freshly-dumped friend and former Dungeons and Dragons legend, Joe, two enthusiastic Live Action Role Players--Eric, a 27-level Grand Sorcerer in the making, and Hung, a medieval Master Rogue--drag their sad companion to a large-scale LARP campaign in the middle of a forest. However, things will soon spin out of control, as a malevolently cryptic dark incantation from the pages of a seemingly innocent prop book of spells, inadvertently summons a demonic succubus bent on destruction. Now, try to stop a slaughterous extra-dimensional being with several foam sticks and a handful of plastic swords.
