Sci-fi queen Summer Glau (“Firefly”) stars as a live-action role player in director Joe Lynch’s (Wrong Turn 2) upcoming horror-comedy Knights of Badassdom. Photos of the 29-year-old stunner in costume—with costars Ryan Kwanten (“True Blood”) and Steve Zahn (Perfect Getaway)—have the web, courtesy of EW.

Knights of Badassdom centers on a group of role playing geeks who unwittingly conjure up a powerful succubus that sets her eyes on their newest member. The film also stars Peter Dinklage (“Game of Thrones”), Danny Pudi (”Community”), and Margarita Levieva (Adventureland) as the sexy demon.

Glau is part of Clatto’s Top 20 Hottest Women Working in Horror/Sci-fi Today.
