Here's the trailer for Knights of Badassdom, the horror comedy starring Summer Glau, Peter Dinklage, Ryan Kwanten and Danny Pudi. Check out this awesome trailer and see Summer Glau, who plays ass-kicking LARPer Gwen, brandish a sword and kick ass the way the geek gods and 'Knights of Badassdom' filmmakers intended.
Some info about Summer's character Gwen, from io9 article.
Not a lot has been revealed about Summer Glau's character Gwen, but the panel revealed a few key details. Glau explained that Gwen is essentially midway between Joe and the serious LARPers. She's there with her hardcore LARPing cousin Gunther, and she alternately can either get really into the fantasy or be reserved or cool. Glau said she finally gets to play a character who smiles a lot and is basically normal, marking a pretty big departure from her usual roles.
"Knights of Badassdom was next on the docket, and I was pleasantly surprised. It looks pretty funny, and I like how enthusiast director Joe Lynch was about the whole thing. Of course, geek god Summer Glau got huge applause when she came out, as did True Blood‘s Ryan Kwanten."
