alan tudykAlan Tudyk's bid for movie geek immortality gains more ground ... The Firefly vet has signed to play "Rock Brannigan," the leader of a group of misfit zombie hunters in upcoming horror comedy First Platoon.

According to Shock Till You Drop, the Tucker and Dale vs. Evil star joins a cast that includes genre vets Sid Haig (The Devil's Rejects), John Kassir (Tales From the Crypt), and Malcolm McDowell (Rob Zombie's Halloween remakes and, you know, a million other insane movies).

Indie director Chris Gabriel is helming the project, which is set for a spring/summer 2011 release date.

So ... first his Firefly character is resurrected in a comic book written by Patton Oswalt, and now the guy gets to fight zombies! Sounds like a good month for Tudyk and fans.
