Brian Warner, better known as Marilyn Manson, is playing a role in writing the music for the upcoming flick. Updated
Marilyn Manson (who doesn't really need an introduction I think) has a part in the Resident Evil movie. Not as a member of the cast as I originally thought, but as composer. I previously wrote that he was playing a role in the movie, but that was incorrect.
Thanks goes to a reader, Aaron, for pointing this out.
You can find some more info about the movie at UpcomingMovies.com. Here's the premise of the movie straight from the film company: "The story focuses on a military unit that fights against a powerful super computer that is out of control. In order to save the world, the military unit must combat hundreds of scientists who have mutated into flesh-eating undead due to a laboratory accident."
