Nathan Fillion (when asked what he likes about playing a villain): Being able to be evil. You can't do the evil things that you want to do in real life. You certainly can't because it's against the law and society says all that they have to say about being evil. You want to be bad everyday. You want to do the bad evil things that you can't get away with and now I'm able to be bad and super strong. It's a fantasy.
