In 2000, Sam was nominated for a SAG Award for Outstanding Performance by a Cast in a Theatrical Motion Picture for The Green Mile.
Sam: (on preparing to play a sex addict in Choke) Well, I don't think I've ever been a sex addict, so the role took some work. I couldn't really identify with what my character was doing at first. I went to some sex addict rehab meetings just to find out more about what these people are all about. I went anonymously and I think I was only outed one time.
