"People are like, so your first Western! But it's not. I did a film called Geronimo: An American Legend. It was a hell of a cast. Jason Patric... Gene Hackman... Robert Duvall... and Wes Studi played Geronimo. I haven't seen it in years... It came out at Christmas in 1993 I think." Hollywood action man Matt Damon insists his new movie True Grit isn't the only Western he's starred in.
