Like my recommendation for Neal McDonough, I have to recommend Michael Biehn for: Anything. He just wasn't in enough... But if I were casting, I would put him in almost anything.
Don't know what specific role he'd play, but I think he's got that Star Wars look that he would fit in well enough. Almost shares a ressemblance to Mark Hamill, so if you needed someone to play an elder member of the Skywalker clan...
