^ In that particular picture, that's him playing the role of the Stranger from The Big Lebowski, and to be honest, that's the only movie I've seen him in. I think he does fit the role of grizzled old man, because taking a quick peek at his filmography, he did seem to do a lot of westerns. Oh, and you can't go wrong with a mustache as awesome as what he has. :3
