Looks like a cross between George Clooney and Jack Elam
I sat through the whole film thinking he looks like two famous guys mated; one who is good-looking and the other very goofy-looking. It wasn't until a half hour after it ended that it occurred to me:
George Clooney (needs no introduction) and the cockeyed "what in tarnation?" Western character actor Jack Elam. Maybe that's why his wife isn't fond of the beard.
I found the documentary fascinating for other reasons too.
