Top 3 Roles?

Sam Elliott himself says:

Road House
Tombstone
The Big Lebowski

Actually what he said is: "I'm most famous for those three movies. It has nothing to do with me. They show that sh-t all the time on TV."

Actually, it DOES have something to do with him...

Sam Elliott is great at being the best thing about mediocre movies. I don't remember the last time I saw him in something I liked, but I always enjoy his solid, un-showy presence.
