Can listen to either of them speaking for hours.

Shawshank is by far #1.....Nurse Betty was entertaining.

That it is. Cannot watch that very often. Not very entertaining.

Tough question! He's good no matter what the movie or the role. My favorite though is The Shawshank Redemption, followed (closely) by Unforgiven, and Robin Hood Prince of Thieves.

I also admire his versatility. He's an accomplished stage actor as well, and narrates quite a lot of TV stuff. His distinctive voice and impeccable diction lend an aura of gravitas to whatever he does.

AND he's one heck of a singer as well.
