The Big Cool

Another actor who was great at pushing his characters one foot from normal (like Walken) was Burt Lancaster.

One of my all-time favourite movies: "Local Hero" - with Lancaster playing an eccentric oil billionaire wanting to buy a piece of Scotland - initially to put up a refinery. He sends a lead-man, "McIntyre" (played by Peter Reigert) to case out the acquisition but when he briefs him, all he wants to talk about is the sky. Great movie with a great soundtrack by Mark Knopfler.

 
Burt Lancaster was the ultimate tough guy actor. Paramount wanted him to play Don Vito Corleone but Copolla wanted Brando.
