Battle of the actors!

Walken owns Douglas in terms of acting skills, variety of roles, and additional comedic cameos and lines (backed with his awesome voice).

Walken hands down.
 
yeah, an then Walken would continue to battle the next actor
(i.e. walken vs. douglas, then if walken won it would be walken vs. clint eastwood, then the winner of that takes on a new actor and so forth.
