Hell, too many to list them all, here are a few...
Al Pacino, Robert Deniro, Morgan Freeman, Demi Moore, Denzel Washington, Ed Norton, Jim Carey, Kevin Spacey, Val Kilmer (if only for his role in 'Tombstone'...classic, one of the best roles ever, by anybody), Tom Hanks, Halle Berry, and believe it or not - Brad Pitt (can't stomach the celebrity gossip stuff, but have always thought him to be a great actor and very diverse), etc., etc.
My parting shot: Nicholas Cage - indefinitely removed from any of my such lists, as these days he just can't seem to get it right anymore.
