Tom Selleck’s Golden Retrever.

Meryl Streep for all the variety of roles she has played so well.
Tom Hanks is another versatile actor who does a great job in a lot of roles.
All of the other guys that were named. Might add Charles Bronson to that list.

I judge an actor by their ability to stand out in different roles. Watch back to back Double Indemnity and Christmas In Connecticut. Done deal!

Robert Duvall, Number one by a long way
Val Kilmer
Robert Redford
Willem Defoe
Tommy Lee Jones

Another favorite of mine was Lee Van Cleef

Tom Hanks comes to mind. Never seen a bad movie he’s in.

Always enjoyed Sean Connery
For modern action actors, hard to beat Jason Stratham

Morgan Freeman
Robert Redford
Robert Duvall
Harrison Ford
Daniel Day Lewis

Although not an ol classic... I like Patrick Dempsey a good deal.

How about Moses a.k.a. Charlton Hesston.

I loved the characters Dennis Hopper played.

I feel that way about James Cagney and Burt Lancaster

All of the Bond girls.

I guess I soured on Tom Cruise when he was cast as Jack Reacher. Anyone who has ever read the Lee Child novels knows Jack Reacher is 6-5 and 250 pounds. Not to be portrayed by a 5-7, 150 pound actor. A better choice would have been someone like Steve Austin or John Cena in that role.

Lassie, Rin Tin Tin, Cheetah,Clyde,And the Dukes pal Dog.

I like the guy, but his acting left a bit to be desired imo. lol

I'm surprised that nobody has mentioned any of the following.
Gregory Peck
Burt Lancaster
James Garner
Bruce Dern ( without equal in his typecast roles)
Robert Michum
