For example, I’m not a John Wayne fan. He was a draft dodger and (IMHO) his acting was wooden. Some of the “singing cowboys” don’t really do it for me either. That’s not to say some of my own picks won’t suffer some of the same criticisms. Anyhoo, I’m talking about western characters who defined “tough guy” as you define it.
Peter Breck - Nick Barkley
Steve McQueen - Josh Randall
Clint - Bill Munny (and really, Gene for Little Bill) and Angel Eyes
Chuck Connors - Lucas McCain
Pa Cartwright had some steel in his belly. Lorne Greene did a good job with that role. Especially the episodes where he was alone in some town and didn’t have his kids to help him. He knew how to kick butt.
James Arness in the early seasons of Gunsmoke. Really tough guy in those early seasons. They watered it down after the anti-violence campaigns in tv took hold.
Jimmy Stewart surprised a lot of people in Winchester '73. He showed some acting range in his Westerns. His aw shucks, nice guy persona went away. Dan Duryea was really good as the villain, Waco Johnny Dean.
I don’t think Stewart ever played a villain? I don’t recall any roles like that.
Audie Murphy Westerns are really fun to watch. A real, highly decorated WWII soldier that went into acting. His Westerns are hard to find. They never came out on VHS. Not sure about DVD.
I regret not suggesting Dan Duryea in the original cowboy actor thread. I’d forgotten just how good he was. He played slightly psychotic smiling and affable villains. Smiling one minute and choking somebody out or shooting them in the back, the next. He played in Film Noir and Westerns. Ride Clear of Diablo with Audie Murphy is really good. Russell Johnson, The Professor is in that one too.
All I know is that Henry Fonda in Once Upon A Time In The West was the coldest and steeliest bad guy I ever saw in a western. Eastwood as Bill Munny is closest after that.
