Clint Walker was never an amateur bodybuilder.He did pump iron all of his life and was a bouncer at one time.
He was doorman at a Las Vegas hotel when he was discovered.
He was close to 91 when he died.
PS: James Arness had a bum leg from a previous accident.
Lean Wolf can tell the story from knowing him, but Arness was in full time pain the last couple of years of Gunsmoke. It was from a war injury. During the battle of Anzio, Arness' right leg was peppered with machine gun bullets, and when the bones were set they didn't mend properly, leaving him with a slight but permanent limp. The trauma of the experience mellowed into aimlessness after the war.
