Major physical and voice/accent change
Watching him in GUNSMOKE "The Wedding", S17/Ep24, (!972) and I'll be darned if he even looks or sounds like he does in later years/today. Had to go on to the IMDb to check out who he was. Almost like a whole different person. Guess one has to do what one has to in order to hang onto the acting career.
The best revenge: Live well, enjoy life and be happy. Drives any haters crazy.
