Barry Atwood, Surak in “The Savage Curtain” is in the Rawhide episode, “Corporal Dasovik” as the Ute Chief Ollocot. He played the character like a Vulcan. Perhaps he was type cast.
Morgan Woodward, Dr. Simon Van Gelder in “Dagger of the Mind” and Captain Ronald Tracey in “The Omega Glory", in the Rawhide episode, “The Photographer” as Kale Maddox, one of several crooks who want to be immortalized by the photographer Taylor Dickson, played by Eddie Albert.
Lenard died in 1996.
He was in several films I’ve seen, among them the prosecutor in “Hang Them High”.
I guess I did not recognize him without pointed ears.
Over in “TV shows only you remember” the series “Brimstone” came up. As it happens I’m doing a rewatch on that one and have already spotted Rosalind Chao. But the episode “Executioner” has Jeff Corey, who played Plasus in TOS, Michelle Forbes who played Ensign Ro on TNG, Robert Knepper who played Wyatt Miller on TNG and also Gaul on Voyager. Series regulars John Glover played Verad on DS9, and Lori Petty played Noss on Voyager. So, five actors with six roles between them across four series.
Even more impressive. That same episode also featured Scott Lawrence, who played Garon in the ST Voyager episode “The Void”. Lawrence is an African-American character actor with a long resume, one of those “Oh, it’s that guy” guys. So the total for that episode is actually six!
