I found three more actor/actress that were in the "Twilight Zone":
Val Avery - "Dead Weight," "Most Crucial Game," "A Friend in Deed," and "Identity Crisis"
Pippa Scott - "Requiem for a Fallen Star"
John Fielder - "Blueprint for Murder" He was also the voice of Winnie-the-Pooh😊
Don Keefer was the coroner in "The Most Crucial Game" and "Death Lends A Hand," and also in one of the most famous TWILIGHT ZONE'S. He was the man who becomes a jack in the box in It's A Good Life."
Mariette Hartley. "The Long Morrow."
