I think everyone is aware of TOS stars/guest stars on The Twilight Zone, but a few ended up on Serling's final series, Night Gallery: William (Matt Decker) Windom: "They're Tearing Down Tim Riley's Bar" & "Little Girl Lost" Glenn (Cochrane) Corbett: "Brenda" Lou (Lokai) Antonio: "Death on a Barge," which was directed by Nimoy. Leonard (some Vulcan, maybe Stonn...T'Pol?) Nimoy: "She'll Be Company for You" co-starring Kathryn (Gem / "The Empath") Hays. Jeff (Plasus) Corey: "The Dead Man" Barbara (Lenore) Anderson: "Fright Night" Susan (Vina) Oliver: "The Tune in Dan's Cafe" Gary (Gary Mitchell) Lockwood: "The Ring with the Red Velvet Ropes" *Charles (Landru / Jaris) Macaulay: "The Funeral" *Barry (Surak) Atwater: "The Doll of Death" Louise (Rayna) Sorel: "Pickman's Model" & "The Dead Man" I'm sure there's more TOS guest stars on NG, but I cannot recall any at the moment. *vampire trivia: Macaulay portrayed a very undead "Count" in the Night Gallery episode, and Dracula in Blacula, which starred William (Daystrom) Marshall. Atwater's best known role was a vampire--Janos Skorzeny in The Night Stalker TV movie.
