It might not have been their very first paid acting experience, but it seems that quite a few actors and actresses appeared on Twilight Zone before they became famous. Somehow Rod Serling seemed to have an ability to cast people who would later become famous in TV and movies later in their careers.
I’ve been watching a few episodes on the New Years Twilight Zone marathon and so far I’ve seen William Shatner (Twice) Nick of Time and Nightmare at 20,000’. Robert Redford in Nothing in the Dark. William Windom in *Five Characters in Search *of an Exit.
The George Takei TZ episode is on YouTube. Certainly one I hadn’t seen before and I grew up watching TZ. I wonder if it ever aired. It had a few scenes that some might say are racist. I doubt it would be part of any present day TZ marathon.
I just did an IMDB search for actors common to Twilight Zone and To Kill A Mockingbird (because in the past two days I’ve seen the William Windom episode as well as the one with Mary Badham as “Sport” and Collin Wilcox Patton, who played Mayella Ewell) and also turned up Robert Duvall, Frank Overton, and a few others. I’ve never seen the Robert Duvall episode, I don’t think.
Shatner was on Alfred Hitchcock Presents before he was on Twilight Zone, IIRC (“The Glas Eye”). Both he and Niomy both appeared on The Outer Limits, as well.
NBecause he appeared in so many Twilight Zone episodes, John Landis had Burgess Meredith provide the opening narration for Twilight Zone — The Movie.
Jack Klugman was in three different episodes, IIRC. Jonathan Winters, Art Carney (clearly well known by them), Robert Redford, Burt Reynolds.
Russel Johnson played a scientist in one episode (and had already played scientists in This Island Earth and Attack of the Crab Mopnsters). The man was DOOMED to play The Professor on Gilligan’s Island.
If anyone would obsess enough to produce a site cataloguing all the episodes on INSIGHT (dubbed a “Catholic Twilight Zone”), a list of actors would be as long & have a lot of overlaps with TZ, I bet.
