Twilight Zone Actors Who Guest Starred on Seinfeld


Rod Serling‘s The Twilight Zone is a trademark series that changed the landscape of television with its innovative storytelling, exceptional performances, and powerful themes, and has since become a staple in television history and pop culture. The series is widely celebrated for its exceptional variety of classic stars such as Ida Lupino, Lee Marvin, and Burgess Meredith, and future icons like Robert Redford, Charles Bronson, and Elizabeth Montgomery. Although the show featured a collection of familiar faces, there are some notable players from the Fifth Dimension who managed to cross over into one of the greatest sitcoms of all time, Seinfeld.

Much like The Twilight Zone, Seinfeld was a cultural phenomenon that made its mark with timeless antics, relatable humor, and lovable, over-the-top characters, forging its own place in the history books of American television. Throughout the show’s nine-season run, Seinfeld subtly snuck in former TZ players such as George Murdock and Jesse White into various episodes, with many being a part of some of the show’s most memorable moments. From the legendary Bill Erwin to former B-Western star Peggy Stewart, these are six stars from The Twilight Zone who also appeared on Seinfeld.

Bill Erwin was a seasoned character actor who appeared in over two hundred and fifty movies and television shows, including I Love Lucy, The Untouchables, Somewhere in Time,, and Home Alone. Born in Honey Grove, Texas, Erwin initially found immense success in television and made his first of four appearances in The Twilight Zone in season one, episode 3, ‘Mr. Denton on Doomsday.’ The majority of fans recognize him for his role as Peter Kramer in one of the show’s most famous episodes, season two, episode twenty-eight, ‘Will the Real Martian Please Stand Up?’ Other appearances include uncredited roles in season one, episode five, ‘Walking Distance,’ and season four, episode five, ‘Mute.’

At the age of seventy-eight, Erwin landed a guest spot on Seinfeld in season four, episode eighteen, ‘The Old Man,’ as a cooped-up and foul-mouthed elderly man, Sid Fields, who is paired with Jerry as part of the Foster-A-Grandpa program. Between his character’s lack of a filter and constant poking at Jerry for his own amusement, Erwin left fans and critics with a lasting impression that earned him an Emmy Award nomination for Outstanding Guest Actor in a Comedy Series.

Lois Nettleton

Lois Nettleton was an award-winning television actress from Illinois who initially found success on Broadway and started taking on various guest roles in popular television shows by the mid-1950s. In 1961, Nettleton starred in season three, episode ten, ‘The Midnight Sun’ of The Twilight Zone, as a young woman, Norma, who is desperately trying to survive the scorching heat as Earth starts moving closer to the Sun. Considering the intense premise and small cast, Nettleton delivers one of the most sensational performances in the Fifth Dimension and is one of many stars who brought sophistication and genuine talent to the series’ timeless legacy.

Although Nettleton mainly took on dramatic roles, she wasn’t without a sense of humor and made a guest appearance on Seinfeld in season six, episode six, ‘The Gymnast,’ as Mrs. Enright, who is the mother of George Costanza’s (Jason Alexander) girlfriend at the time, Lindsay (Jessica Hecht). Even though her role was minor, fans will famously remember the scene where she watches on in horror as George secretly eats from the family’s trash can. Her shocked facial expression and uncertainty mixed with panic and sheer disbelief ultimately turned the already-humorous scene into one of the show’s most unhinged.
