Bill Mumy is not a name that fills the room, but he belongs in it. The actor who played Will Robinson in “Lost in Space” and later became Lennier in “Babylon 5” has a secret history with “The Twilight Zone.” He appeared in three versions of the show — the original series, a movie, and a revival — and one of those episodes remains among the scariest the series ever produced.
Mumy was born in 1954 and started acting young. His first “Twilight Zone” appearance came in Season 2, in an episode called “Long Distance Call,” where he played a boy who could speak with his dead grandmother through a toy telephone. That was a quiet start, but it set a pattern: Mumy kept showing up in strange places.
Mumy’s First Appearance
The second appearance was the one that made him famous. In Season 3, Mumy played Anthony Fremont in “It’s a Good Life.” Fremont is a six-year-old with omnipotent powers, the cruel, unpredictable whims of a child. The episode is one of the show’s finest installments, and Mumy is chilling as a capricious, god-like child.
“He was just the ultimate mutant and he was cranky.”
That line comes from an interview with The Television Academy, where Mumy explained his understanding of the character. He said Anthony was a metaphor for the “undisciplined United States,” but he loved the role because of how cranky the boy was.
The Third Episode
Mumy’s third “Twilight Zone” role came in Season 5, in the premiere episode “In Praise of Pip.” There he played the young version of a wounded Vietnam soldier who appears to his bookie father in a supernatural vision. It was a smaller part than Fremont, but it showed Mumy’s range across the show’s run.
Between Twilight Zones
Mumy stayed busy throughout the 1960s. He appeared in three episodes of “Alfred Hitchcock Presents,” though the legendary director reportedly traumatized him after a subpar take. According to the Television Academy, Hitchcock said, “Young man, if you don’t stand still, I’m going to nail your feet to the floor and blood will pour out like milk.”
Before “Lost in Space,” Mumy was one of three actors to play Darrin on “Bewitched.” He also featured in shows like “Wagon Train,” “I Dream of Jeannie,” and “The Munsters.” By the time he landed the lead in “Lost in Space,” he had built a resume that few child actors of his era could match.
The Movie Cameo
In 1983, Mumy made a small cameo appearance in the third segment of “Twilight Zone: The Movie.” That segment was a remake of “It’s a Good Life,” the episode where he first played Anthony Fremont. It was a brief return to the world he had left behind.
The Revival
The early 2000s brought Mumy back to “The Twilight Zone” again. A revival included an episode called “It’s Still a Good Life,” a direct sequel to the original. Mumy reprised his role as a now-grown-up Anthony Fremont. He also helped come up with the idea for the sequel in the first place, with his daughter Liliana playing Anthony’s child, who possesses the same terrible superpowers.
| Appearance | Show | Role |
|---|---|---|
| Season 2 | Original “Twilight Zone” | “Long Distance Call” (boy speaking with dead grandmother) |
| Season 3 | Original “Twilight Zone” | “It’s a Good Life” (Anthony Fremont) |
| Season 5 | Original “Twilight Zone” | “In Praise of Pip” (young Vietnam soldier) |
| 1983 | “Twilight Zone: The Movie” | “It’s a Good Life” (cameo) |
| Early 2000s | Revival | “It’s Still a Good Life” (grown-up Anthony Fremont) |
What He Missed
Mumy did not appear in Jordan Peele’s 2019 “Twilight Zone” reboot. Instead, he made a cameo in Netflix’s “Lost in Space” series. It was a small trade, but it kept his name attached to the franchise he had defined decades earlier.
A Career Spanning Decades
Mumy’s path through television is remarkable. He started as a child actor, worked steadily through the 1960s, and then moved into adult roles in the 1980s and 1990s. His work on “Babylon 5” was notable, and his return to “The Twilight Zone” for the revival showed that he remained connected to the show.
The legacy of Anthony Fremont is a mark of that. Mumy understood the character as a metaphor for the “undisciplined United States,” but he loved him because he was cranky. That combination of insight and affection is rare, and it is why the episode remains one of the show’s finest installments.
Mumy’s work on “The Twilight Zone” is a gift to anyone who loves the show. It is a reminder that the show was always about ideas, and that the actors who played those ideas were always up to the task. Mumy’s career is a quiet legend, and it is worth celebrating.
