TL;DR
Jim Henson’s 1969 teleplay ‘The Cube’ is an experimental, surreal episode that prefigures themes of dystopia and reality questioning seen in Black Mirror. It remains largely obscure but offers a unique glimpse into Henson’s darker, more experimental side.
Jim Henson’s 1969 teleplay ‘The Cube’ has gained renewed attention as an early, experimental work that resembles modern dystopian anthologies like Black Mirror. The episode, largely overlooked since its original broadcast, features a man trapped in a mysterious white cube, raising profound questions about reality and identity.
Produced for the NBC anthology series ‘Experiment in Television’, ‘The Cube’ is a 53-minute bottle film set entirely within a single room. The protagonist awakens in a featureless white cube with no apparent exits, and as various characters enter and exit through invisible doors, the narrative explores themes of perception, sanity, and control.
During the episode, the man encounters bizarre interactions—such as a woman claiming to be his wife and supplies mysteriously appearing—while the room itself transforms with furniture and even a musical performance. Jim Henson himself makes an uncredited voice cameo as a gorilla in a tutu, adding to its surreal atmosphere.
Despite its limited viewership and obscurity, ‘The Cube’ has been praised for its unsettling tone and thought-provoking content, reminiscent of later series like Black Mirror. It only aired twice and remains available through rare DVD copies and unofficial online uploads, with some versions missing content due to copyright issues.
Why ‘The Cube’ Matters in Television History
This episode is significant because it predates and arguably influences the modern dystopian anthology genre exemplified by Black Mirror. Its experimental storytelling and philosophical questions about reality, consciousness, and control highlight Jim Henson’s willingness to explore darker, more mature themes beyond his well-known puppet work. Recognizing ‘The Cube’ expands understanding of Henson’s creative range and the evolution of speculative television.

Jim Henson’s Experimental Work Prior to Muppets
Jim Henson is best known for creating the Muppets, but before that, he engaged in experimental television projects. ‘The Cube’ was part of Experiment in Television, a series showcasing avant-garde films, plays, and documentaries, including Marshall McLuhan discussing media theory. ‘The Cube’ stands out as a rare glimpse into Henson’s darker, more experimental side, produced during a period of artistic exploration in 1969.
While not widely recognized at the time, the episode has gained attention among fans and scholars for its surreal imagery and existential themes, aligning more with contemporary dystopian narratives than with Henson’s family-friendly work.
“‘The Cube’ is a rare example of Jim Henson’s willingness to venture into experimental, unsettling storytelling that predates similar themes in modern series.”
