A man awakens inside a white cube, covered in a four-by-four grid. He has no memory of how he got there and there seems no way out. But as time passes, panels open temporarily to admit an intruder or onlooker. They pop back through their panels but bar the man from going through, pointing out "this is MY door; you'll have to find YOUR door." The intruders vary from individuals to a child on a tricycle and and a rock band. More and more people start to come into the cube, filling it up and this developes into a sort of cocktail party. A rock band comes through sometime during all of this, singing The Cube's theme song, "You'll never get out, you'll never get out, you'll never get out till you die." At one point the man sees himself, a double, and has a dialog with himself about how he has to find HIS way out. Is the man a prisoner? An inmate? Someone on a voluntary retreat? The stories change with each new visitor. Eventually, just as he succumbs to despair, a square panel clicks open.... Written by David E. Martin and friends

Professor: [clears throat] Excuse me, I know this is, well, a bad time but I just wanted to congratulate you and shake your hand.
The Man in the Cube: Oh? On what?
Professor: Well, as I interpret what you're doing here, this is all a very complex discussion of, eh, Reality versus Illusion. The perfect subject for the television medium!
The Man in the Cube: What do you mean, television?
Professor: Well, this is a television play.
The Man in the Cube: [scoffs] What?
Professor: Oh, you don't believe that?
The Man in the Cube: Of course not!
Professor: I should have thought you'd want to. After all, there's only one other possible ...

THE CUBE: A long-lost "Experiment in Television" and a place to discuss it
14 January 2003 | by davidemartinSee all my reviews

On February 23,1969, a Sunday afternoon, the anthology show NBC EXPERIMENT IN TELEVISION aired a one-hour teleplay by Jim Henson, then best known for being the man behind "Ralph the Dog" on the JIMMY DEAN SHOW. This unique film, titled simply THE CUBE, starred Richard Schaal as a man trapped in a white cubical room. He had no idea how he got there or where it was. And although anyone could enter, he couldn't leave....

In 2002 I posted the original IMDb comment on THE CUBE and started the long struggle to expand the credits on this long-lost, long-forgotten classic. Soon other IMDb users were regaining their memories of this odd but invasive show. After a few months of this it seemed a good idea to create a common place to share thoughts, memories, and discoveries about THE CUBE.

And another place online where you can show people and go AH-HAH! SEE! I TOLD YOU IT EXISTED!!!!

In the three years of existence, we've gone from the barest of information online to full cast lists and a reconstructed script. Next, actual screen images from THE CUBE. Come join us! Feel free to add anything you want, anything you can find, from personal thoughts to actual files and images!

-------Postscript, 29July2008------- Six years later and we've accomplished much of our goals. The biggest success was bringing out of hiding both BW and COLOR copies of this lost masterpiece. Those copies are now available online, both for free and in the form of pirate copies others have made. We're still hoping that Henson's kids will bring out a legit, newly-remastered edition.... In the mean time, we've reconstructed the original script, collected a mass of screen caps, and seen the creation of TWO stage versions (one in US, one in Germany).
