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

Did You Know?


Although this film completely lacks the puppets that are usually associated with Jim Henson, several scenes utilize cutting-edge (at the time) chromakey video compositing, one of the technologies which Henson would later use to allow his Muppets to accomplish the "impossible". See more »


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 ...

My first exposure to absurdist theatre.....
30 September 2008 | by (United States) – See all my reviews

I was 12 when I stumbled on this show one Sunday morning - and I think it permanently Warped My Mind. I'm pretty sure it was my first exposure to absurdism, if you don't count MAD Magazine... I never forgot the show, and for years afterwards I tried to find more info about it. What a thrill to stumble on Wikipedia's entry,which had a link to the full video... and I did *not* know till just now about Henson's role in the production! One can see the roots of many future TV and movie productions here - from THE PRISONER to THE MATRIX to THE TRUMAN SHOW. And considering the times, the production effects and editing are simple yet sophisticated, perfect usages of the possibilities of the medium. A crucial piece of TV history... Be sure to let your preadolescent or adolescent child watch this thing, it'll prepare them nicely for the absurdity to come...!
