'''''The Cube''''' was an hour-long teleplay that aired on NBC's weekly show ''NBC Experiment in Television'' on February 23, 1969. The production was produced and directed by puppeteer JimHenson, the screenplay co-written by long-time Muppet writer Jerry Juhl (who also appears in a cameo).

The story follows Richard Schaal as a man trapped in a cubical white room that anyone else could enter and leave, but which he himself apparently could not leave. The main character, simply named The Man in The Cube, is subjected to an increasingly puzzling and frustrating series of encounters as a variety of people come through various hidden doors. But as many remind him, he can only leave through his own door, so he must find it.

Not to be confused with ''Film/{{Cube}}''.

!!Tropes associated with this work:

* AlienBlood: [[spoiler: The protagonist cuts himself and tastes his own blood. It's Strawberry Jam.]]
* AndIMustScream: [[spoiler: One possible interpretation of the ending -- the man will be stuck in the Cube being tormented by his visitors until the end of time.]]
* ArcWords: Strawberry jam.
* BlackBugRoom: [[spoiler: The titular cube is implied to be this.]]
* BrokenRecord: Happens to a live rock band.
* TheCameo:
** Muppet performer Jerry Nelson appears on-screen as a monk.
** While the Man is being shown the end of the teleplay on a TV set, we see the names of both Joe Raposo (one of ''SesameStreet'' 's songwriters and music composers) and Don Sahlin (Jim Henson's original Muppet builder) scroll during the closing credits. Neither of them actually worked on the actual special, though.
* CuckooNest
* DiabolusExMachina: [[spoiler:The man finds out in the last minute that his escape was an illusion and he's still in the cube]].
* DrivenToMadness: The man is constantly in danger of losing his sanity.
* DrivenToSuicide: The man tries to commit suicide by the end, but the gun he's provided with just squirts ink at his head, upon which every character seen so far all show up and laugh at him.
* EpiphanicPrison: The only way out is to figure out what the cube is all about. (Maybe.)
* EverythingIsRacist: Invoked with one visitor, who is black, and expresses that he liked the Cube very much, and even has one of his own, but there is one problem he has with it: it's all ''white''.
* FourthWallObserver: One visitor is a film critic who tells the man that he's just a character in a teleplay, and produces a TV to show him the ending.
* GoshDangItToHeck: Completely subverted, which is odd, given that this was still a couple of years or so before [[TheRuralPurge edgier television programming was the norm]]. "Hell" and "damn" are spoken.
* GroundhogDayLoop: [[spoiler:Implied by the strawberry jam on the stool, which is the same stool that the man broke the Ramadar with.]]
* {{Gaslighting}}: Furniture appears and disappears when the man's back is turned suggesting they are being moved when he's not looking. Of course it could just be his mind.
* HappyEnding: {{Discussed}} and subverted. The film critic shows the man the play's ending in advance -- the man's healthy, happy, and even got the girl... but he's still in the cube. And to top it off, he doesn't actually want the girl. [[spoiler:The play eventually ends on a cruel note, with the man escaping the cube only to find himself back inside just before the credits roll.]]
* HeAlsoDid: Yes, this is the same JimHenson who made TheMuppetShow.
* HopeSpot: The Man comes very close to going crazy, but in the end, [[spoiler:he appears to leave The Cube through a door, only to be lead to a completely different room which turns out to ''also'' be The Cube.]]
* IceCreamKoan: Said by the monk. "All is all. What is, is."
* MentalWorld: Suggested by the film critic, and also by the band's opening verse, "You're really in the middle of the inside of yourself".
* MindScrew: For both the man and the viewer. Who is the man? What is the cube, and why is he in it?
* MonsterClown: Two comedians with clown make-up who like everybody else in the film are menacing, unsettling and malicious.
* MoodWhiplash: Used by the 'people' as a jarring a effect to further fluster and confuse the Man in The Cube.
* OnlySaneMan: The Man in The Cube, at we seem to think so until the MindScrew kicks in both in-universe and out.
* OntologicalMystery
* NoNameGiven: The character. One visitor calls him "Ted", a name he denies is his.
* PuttingOnTheReich: The two Munich police officers, who seem to be wearing altered SS uniforms.
* SanitySlippage
* SealedRoomInTheMiddleOfNowhere
* SelfInflictedHell: Hypothesized by an old man.
* ShapeShifter: One of the visitors drops in on the man, at first, looking like a beautiful young lady, but as she converses with him about you can trust nobody, because no one out there are what they seem, she shifts more and more into a hideous old crone.
* SinisterGeometry
* TomatoInTheMirror: "I'm... projected."
* TemptingFate: Near the end, the Manager opens a door and tells him he can leave, and the man refuses to believe it isn't yet another trick.
-->'''Man:''' "How about this one? The minute I set foot outside this door, two gorillas grab me, dressed in ballet costumes, drag me back in, throw me on the floor and surround me singing Home Sweet Home!"

* UnreliableExpositor: Pretty much ''everyone'', given how they all contradict each other.
* WeirdnessMagnet: The protagonist is not given any time between strange encounter after strange encounter, just to make matters worse for him.
* WhiteVoidRoom
* YouWakeUpInARoom: Actually, it's never shown what the character was doing before he appeared in the cube. In the end, [[spoiler:it seems he only exists inside of the cube.]]
