->''"One thing's for sure: We're all going to be a lot thinner."''
-->-- '''Han Solo''', ''StarWars: ANewHope''

TheHero finds himself in an empty room, and then the walls start closing in, threatening to squash our hero from the sides.

Like its SisterTrope, DescendingCeiling, The Walls Are Closing In shares many of the same functions and tends to show up in the same situations. This DeathTrap can be decorated with SpikesOfDoom to look even more menacing, and it can be used hand-in-hand with DescendingCeiling on a ConveyorBeltODoom (usually with one coming right after the other in sequence). It may also be subject to a type of a MagicCountdown; no matter how much time the heroes take, the walls are juuust far enough for them to escape, even moving back between shots.

Common ways for heroes to escape this vicious trap is to find a means to brace the moving walls, wait for their {{Sidekick}} to find a way inside and get them out JustInTime before the walls (or spiked walls) would have surely crushed them, or a combination of the two.

This was commonly used as a stock {{Cliffhanger}} in {{Film Serial}}s of the 1940s, and has appeared frequently in such works. If this occurs in a VideoGame, it may be an EscapeSequence.

Compare AdvancingWallOfDoom, when the hero has to outrun a single moving wall; and there may exist some overlap between the two tropes if the DeathTrap is only one moving wall.

See Also SmashingHallwayTrapsOfDoom where a character has to run a gauntlet of smashing objects without getting hit by any.

Not to be confused with DeadlyWalls.

The {{trope name|rs}} was inspired by the pre-chorus lyrics from the Music/LinkinPark song "Crawling."

[[folder: Film]]
* The trash compactor scene in ''[[Film/ANewHope Star Wars: A New Hope]]'' is both a standout depiction of this trope but also a ShoutOut to the [[FilmSerial cliffhanger serials]] that GeorgeLucas would watch as a kid, which very much inspired a lot of the story-telling in the original trilogy. It's also the inspiration for this trope's redirect, TrashCompactorScenario. The ''Star Wars Musical'' even has a whole song about this scene called "[[http://www.infauxmedia.com/the_walls_are_closing_in.htm The Walls are Closing In]]".
* ''Film/{{Krull}}'' includes the [[SpikesOfDoom spiked walls]] version, and a gruesome death for one man who could have escaped but went back for his cherished knife.
* ''[[Franchise/EvilDead Army of Darkness]]'' sees Ash thrown into a pit containing a few demons that he has to fight, as well as this particular DeathTrap just to make things more exciting. He escapes by hanging onto the chain powering the closing walls as it moves up.
* Was invoked in ''[[Film/{{Saw}} Saw V]]''. [[spoiler: Not only does Strahm try and fail to escape by climbing up to the ceiling, but the scene rather graphically shows the perils of trying to "brace yourself" to stop the walls as the bones splinter out of his limbs. In ''Saw VI'', Hoffman retracts the walls and looks over what's left of Strahm. It's really not a pretty sight. WordOfGod stated that, when they made the trap, they made it with showing just how graphic it could ''really'' get.]]
* The 2007 Spanish film ''Film/FermatsRoom'' featured this, with the twist that the victims had to correctly answer logic or math puzzles to stop the walls from advancing.
* In the 1946 film, ''Strangler's Morgue'' ([-AKA-] ''The Curse of the Wraydons''), the murderer Philip Wraydon is crushed by the converging walls he has set in motion to crush the hero, Jack Wraydon.
* There's a non-lethal parody in ''Film/{{Toys}}'', where RobinWilliams's character and others find themselves in a room that keeps getting smaller as square sections of wall close in one at a time. It's meant to convey that General Leland is expanding other areas of the toy factory for his own [[EvilPlan nefarious purposes]].
* Another non-lethal parody in ''ErnestScaredStupid'' when Ernest fell in the garbage truck and his dog activated the compactor. Ernest tries to keep the walls from closing in and even removing the batteries fails. He gets rescued trapped in compacted garbage.
* ''Film/BloodSuckingPharaohsInPittsburgh'': [[spoiler:Grace]] tries to kill [[spoiler:Deedee]] in a trash compactor but winds up caught in it, instead.
* ''Film/{{Superman}}'' offers a variant in the subway tunnel where Luther keeps his hideout: a section of platform wall that pushes outward suddenly, shoving a police detective into the path of an oncoming train.
* ''Film/TheRaven1935'' has a TortureCellar with one such room.
[[/folder]]

[[folder: Literature]]
* OlderThanRadio: The archetype is EdgarAllanPoe's "Literature/ThePitAndThePendulum" (1842), in which the moving walls are red hot and push the victim into the pit.
* There are a number of callbacks to the trash compactor scene in the StarWarsExpandedUniverse. In ''TheThrawnTrilogy'', Luke heads into one and as the walls close in he hopes that Mara, who is controlling the trash compactor and previously stated her desire to kill him, won't let her hatred overcome her. She stops the walls a meter apart, and he rock-chimneys up and saves her boss.
* In ''Secret of the Sixth Magic'' by Creator/LyndonHardy, debtors in the city of Pluton are condemned to death if no one will pay off their creditors to buy them as slaves. This being a fantasy world, the method of execution is magic-powered: they're sealed inside an unbreakable cube, which then magically gets [[{{Claustrophobia}} smaller... and smaller]]... and [[LudicrousGibs smaller]].
* The ''{{Goosebumps}}'' book ''One Day At Horrorland'' features a house of mirrors that ends in a room where this happens. The floor drops out at the very last second.
* ''Literature/{{Animorphs}}'' used this in "The Separation". Visser Three used a moving wall because he thought the group were Andalites, who hate enclosed spaces.
* Literature/AlexRider, in ''Stormbreaker'', gets trapped in a car inside a crusher in a junkyard. He's able to squeeze out the window and climb out.
[[/folder]]


[[folder: Live Action TV]]
* {{Lampshade|Hanging}}d in ''Series/{{Dracula}}: The Series''. The heroes stumble into the [[SpikesOfDoom spiky version]] of one of these while sneaking around [[{{Dracula}} Alexander]] [[SdrawkcabName Lucard]]'s castle, and escape because one of them had seen how to defeat it [[SawItInAMovieOnce in an old movie]]. Later on, Dracula is showing an ''invited'' guest around the place, they come to the (now empty) trap, and he says something like "Do you like it? I saw it in an old movie, and I just had to have one!"
* ''Series/TheAdventuresOfSuperman'':
** Superman, Lois & Jimmy are trapped in a concrete bunker, with Supes out of commission due to a Kryptonite ray. Then the walls start closing in. Luckily there [[ChekhovsGun happened to be]] a discussion of hypnotism earlier in the episode. Superman hypnotises Lois, which [[HandWave somehow]] makes him able to levitate her. Her body stops the walls, and Jimmy is able to climb up to the top and redirect the Kryptonite ray.
** In "[[Recap/TheAdventuresOfSupermanS1E18DrumsOfDeath Drums of Death]]", the VillainOfTheWeek tries to use a wine press to dispose of Perry, Perry's sister, and Jimmy. Superman arrived and tore apart the bars, allowing them to escape.
* ''Series/{{Batman}}'' (the 1966 TV series): In Catwoman's first appearance, she subjects Batman & Robin to the SpikesOfDoom version (see picture at top of page). But the walls stop just before they'd impale Batman, and anyway the spikes are made of rubber. She was just toying with him. (It wasn't the {{Cliffhanger}} of the episode.)
** This was an homage to an [[http://img-fotki.yandex.ru/get/6601/38423963.37/0_a6f9b_3b88d32_XL.jpg actual cliffhanger]] from the [[Film/TheBatman 1943 Batman serial]].
* ''Series/RoboCopTheSeries'' placed the title character in a trash compactor. [[ArtisticLicensePhysics When air pressure almost reached 2000 PSI]], a flashback gives Robocop inspiration, [[BackFromTheBrink allowing him to push back the walls]].
* ''Series/EstateOfPanic'' played with this trope in the trash compactor, the study (along with a DescendingCeiling), and the wine cellar (coupled with SpikesOfDoom).
* One episode of ''The PaulHogan Show'' featured a series of sketches in which someone is murdering Australia's greatest sporting stars. Squash player Geoff Hunt was killed when the murderer slowly cranked in the walls of his squash court, causing him to be crushed.
* ''Series/DoctorWho'', "[[Recap/DoctorWhoS6E7TheWarGames The War Games]]". Like the TARDIS, the villains' [[SdrawkcabName SIDRAT]]s are bigger inside than out. But if necessary, the interior can be made to shrink, invoking this trope on anybody inside.
* ''Series/KamenRiderGaim'': [[spoiler:Sid[=/=]Kamen Rider Sigurd]] is killed when Roshuo, leader of the Inves uses telekinesis to turn a solid cliff face into one of these.
* ''Series/{{CSINY}}'': In "Death House" the team are investigating a penthouse that has been converted into a series of elaborate deathtraps. Hawkes gets trapped in a small metal room where the walls start closing in on him.
[[/folder]]

[[folder: Music Video]]
* {{Music/The Cardigans}}' video for "Erase/Rewind" shows the band in such a room, and is blatantly inspired by ''Franchise/StarWars''. It has two versions: the [[http://www.youtube.com/watch?v=x9ZwORlV4GE original one]] with the DownerEnding, and the [[http://www.youtube.com/watch?v=ASTxThbqfk0 13th floor edition]] where they save themselves (it's named because it has additional scenes from the movie ''13thFloor'', which the song was used in).
[[/folder]]

[[folder:Pinball]]
* The "Strait Jacket Escape" illusion in ''Pinball/TheatreOfMagic'' requires the magician to escape while trapped between [[SpikesOfDoom two spiked walls]] closing together.
[[/folder]]

[[folder:Puppet Shows]]
* Although it was never shown in the series itself due to [[SpecialEffectFailure the limitations of puppets]], one of the paintings forming the backdrop to the ClosingCredits of ''Series/CaptainScarletAndTheMysterons'' showed the title hero desperately running through an ever-narrowing spiked corridor.
[[/folder]]

[[folder:Video Games]]
* Most late-model ''Franchise/FinalFantasy'' games have this trope, sometimes with only one moving wall in the DeathTrap. The wall is a living creature, and must be defeated before it crushes the party.
** ''VideoGame/FinalFantasyIV'' has a bad guy trapping the heroes in one of these during a {{cutscene}} as they try to escape his lair after taking him out. Palom and Porom, the two cute kid mages, [[HeroicSacrifice sacrifice themselves to save the others]] by turning themselves to stone and stopping the walls.
** And another sequence where the moving wall was alive and you actually had to fight it to the death as it advanced. If it advanced all the way, your party members would start dying instantly one by one, and significantly faster than you could revive them.
** ''VideoGame/FinalFantasyXII'' has two Demon Wall enemies. The first one you fight presents a twist -- it is powered up and offers you little time to defeat it, but it is fortunately a SkippableBoss and you are meant to flee the battle by using the door that it would crush you against, and instead fight the second wall in the next room. The second one (the one you ''must'' defeat) is much weaker and offers much more time to win. If so desired, you can come back later in the game to rematch against the first wall. Unless you've done a lot of LevelGrinding, in which case you can just off the first one right away and pick up a weapon that you're not intended to have at that point in the game yet (still not quite the InfinityPlusOneSword though, but it is one of the games many, many {{Disc One Nuke}}s).
* In ''VideoGame/HalfLife1'', a pair of {{mooks}} capture the player character and toss him in a trash compactor. Which he then escapes via conveniently stacked up garbage.
** The ExpansionPack ''Opposing Force'' has a trash compactor that looks even ''more'' like the ''StarWars'' one.
* In ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' there's a room in Shadow Temple where rickety wooden [[SpikesOfDoom spike-walls]] slowly close in on you. [[spoiler:No worries here, though: if you have Din's Fire, you'll be fine.]]
** One dungeon in the [[VideoGame/TheLegendOfZeldaOracleGames Oracle series]] has a large room with obstacles that must be crossed before its walls crush the player.
* Used to chilling effect in ''NightmareHouse''. You're trapped in a doorless corridor and every time you cross the room and turn around the other wall is closer than it was the last time you looked at it. The only way to get out is [[spoiler: to keep doing it until the walls close in completely. Then you wake up somewhere else.]]
* ''VideoGame/MegaMan 4'' has the series' first example with Dust Man's trash compactor stage.
** In ''VideoGame/MegaManZero'', Aztec Falcon was fought in a trash compactor stage as well. It's different in the fact that you weren't the one being crushed, it was another Reploid. And you only had 75 seconds to beat the guy.
** ''VideoGame/MegaManX 2'' has several sequences where you have to climb up between walls before they crush you. There's actually a robot who triggers this; if you kill it first (try charged-up Sonic Slicer), the walls won't move. Alas, there's no such trick for the similar traps in ''X3'' and ''X7''.
** ''X4'' has one in the ''opening stage'', which you could accidentally drop down right before the boss fight. It does contain a life and a health pickup, though.
* Adam Cadre's ''Lock and Key'' game about designing a foolproof dungeon includes this trap. If you add the SpikesOfDoom, it turns out they were poorly made and hit each other, breaking the trap and allowing the prisoner to simply climb past.
* In ''VideoGame/{{Messiah}}'', a shooter from 2000, there is that moment, where you trigger a security system, which causes the only available NPC (a worker) to fall and break his legs (meaning he can only crawl slowly), and one of the walls begins to slowly move against you. You're then required to possess the worker and ''slowly crawl to the switch'', deactivating the wall and opening a passage further.
* ''VideoGame/PrinceOfPersia2'' has crushing walls in its later levels, some of which are situated in inescapable pits under {{Fake Platform}}s.
** Newer ''Franchise/PrinceOfPersia'' games on some occasions feature the inverse: a tall narrow well that has to be navigated by jumping from one wall to another. And it has to be navigated fast, because on of the walls is moving ''out'', making it too wide to jump across and introducing the Prince to a lethal fall down.
* ''VideoGame/RiseOfTheTriad'': In early versions, [[DeadlyWalls even touching an approaching wall causes instant death]]. While walls usually were independent movers, there are some places where sections of walls move back and forth to crush the player and one level where it appears the walls are closing in when you hit a touchplate but stop at the last second.
* In the [[VideoGame/HarryPotter PC game version]] of ''Literature/HarryPotterAndTheChamberOfSecrets'', there is an obstacle course you have to pass through to reach the title location. One of the obstacles is a room with walls which close in on you, although you rather boringly beat them by simply running through the room fast enough.
* Happens throughout the ''Franchise/TombRaider'' series.
* Appears in ''VideoGame/DistortedTravesty'' where [[spoiler: The Artist tries this to kill Jerry after he sides with The Darkness.]]
* The first ''VideoGame/GodOfWar'' has a variant in that one wall moves, except it wouldn't hurt Kratos like an AdvancingWallOfDoom but would crush him against the magic enemy barrier if the player didn't kill all the {{Mooks}} fast enough. The second game plays this straight with two walls.
* Happens at the beginning of the last mission in ''RatchetAndClankFutureACrackInTime'', but Qwark can brace the walls forever, and all you have to do is just blow up some {{Mooks}} in the enclosed space before the trap is released.
* In ''VideoGame/CaveStory'', the walls of Ballos' chamber close in when the hero and Curly Brace defeat him for good. [[spoiler:They would be crushed if not for Balrog.]]
* In ''VideoGame/{{Portal 2}}'', prior to the DiscOneFinalBoss, you [[StupidityIsTheOnlyOption have no choice but]] to jump into an ObviousTrap, leading to this. However, the walls are not intended to crush you but rather to force you into position over a TrapDoor as part of a larger trap.
* In ''VideoGame/BreathOfFire2'', the party is nearly killed by such a trap. Rand holds the walls apart long enough for the rest of the party to escape, but he soon finds his strength fading...[[spoiler:his mother Daisy finds him and pushes him out of the trap, taking his place and sacrificing herself. Rand watches helplessly as his mother is crushed between the walls.]]
* The deathtrap is featured in ''Rise of Nightmares'' for the Xbox 360 Kinect. Two people find themselves crushed in it.
* The NES game ''VideoGame/{{Nightshade}}'' used death traps as "lives". The second one was walls closing in.
* The second planet encountered in [[ShiftingSandLand "Slipsand Galaxy"]] from ''VideoGame/SuperMarioGalaxy2'' had several walls that slid toward and away from each other.
** The last planet encountered in "Bowser's Galaxy Generator" before the final battle with {{B|igBad}}owser involved Mario and Yoshi eating Dash Peppers to run through a hallway lined with walls of magma before they close in on them.
* This also happens in the fight against Roy Koopa in ''VideoGame/SuperMarioWorld''. The most immediate danger is not that the walls will crush you, but that there is less and less room for Mario to evade Roy's attacks.
* The Waste Disposal area in the ''KingdomOfLoathing'' "Bugbear Invasion" challenge path, as an extended Star Wars homage, has these, and frequently warns you that the walls are coming closer. Unlike some of the game's warnings of this nature, these are not a case of TakeYourTime - if you don't solve the area's puzzle in time, you are crushed and subjected to the game's death penalty.
* The very first scene from the Famicom Disk System game ''Dead Zone'' takes place in a trash compactor (with bits and pieces of broken robots strewn all over the floor) and then the walls start closing in after several proper commands have been given. When the player uses the move command (kanji: ウエ) several times and the screen changes to the compactor's ceiling, the player must get out by opening the grate on the ceiling before he is crushed.
* ''VideoGame/NancyDrew: The Silent Spy'' has Nancy and [[spoiler:Zoe Wolfe]] stuck in a trash compactor. The player has to solve a puzzle to free the lock.
* ''VideoGame/ThyDungeonman 3'' has walls of {{spikes|OfDoom}} that smash the character if they are not stopped [[spoiler:with the convenient bone lying around]] before 12 turns have elapsed.
* ''Squeeze Box'' for the UsefulNotes/{{Atari 2600}} has the player shooting at bricks in the wall to stop them from advancing towards him while trying to escape.
* [[Creator/MidwayGames Bally/Midway's]] arcade ''{{VideoGame/TRON}}'' video game has the player shooting Tron's disc at a wall that descends towards him so he could enter the MCP before he gets derezzed.

[[folder:Web Comics]]
* In ''Webcomic/{{Narbonic}}'', when Mell is sent on a mission to kill [[spoiler:Helen Narbon (the elder)]], she falls prey to this after commenting, "Huh, weird floor." Her captor comments that there [[http://www.webcomicsnation.com/shaenongarrity/narbonic/series.php?view=archive&chapter=10251&name=narbonic wasn't time to come up with something original]], since Mell made it farther than expected.
* Appears in the Maze of Many in ''Webcomic/{{Goblins}}''. Ends up killing [[spoiler:Barbarian Kin and Forgath. Barbarian Minmax died earlier from a [[DescendingCeiling Descending Door.]]]]
[[/folder]]

[[folder:Western Animation]]
* There's a visually similar scene in ''TheIncredibles'', as Mr. Incredible races to get out from between two closing walls of lava.
* ''All New {{Popeye}} Hour'': Popeye and his friends are trapped in a pit with the walls closing in. Desperately, Popeye throws his can of spinach to jam in the edge of the walls on top. The walls crush the can, causing the spinach to fall into Popeye's mouth. Now strong to the finish, Popeye easily forces the walls back and the gang escapes.
* In an episode of ''WesternAnimation/TheSimpsons'' spoofing the story of Moses, Milhouse and Lisa (as Moses and Aaron) are thrown in a room with [[SpikesOfDoom spiked]] walls that close in on them. However, the spikes have all been installed opposite each other, so that the walls stop when the tips touch, leaving plenty of room for them to climb to safety (and for Lise to remark, "Eh, slave labor. YouGetWhatYouPayFor.").
* An episode of ''WesternAnimation/{{Ducktales}}'' had Scrooge and his nephews trapped in an Egyptian tomb with a wall with spears closing in on them. They're saved by pressing a hidden (belly) button activating a trapdoor.
* [[LampshadeHanging Lampshaded]] in ''WesternAnimation/TheVentureBrothers'':
-->'''Doctor Orpheus:''' Spiked walls? How fast?
-->'''Doctor Venture:''' Uh, slower than "haunted house" spiked walls but not quite as slow as "mad scientist" spiked walls.
* In ''ScoobyDoo'', the gang discover a locked trap door and an nearby organ that appears to control it. Scooby offers to play it see if they can open the trapdoor, but when that happens, the gang realizes the walls are closing in on them. As the gang tries to hold them back, Scooby desperately plays the instrument more, and then frantically dances on the keys to try to get it to stop the walls, and succeeds by sheer luck.
* Happened in the 1987 ''WesternAnimation/{{Teenage Mutant Ninja Turtles|1987}}'' episode "Michelangelo, the Sacred Turtle" when Michelangelo and the servants fell in the trapdoor and the walls are closing in. They're saved by solving the hieroglyphs.
* [[spoiler: Blurr]] falls victim to one of these in the first episode of the third season of ''TransformersAnimated''. Sadly, [[spoiler: he is turned into a cube.]]
* Bruce Banner is stuck in one of these in the opening theme to the 80's ''IncredibleHulk'' cartoon series.
* ''IceAge'' did this with a glacier.
* InspectorGadget was caught in a death trap of this type at least twice, one involving SpikesOfDoom.
* Spoofed in a ''WesternAnimation/KappaMikey'' cutaway. It is a direct parody of the scene in ''Star Wars'', with Guano dressed as a Storm Trooper.
* Along with SpikesOfDoom on ''TUFFPuppy''.
* In ''ScoobyDooAndTheReluctantWerewolf'', Scobby, Shaggy and the others get trapped in chamber with SpikesOfDoom when they attempt to flee Dracula's castle.
* In one episode of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Daring Do (Rainbow Dash's favorite action hero) is placed a room with this trap... [[ThereIsNoKillLikeOverkill along with spiders, snakes, and quicksand.]]
* ''WesternAnimation/DangerMouse:'' episode 3 of "The Duel" has DM and Penfold in a room at an amusement park with the spiked walls closing in on them. DM stops them with a giant spanner Penfold had on his person.
* In an episode of ''WesternAnimation/TheAdventuresOfMrT'', a couple of the gymnast kids get stuck in one such deathtrap. They escape by bracing the walls with broken wooden table legs, fashioned as improvised uneven bars, and use them to reach a vent at the top (and very middle) of the room.
* ''WesternAnimation/AdventureTime'': Happens with the first room Ice King, N.E.P.T.R., Tree Trunks, Shelby and Lemongrab find themselves trapped in in "Mystery Dungeon".
