* A key plot point to ''Franchise/AttackOnTitan'' at the end of the first major story arc/season was the revelation that inside the walls of Paradis Island were [[spoiler:Colossus Titans]].
* In ''Manga/MyLovelyGhostKana'', Kana sometimes hides herself inside a wall when she doesn't want to talk to Daikichi. Being a ghost, it's much easier for her.

* The third act of ''WesternAnimation/{{Encanto}}'' reveals that [[spoiler:Bruno]] never left the village, but instead has been living within the walls of Casita. He's been secretly [[spoiler:patching up the cracks]] that appear to try and help his family the best he can. It's a JustifiedTrope as Casita is a magical building with a number of BiggerOnTheInside rooms, spaces between walls included.

* In ''Film/Stowaway2021'', Michael, who was doing maintenance work on the ship before launch, is stuck behind a service panel. When he is discovered, they are on the way to Mars with no way to turn around.
* Used as a method of killing in ''Film/WalledIn'' as an architect named Joseph Malestrazza imprisons innocent people (including children) between the four walls of confined spaces that are actually hollow building columns that are about to be filled with cement.

* In "Hotel World" by Scottish author Ali Smith, a woman working in a hotel sits on a room service trolley and has her friend push her around on it. After she's pushed with too much force, she crashes into a wall and breaks through. Behind the wall was actually an old elevator shaft, and she falls to her death.
* In ''Literature/LordsOfTheStarship'' a giant starship is being built over hundreds of years. The builders have divided in two; the Technos (aristocrats) and the People (workers). A war breaks out between them -- the ship is big enough to have tank battles in the corridors. Finally, the victorious People seal up the tunnels where the Technos are still resisting. Years later, it is said you can hear the ghostly hammering of the Technos slowly starving to death within the walls.
* The Opera House secret passageways in ''Literature/{{Maskerade}}'' turn out not to be anything as romantic as a secretly built web of tunnels, and are instead forgotten hallways long since partitioned off.

* In the YA novel "Behind the Bedroom Wall," a thirteen-year-old German girl named Korrina notices strange noises behind the wall in her bedroom, though her parents insist everything is fine and she's imagining it... because they're hiding a Jewish family inside the walls while they prepare to move them to the next safe point.
* In ''Literature/TheMagiciansNephew,'' Polly Plummer discovers a door in her attic which leads to a tunnel that presumably connects all the houses in the row. At the very least, it connects to her best friend's uncle's forbidden study...

* One episode of ''Series/{{Columbo}}'' has the murderer hide the victim's body inside a bathroom wall while his mansion is undergoing renovations. The body was first put inside a garment bag meant for fur coats to prevent the smell of decay from escaping. The bag was added to a space near the shower stall, likely meant for plumbing and drainage pipes, then hidden behind fiberglas insulation. The workmen suspected nothing, and continued to plaster and tile the walls.
* In the ''Series/CSICrimeSceneInvestigation'' episode "Stealing Home", the CSI team find a dead body in a wall inside the title home which has been stolen and brought into the desert, with the autopsy revealing that said body has been there for twenty years. [[spoiler:DNA testing eventually reveals that it was a handyman who had an affair with the wife of the homeowner, fathering the [[OnlySaneMan only sane member]] of the rather dysfunctional family who owns the house before being murdered and walled in by said homeowner, who then fled and became a DisappearedDad.]]
* Used for RuleOfFunny in ''Series/DangerFive'' when our heroes realise: "My God. There's Nazis in the walls!" Despite it being the walls of a bank vault.

* In the first season of ''Series/PrisonBreak''; a large part of Scofield's elaborate plan for breaking his brother and himself out of prison involves getting into the spaces between the walls of the prison and using them to move about the building while supposedly locked in his cell. Scofield does this via the panel that holds up [[BathroomBreakOut the cell's sink and toilet]].
* A RunningGag in the 2021 season of ''Series/TheWeeklyWithCharliePickering'' was Zoë Coombs Marr being fired after her first episode, but refusing to leave. A later episode reveals that she is living in the walls of the studio.

* "Woman in the Wall" by Music/TheBeautifulSouth is about an alcoholic who kills his wife in a drunken rage and hides her body in the walls of their house, but is tormented by hearing her voice from the walls every night.
* The third verse of the Creator/ShelSilverstein song "You're Always Welcome At Our House" mentions the family sealing a child in the wall of their basement when they invited him into their house after he came to retrieve his ball.

* There are passages you go through in ''VideoGame/ResidentEvil7Biohazard'' by shimmying between the walls in both the Baker's main house and in the decrepit Old House. The former is noteworthy for being the first time you're able to fully give [[ImplacableMan Jack]] the slip for an appreciable stretch of gameplay (since he can't fit inside to follow you), while the latter is memorable for being infested with what seems like hundreds of centipedes, causing Ethan to drop a ClusterFBomb as they crawl over him.

* While ''VideoGame/TheSeventhGuest'' had surreal secret passages in the Stauf Mansion, the sequel, ''The 11th Hour'' amounts to Carl Denning moving between the walls of the house. Barrels and other junk can sometimes be found in them.

** "[[Recap/TheSimpsonsS7E6TreehouseOfHorrorVI Treehouse of Horror VI]]": In the segment "Homer³", Patty and Selma are coming over and Homer tries to find a place to hide. He finds a spot behind the bookcase, but ends up going through a portal in the wall. He ends up in a 3D world with an ArtShift, but can still be heard calling out from beyond. At first everyone believes he is inside the wall, until Professor Frink explains Homer's situation. The Inside a Wall trope is somewhat subverted here.

** A running gag has shots that pan from one room to another cut through walls or floors to show items and creatures inside of them that really shouldn't be there. Residents of the Simpsons family's intramurary spaces seen this way include blocks of asbetos, piles of treasure, an active tape recorder with a microphone, wiretaps from assorted government agencies (and the KGB), the family cat, hatching dinosaur eggs, dancing mice, the skeletal remains of Santa's elves, and the fish-man from ''Film/TheShapeOfWater''. A shot in the elementary school also shows a living rattlesnake in its floorspaces.
