Paranormal Productions is the movie studio-themed eighth floor of The Last Resort in Luigi's Mansion 3. It is accessible after obtaining the elevator button from Dr. Potter in the Garden Suites. When Luigi arrives here, the door that leads backstage is locked, so Luigi must go to the Studio Entrance and activate a TV, which he can use to warp to another TV in the Elevator Hall where he can get the key. Backstage, Luigi finds the ninth floor's elevator button being held by a director ghost named Morty, who is upset because his megaphone is missing.
There are four movie sets that Luigi can explore at this time. Each set has a TV that links to another one backstage when activated. Each set also has a camera which, when Luigi uses it, turns the area in front of the camera into a movie. If Gooigi in the area in front of the camera, he will become part of the movie. This mechanic is the core of the puzzles that Luigi and Gooigi must solve to return Morty's megaphone and get the elevator button. After obtaining the floor's elevator button, the cameras can no longer be used.
Once all four TVs are activated, Luigi needs to take a bucket to the Horror Set and place it in the well. With Gooigi by the well, Luigi must turn the camera on and wait for a human-like puppet to rise from the well with the bucket full of water. The bucket of water needs to be taken to the Castle Set. When the camera is turned on, a rock will be catapulted onto a cart, revealing a sprout that can be watered to reach the top of a tower, where Gooigi can obtain a torch. However, he is attacked by Goobs with swords and shields, and Luigi cannot end the movie until they are defeated. With the Goobs gone, Luigi can take the torch to the Fire Set. This set features a town that becomes ablaze when the camera is on. Firefighter Goobs and a Hammer with a siren on its head will appear, and they must be captured before the movie can end. Once that's done, the torch can be lit and taken to the Micro Set. This set has a cardboard box which turns large when the camera is on. Upon using the Suction Shot to open the box, a model of a giant spider comes out. Inside the box are multiple Gold Spiders and Morty's megaphone attached to a web. The web can be burned with the torch, allowing Luigi to take the megaphone back to Morty.
When Morty gets his megaphone back, he decides that he wants to Luigi to star in his latest movie. He opens the way to the City Set, a tiny model of a city that makes Luigi seem giant, then summons a Goob in a fire-breathing monster suit to fight Luigi, filming the entire thing. Once Luigi defeats the Goob, Morty finishes filming and gives Luigi the elevator button, then heads for the Editing Room. Optionally, Luigi can follow Morty into the editing room and capture him. If he leaves the floor and returns, however, he can run the film reel and watch the edited footage of his City Set fight. When Luigi tries to bring the button back to the elevator, Polterkitty steals it, forcing Luigi to chase her down to get it back.
