Trivia: Denise Richards as a kid tells the boy that she'd rather be boiled alive than dance with him. She dies precisely that way later in the movie.
Trivia: Mr. Tuttle is also the name of the housekeeper from another haunted-house movie, "The Changeling" (1960).
Trivia: The scenes with the flying dinosaurs were supposed to be in the original movie, as it was part of the book Jurassic Park, but Spielberg decided not to include this in the first movie due to budget restraints.
Trivia: In the final shot, the Creeper's eye looking through one of the holes of dead Darry is Justin Long's eye. (Confirmed on the DVD commentary).
Trivia: Eric Stoltz was nearly cast for the role of "Rusty Nail", but director John Dahl felt Stoltz didn't sound scary and intense enough so the part was given to Dahl's first choice, Ted Levine.
Trivia: The only film role of Shawna Loyer, who portrays the "Angry Princess." Because of the character's constant nudity, and the role being Loyer's only credited on-screen performance, for many years, it was believed that Loyer was actually a pornographic actress working under a pseudonym. This rumor was further fueled by the later production of "13 Erotic Ghosts," a porn parody of the film, as people speculated Loyer was also one of the actresses who appeared in it. The rumors have since been disproved. Loyer is not a porn-star working under a pseudonym, nor did she appear in the porn parody.
Trivia: The woman who accidentally calls Burt Gummer (Michael Gross) "Mr. Goober" is actually played by Michael Gross' sister Mary. Like her brother, she's an actress who was a co-star on Saturday Night Live for several years in the 80's, and has done a smattering of film, television and voice-acting roles since.
Trivia: Reportedly, the film was originally going to be titled "Escape from Mars," and was going to be a sequel to "Escape from New York" and "Escape from LA," with Kurt Russell reprising his role as Snake Pliskin. However, after "Escape from LA" bombed at the box office, the script was reworked, and Snake was rewritten into the character "Desolation" Williams.
Trivia: The film was shot primarily at the Danvers State Asylum, an abandoned hospital. The script was written around the shooting location based on what rooms and corridors were safe to shoot in. Little to no set-dressing had to be done for the film, as it was suitably dilapidated and filled with abandoned medical equipment, which helped add to the film's atmosphere.
