Trivia: Actual "Cannabis Experts" were brought in to consult with actor Fran Kranz, so he could properly portray a convincing stoner in the film.
Trivia: The moths that fly out of Billy's mouth after he cuts the thread are real, the actor held them in there for the effect.
Trivia: A scene in which Sebastian brutally and graphically rapes his neighbor was filmed, but was mostly deleted as test-audiences felt it made Sebastian far too evil. And thus, the version of the scene in the theatrical cut only alludes to the idea without directly showing it. The original scene was reinstated in the director's cut released on DVD and Blu-Ray however.
Trivia: Peter Capaldi, the new Doctor Who for 2014, is listed in the credits as W.H.O. Doctor. Just a fun coincidence, as the roles are too far apart to have been planned, but worth a look.
Trivia: Director Russell Mulcahy manages to insert his name in this movie: Lamont Cranston's butler is addressed as "Russell" by Margo Lane at Cranston's residence, and there is a delivery truck with the name "Mulcahy" emblazoned on the side of the vehicle.
Trivia: The scene with Jill eating Wesker's sandwich and saying "It's Jill's sandwich now!" (although saying it quickly in such a way that you can't hear the "s" and it sounds more like "It's Jill sandwich now!") is a reference to an infamous moment in the original video game. In the game, Jill is almost crushed by a booby-trap, and the character Barry says she was "almost a Jill sandwich!" The poor dialogue and terrible delivery by the voice actor ended up making the moment a meme many years later.
Trivia: When the kids are walking down the stairs in the subway station, you can see one guy walking upstairs dressed as the character Mojo Jojo from "The Powerpuff Girls." Mojo Jojo was voiced by Roger L. Jackson, the same voice actor for Ghostface.
Trivia: The three victims of Michael found in the playground are wearing masks that look exactly like the ones from Halloween III: Season of the Witch.
Trivia: To help promote the movie "Jason Takes Manhattan", Kane Hodder appeared on The Arsenio Hall Show as Jason. He remained in character the whole time and never spoke.
Trivia: The directorial debut of series co-star Patrick Wilson.
Trivia: Makeup artist Rick Baker has a cameo appearance in this film. He's the man who whistles to his comrades who are approaching the gypsy camp then a few seconds later, gets killed by the werewolf.
Trivia: Reportedly, star Kevin Bacon was at a rough patch in his life during production and didn't understand the appeal of the film or the light-hearted comedic elements. (Even once breaking down in public and exclaiming in frustration "I'm in a movie about giant underground worms!") And thus, he chose to have no involvement in the sequels. It wasn't until some years later that he decided to re-visit the film and give it another chance after it became a massive cult-hit, and discovered that he actually really loved it. Bacon has since gone on record saying one of his dream projects would be to reprise his role of Val McKee in a future film.
Trivia: When Lorraine Warren is dreaming about the demonic nun in her house, the demon actually reveals its name in 2 ways. The first is the way Lorraine realises at the end of the movie (written in the Bible). However, the audience is another way-the gold letters on the bookshelf behind her also spell out the name "Valak."
Trivia: Director Gerald Thomas provided the monster gibberish for Oddbod Jr.
Trivia: The spears shown in the lab are from Predator 2 and Alien vs Predator.
Trivia: At one point early in production, the film was going to be slightly retooled in order to make it the third entry in the "Cloverfield" franchise, following "Cloverfield" and "10 Cloverfield Lane." Eventually, this idea was dropped, and the movie was left as a stand-alone film.
Trivia: During Joey's nightmare, he is seduced by a topless nurse who then captures him before turning into Freddy. As originally conceived, only her face was going to transform at first, thus having Freddy's burnt male head on top of an otherwise perfect topless female body in order to create an eerie, otherworldly look. The actress portraying the nurse even took part in some test shots and performed the scene under heavy prosthetics to make her face look exactly like Freddy's. However, the effect was cut as the crew felt it looked far too weird, and that it diminished the moment when Freddy fully appears on-camera in the scene.
Trivia: The profuse drooling that Wallace suffers once he has been "transformed" into the walrus could not be helped - actor Justin Long was constantly drooling due to the heavy prosthetic makeup, and the fact he had to hold his tongue back to simulate the fact that his character's tongue had been cut out.
Trivia: A lot of the witches who attend the Grand High Witches meeting are actually men dressed in women's clothing.
