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: 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: The spears shown in the lab are from Predator 2 and Alien vs Predator.
Trivia: In the end scene (right before the lead characters go into the cafe shop) you can see a bus drive past with the number 180 printed across the top. The number 180 was a significant number in the first three Final Destination films.
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: Actual "Cannabis Experts" were brought in to consult with actor Fran Kranz, so he could properly portray a convincing stoner in the film.
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: During the opening of the film, Lindsay Seim portrays the younger Elise in the flashback sequence. However, Lin Shaye, who plays the older Elise, dubbed over Seim's dialog in post production. Director James Wan stated that this was done because Shaye has such a unique voice, and thus, it allowed her presence to be felt early in the film.
Trivia: For the scene in which Jonathan drives a stake into Lucy's heart, Steven Weber's reactions to getting doused in blood are real. For this particular sequence, Mel Brooks did not tell him what was going to happen.
Trivia: Jimmy didn't die even though it never shows him after he faints on the steering wheel in the car with Lori. He simply passed out. The television cut shows him alive in the ambulance at the end, but for some reason in the theatrical version, they left it out for us to 'wonder'.
Trivia: In the scene where the judge is killed by the two sentries, one of the sentries is played by director Sam Raimi (of Spider-man fame).
Trivia: When Billy's mom takes the picture of Gizmo at the beginning, Gizmo becomes frightened and runs over to Mr. Peltzer. When the scene is slowed, you can see the puppeteer's hand underneath while operating the Gizmo doll. Not a mistake as needs slo-mo, but worth a look. (00:19:10)
Trivia: At the very end of the movie when the new kids are telling the story, they make a sarcastic comment about the killer being the girl from the Noxzema commercials. The girl who played the killer, Rebecca Gayheart, really was the girl from the Noxzema commercials.
Trivia: Like Tanedra Howard won a role in Saw 6, Gabby West won the second season of Scream Queens and is featured in this film. She is Kara, Evan's girlfriend. She is underneath one of the rear wheels of the car in the garage trap.
Trivia: When Van Helsing is fighting Dracula towards the end as a werewolf, he stops to get out his claws. This is an obvious reference to Wolverine, whom Hugh Jackman played in both "X-Men" movies.
Trivia: Mr. Tuttle is also the name of the housekeeper from another haunted-house movie, "The Changeling" (1960).
Trivia: In the hospital Heather is told that she can not be in a certain area without a pass; she replies "Screw your pass." The very same line was spoken, by her character Nancy in Nightmare on Elm Street 1, to a hall monitor in her dream.
Trivia: Kirsten Dunst (Claudia) had her first on screen kiss, with a much older Brad Pitt, in this film.
