Trivia: In the scene where Anna is outside the gates during "For The First Time in Forever", you can see the backs of Flynn and Rapunzel from "Tangled".
Trivia: The real Marcus Luttrell appears several times throughout the movie: he spills the coffee and tells the new guy to clean it up; he's in the operation briefing and shakes his head at the rules of engagement being read; and he's on board the Chinook helicopter when it is shot down.
Trivia: In the end credits the minion causing the screen to drop has heterochromia iridum - his eyes are two different colors. (01:30:45)
Trivia: This is Rachel McAdams' third time travel film (she also stars in The Time Traveler's Wife and Midnight in Paris), but her character hasn't time traveled in any of the films, it's always someone else.
Trivia: Once again, Stan Lee makes his usual cameo. This time, he appears as a judge at the Christmas pageant. (01:03:50)
Trivia: During the outtake scenes, they turn on the radio and Jason, Will, and Emma start singing along to "I'll Be There for You" (instead of "Waterfalls"). This was the theme song to the show "Friends" starring Jennifer Aniston.
Trivia: The person who introduces Leonardo DiCaprio onstage at the end of the film is the real Jordan Belfort.
Trivia: In the beginning of the scene in the Master of Laketown's house, Alfrid tries to empty a chamberpot through the open window. During this, the window half closes, so much of the contents of the chamberpot splash on the inside of the window and windowsill. In the extras of the Extended edition it is told that this happened during the first take, and the scene was reshot many times. Nevertheless, the first take ended up in the final cut. (01:11:35)
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: 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: Tom Hanks is the first actor to play Walt Disney in a mainstream feature film.
Trivia: When The Joker interrupts the ceremony and shows the video of him blowing up the building, there's a scene where he hits the detonator a few times before the building blows up. This is a scene paying homage to what happened in The Dark Knight when there was an actual unplanned delay during filming of the explosion going off during the blowing up of the hospital.
Trivia: As Kirk, Spock, and Uhura head to the shuttle bay for their mission to Kronos to capture Khan, Sulu orders crew to prepare the vessel that was confiscated in the Mudd incident. This is a reference to Harry Mudd, a roguish character who appeared in the original Star Trek series in the episodes titled,"I, Mudd" and "Mudd's Women." Harry Mudd, played by Roger C. Carmel, was the only non-regular character to appear in more than one episode on the original Star Trek series. Carmel was slated to reprise the role in Star Trek: TNG, but he died before the episode could be filmed. (00:44:25)
Trivia: In addition to many other nods to the original film, this remake also has several audio clips taken directly from the original film. One of the more noticeable instances of this is when Mia is first possessed, right after the door is thrown open by the force outside of the cabin (right before she vomits blood onto Olivia and is thrown into the basement). The lines "You will die, like the others before you! One by one we will take you!" can be heard in the background as Mia screams. This is taken directly from the original film, from the scene where Cheryl was possessed. In addition, when the main characters first arrive at the cabin, a low, demonic voice moaning "Join us" can be heard in the background. This is another audio clip taken from the original film.
Trivia: Early in production, the film was under the working title "Die Hard 24/7", leading many media outlets and fans to speculate that the film was to be a crossover with another popular Fox property- the television series "24." (An unnamed studio insider even told a popular movie-reporting site that Fox had been tinkering with the idea very early in production to try and shake-up and revitalize both franchises.) The title and concept of the film were subsequently changed.
Trivia: Stan Lee makes his usual cameo, this time as a patient at the asylum where Selvig is being held.
