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: 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: Tom Hanks is the first actor to play Walt Disney in a mainstream feature film.
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.
Trivia: Warm Bodies actually has tons of references to Shakespeare’s Romeo and Juliet, it is kind of a modern adaptation. The zombie, R(omeo), falls in love with the human girl Julie(t). An impossible love, as both “species” fight against each other. Julie has an Italian last name, Grigio, has a boyfriend, Perry, who represents Paris from Romeo and Juliet. But there is another similarity that makes it much more obvious: Ever thought about the scene at Julie’s home, where she is standing on her balcony and looking down to R? And suddenly, Nora (who obviously represents the nurse) shows up? We know that scene very well. And finally, their love unites zombies and humans and stops their war. Fortunately, the ending is not inspired by the play .
Trivia: The waiter who brings Nick to Jordan's table to meet for tea after his lunch with Gatsby is the film's director, Baz Luhrmann.
