Trivia: When Casey enters the shop, the female store clerk is watching the TV. On top of the TV is a piece of memorabilia from The Iron Giant. The director of Tomorrowland, Brad Bird, also directed The Iron Giant.
Trivia: New Line Cinema had tried to re-work this film into a sequel to David Fincher's "Se7en" for some time, but nobody involved in the making of that film wanted to work on a sequel - especially one with a supernatural element. It was eventually made under its original title and without any connection to the Fincher film.
