The film's tagline, "Keep telling yourself it's just a game," was used for several years as the advertising slogan for the Ouija board game.
The name can either be pronounced 'wee-ja' or 'wee-gee'. Charles Kennard, founder of the company manufacturing the boards, claimed he learned the name "Ouija" from asking the board what it wanted to be called.
Hasbro Studios' first horror film.
Far from being ancient, the Ouija Board was patented on May 28, 1890.
None of the actors portraying teenagers in the film were actually in their teens. The youngest actor was Olivia Cooke who was 21 at the time of filming.
