Trivia: The Beyond
- Author Existence Failure: David Warbeck had written a screenplay for a sequel to the film but his death put an end to it ever seeing the light of day. Blackest Heart Media DID buy the rights to make a comic adaptation of the script, but went out of business before production of it began.
- Executive Meddling: The film was supposed to be a straight-up surrealistic gore film about a haunted hotel where people die horribly. Fulci's distributors demanded a zombie shoot-out, hence the side trip to the hospital in the third act and the twist that the hotel's vast basement is connected to EVERY major building in town.
- Keep Circulating the Tapes: The film was extremely popular on the Euro-Horror tape trading scene, thanks to fans who ripped the uncut version off of an uber-rare laser disc version of it.
- No Export for You: The uncut version was widely unavailable in the US for a long time.
