About Antrum

Antrum is a 2018 Canadian horror film written and directed by David Amito and Michael Laicini. The film is divided into two parts: an opening and closing frame narrative in the form of a mockumentary and a feature film. The documentary purports to tell the story of Antrum, a movie released in 1979 that supposedly has deleterious effects on those who watch it, similar to the cursed film in Ring (1998). The bulk of the movie is allegedly the only known print of the film, which has itself been altered by an unknown third party.
