The Exorcist is a movie first released in 1973, based on the 1971 novel by William Peter Blatty, which was based on the case of Robbie Mannheim. The novel and the movie depict a girl possessed by the devil and efforts at exorcism by a priest at the request of the girl's mother. It had several sequels, the first of whom (1977) featured the same player as the possessed girl from the first film.
The movie caused a national sensation in the United States. It broke the record for the biggest grossing movie of all time, and was nominated for ten Academy Awards. But its depiction of possession by the devil was controversial, and it won only two: Best Adapted Screenplay and Best Sound.
In the United Kingdom the film was banned from cinema, television and video release from 1984 to 1998, due to its disturbing themes and content.
It was re-released in 2000 with the original edited scenes reinstated.
