Hellraiser (also known as Clive Barker's Hellraiser) is a 1987 British horror film written and directed by Clive Barker, based on his own novella The Hellbound Heart. The film spawned a series of sequels.
Clive Barker had to make some cuts on the film after MPAA gave it an X rating. Following scenes were cut for R rating; Two and a half shots were excised from the first hammer murder, including a closeup of the hammer lodged in the victim's head. In the scene where Julia murders another man, the actor playing the victim felt that it made sense for him to do so naked. The nude murder scene was shot but, ultimately, replaced with a semi-clothed version. Close-ups of Kirsty sticking her hand into Frank's belly, exposing his guts. Longer version of the scene where Frank is being torn into pieces by the Cenobites' hooks. Final shot where his head explodes and his brain messily splashes out was also cut. (Wikipedia)
