The British Cinema version was cut by around 1 minute to remove the drill sequence. This version was released on video in the UK before 1984, after which all videos were required to be submitted to the British Board of Film Classification. When it was finally given a video certificate by the BBFC, further cuts were made to remove the intestinal vomit scene, and the brain squashing scenes. The UK video has a total of 2m 21s of cuts.
