In the scene where Mark is about to kill the 'model' "Milly" she lays on the bed bare breasted. For the US version they had to re-shoot with her breasts covered.
The film proved to be problematic for the BBFC who demanded around 7 mins of cuts. Among these were reductions to the murder scenes, closeups of the spike on Mark's camera, all shots of nude girls in photo albums and on colour slides, closeups of a woman's disfigured face, shots of Milly lying on the bed, and dialogue during the conversation between the police officers in the car. Later video and DVD releases contain much of the footage, suggesting that not all of the cuts were made, although the original uncut print now appears to be lost forever.
The film was a very problematic one for the BBFC who requested heavy cuts for its original cinema release. Among these were reductions to the murder scenes, closeups of the camera spike, shots of a woman's disfigured face, and a shortening of the dialogue between the police officers discussing the murder descriptions. They also requested the removal of all visible shots of nude women in photo albums and slides, and a shot of Milly lying topless on a bed before her eventual murder (this was replaced with an alternate clothed shot). It remains unclear if all of the above cuts were actually made, as later video and DVD releases contain much (though not all) of the footage. The topless shot of Milly was intact on the 1996 UK Warner video and also appears in DVD releases.
