The British Board of Film Classification announced today it is refusing to give a DVD certificate to horror sequel Human Centipede II (Full Sequence). In its ruling, the BBFC also detailed the plot of the film, which up until now has been shrouded in secrecy.

Human Centipede II (Full Sequence) is the sequel to last year’s Human Centipede, in which a mad doctor stitches together three victims to make the monstrous creation of the title. Since its release, the deranged nature of the first film has become fodder for many comedians. Just last night, MTV Movie Awards host Jason Sudeikis joked that the Human Centipede should have been nominated for “Best Kiss.”

In its ruling, the BBFC declared:

There is little attempt to portray any of the victims in the film as anything other than objects to be brutalised, degraded and mutilated for the amusement and arousal of the central character, as well as for the pleasure of the audience. There is a strong focus throughout on the link between sexual arousal and sexual violence and a clear association between pain, perversity and sexual pleasure. It is the Board’s conclusion that the explicit presentation of the central character’s obsessive sexually violent fantasies is in breach of its Classification Guidelines and poses a real, as opposed to a fanciful, risk that harm is likely to be caused to potential viewers.

In the course of the ruling, the BBFC described the premise of the film, which we won’t reveal here as it is both a spoiler and extremely NSFW.

The British distributor of the DVD has six weeks to appeal the decision. The BBFC noted that, for reasons which are currently unclear, Human Centipede II (Full Sequence) has not been submitted for a cinema release in the U.K. Director Tom Six recently told EW that the film would be released here “after the summer.” The film’s U.S. distributors, IFC, declined to comment on the BBFC’s ruling.
