The British Board of Film Classification has refused to certify the sequel for public distribution, citing some truly horrific pornographic scenes from the film.

For those who are lucky enough not to have stumbled across the horror gross-out on Netflix, the film tells the sick tale of a mad doctor attaching three people together in an extremely disgusting way. The Post’s Michael O’Sullivan gave the film one star but said, “If you come with the right frame of mind, and a taste for schlock, there’s a demented kind of fun to be had.”

According to the BBFC, it’s the second film’s new direction, making the idea of the centipede the object of a person’s “depraved sexual fantasy,” that makes it unacceptable for public viewing.

The film’s director has responded to the ruling.

“Thank you BBFC for putting spoilers of my movie on your Web site and thank you for banning my film in this exceptional way,” director Tom Six said in a statement. “Apparently I made an horrific horror-film, but shouldn’t a good horror film be horrific? My dear people it is a [expletive] movie.”

Other films banned by the BBFC include 1932’s “Freaks” and the 2009 Japanese horror film “Grotesque.” Do you think that the BBFC has gone too far in banning the film? Let us know in the comments.
