The director wrote the screenplay
based on a comment he once made at a party about how all rapists etc should have their arse stitched to a fat trucker's arse as punishment. This basic premise then gave way to the idea for the film.

The sequel is based on the premise that the protagonist has seen the first film and is sexually aroused by it, so he kidnaps a bunch of people and carries out the same experiment on them for his own sexual gratification. It includes a scene where he rapes the back end of the centipede, with his cock wrapped in barbed wire, hence why so many censors won't pass it.
