Human Centipede franchise stars Dieter Laser and Laurence R. Harvey will both play lead roles in Human Centipede Part 3 (Final Sequence). The controversial horror series’ writer-director Tom Six has also cast himself in a supporting part for the concluding entry in the Human Centipede trilogy.

This casting, which has been exclusively revealed to EW by producer Ilona Six, will be big news for fans of the Human Centipede movies. German actor Laser chillingly played a crazed surgeon who stitches three people together in the first film while U.K. actor Harvey portrayed an equally deranged parking lot attendant called Martin who goes one better (actually, around eight better) in the second entry, which was initially banned in Britain.

The first Human Centipede film became instantly infamous upon its release in 2010 and has been parodied by South Park and Funny or Die, amongst others.

According to Ilona Six, principal photography on Human Centipede 3 will take place this May and June in the southern states of the U.S. The producer also confirmed that the American finale of the series is set for a 2013 release and will be “100 percent politically incorrect.”
