As mentioned earlier this week, The Human Centipede 3 has started filming in Los Angeles and we now have new plot details. *Note: some of the information may be considered as spoilers, so don't continue reading if you don't want to know anything about the movie.

The plot details below come from a recent casting call notice, and suggest that the majority of the movie will be taking place in a prison. Dieter Laser and Laurence R. Harvey are back for the third film as new characters and are said to be playing "a villainous duo with a storyline no one will expect.” Other previously released details include the mention that “a big American celebrity” will appear in the film and that Tom Six is still moving forward with plans to put together a 500-person human centipede.

"HUMAN CENTIPEDE 3, a horror film, is looking for gentlemen of all ages, sizes, and ethnicities to play PRISON INMATES starting THURSDAY - MAY 16 in LOS ANGELES. These prisoners will work up to 13 DAYS between MAY 16 and JUNE 6. We will be shooting at a number of actual PRISONS in the LA area. Applicants can be expected to engage in regular prisoner activities like RIOTING, SCREAMING, and FIGHTING. However, this is a HUMAN CENTIPEDE movie. THERE WILL BE SOME SCENES TOWARDS THE END OF THE SHOOT REQUIRING PRISONERS TO BE PART OF THE HUMAN CENTIPEDE. Actors will be fully clothed, but will be asked to pose on their hands and knees rear end to mouth. Please do not apply if uncomfortable with this process."
