Could The Human Centipede be assembled in a prison for the Final Sequence?

Earlier this week we shared the news that Tom Six's THE HUMAN CENTIPEDE 3 (FINAL SEQUENCE) was set to begin filming today in Los Angeles. While the storyline has been kept under wraps we do know that Six has stated that the film would contain "a megalomaniac 500 + human centipede", which already sounds repulsively awesome. And just how would a 500 + human centipede be made up? Some recent rumblings suggest the participants in this final sequence may be inmates at a prison.

While we haven't heard confirmation on the setting of THE HUMAN CENTIPEDE 3 being a prison, in doing some scouring around the internet we came across a casting call for the film that reads:

HUMAN CENTIPEDE 3
Theatrical, Non-Union Posted: 4/24/2013
Category Feature Film
Union Status Non-Union
Rate 64.00/8

PRISON INMATES (NON UNION) / Non-Union / "HUMAN CENTIPEDE 3" / Background / Male / All Ethnicities / 18-65
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. Show is NON UNION. Rate is 64.00/8 + Mileage on some far away prison shoot days.
Rate: 64.00/8

If the casting call above and the rumors that we're hearing hold true then that could easily explain how a 500 person HUMAN CENTIPEDE could come together.

In terms of cast, writer/director Tom Six will be starring, as well as the returning Dieter Laser (FIRST SEQUENCE) and Laurence R. Harvey (FULL SEQUENCE).

We'll keep you posted on news regarding THE HUMAN CENTIPEDE 3 as it crawls our way.
