Human Centipede 3 to involve a 500-person centipede

The first film joined three, the second ten

There wasn't really any other way to progress this franchise than by connecting more mouths to butts was there? Human Centipede Part 3 (Final Sequence) will see 500 victims conjoined into one digestive tract. In a prison.

I imagine you're not really concerned with which actors, producers etc are returning from the previous films, so let's cut straight to the plot synopsis (from EW):

'Bully prison warden Bill Boss (Dieter Laser), leading a big state prison in the US of A, has a lot of problems; his prison statistically has the highest amount of prison riots, medical costs and staff turnover in the country. But foremost he is unable to get the respect he thinks he deserves from his inmates and the state Governor (Eric Roberts). He constantly fails in experimenting with different ideas for the ideal punishment to get the inmates in line, which drives him, together with the sizzling heat, completely insane.

'Under threats of termination by the Governor, his loyal right hand man Dwight (Laurence R Harvey) comes up with a brilliant idea. A revolutionary idea which could change the American prison system for good and save billions of dollars. An idea based on the notorious Human Centipede movies, that will literally and figuratively get the inmates on their knees, creating the ultimate punishment and deterrent for anyone considering a life of crime. Having nothing to lose, Bill and Dwight create a jaw-dropping 500-person prison centipede.'

Key questions:

Does the prison have a cell big enough to fit 500 people joined ass-to-mouth?

Is hot weather a legitimate motive for this kind of insanity?

Is this a social commentary on institutionalisation and recidivism?

Why not a Human Ouroboros?
