Having slurped down all the goodwill of The Dark Knight only to pass it through The Expendables, Eric Roberts will now reportedly shit the rest out on the final chapter of The Human Centipede series. EntertainmentWeekly brings word the actor has attached himself to The Human Centipede III: Final Sequence, joining an increasingly-grotesque chain that includes former series participants Dieter Laser, Laurence R. Harvey, and mastermind Tom Six, along with newcomers "Tiny" Lister and porn star Bree Olson. The story doesn't say what role Roberts will play, but the IMDb is already crediting him as "Governor", hinting that he will play at least a head of state if not digestive tract. It also credits the actor as being in roughly 70 other roles this year, seriously, so don't worry Eric Roberts fans: if your stomach turns at the idea of watching Julia Roberts' brother sewn onto someone's butt, there will still be plenty of other opportunities to watch him in marginally less wretched films. Hansel & Gretel: Warriors of Witchcraft, Doctor Me, and the apparently non-satirical A Talking Cat!?! all look like strong options.
