Eric Roberts will star in The Human Centipede 3 (Final Sequence), Digital Spy said.
The Dark Knight actor will join returning villains Dieter Laser and Laurence R Harvey in the cast of the controversial horror sequel.
Tom Six, writer and director of the franchise, will also appear in the film alongside Tommy Lister, Robert LaSardo and Bree Olson. Six has claimed that the third installment will make its predecessor "look like a Disney movie".
Human Centipede 3 is currently filming in California and will feature a 500-person centipede, according to EW.
Roberts's recent work includes biopic Lovelace, Hansel & Gretel: Warriors of Witchcraft and TV series The Young and the Restless.
He was nominated for a 'Best Supporting Actor' Oscar in 1986 for his role in Andrey Konchalovskiy's Runaway Train.
