Bloody Disgusting learned that filming is now underway on Rob Zombie’s fan-backed 31, his Halloween slasher that’s heading to Murder World.

Joining the previously announced cast is Zombie regular, Malcolm McDowell, who plays Dr. Loomis in Zombie’s Halloween films.

McDowell plays ‘Father Murder’, the owner of Murder World for which the film is based.

Judy Geeson plays ‘Sister Dragon’, who runs Murder World alongside McDowell. She joins David Ury, who will be playing Schizo-Head, one half of murderous team of brothers living inside Murder World. Lawrence Hilton-Jacobs was recently cast as Panda Thomas, with Elizabeth Daily (E.G. Daily) playing ‘Sex-head’, and Torsten Voges as the insane partner of Death-Head.

Daniel Roebuck plays Paster Victor, an unfortunate participant in last year’s game of 31.
