A while back Dimension Films removed Halloween 3 from it's 2012 release date, and didn't give much reason as to why. The only thing that was mentioned is that it was the release date was to be determined, and that Dimension was still very serious about getting the film made. Well that has all apparently changed according to franchise director Rob Zombie. According to him, while talking to Scifi Now, there are no plans at all to do the third movie. "I don’t think they are doing anything with Halloween at the moment,” said Zombie. “That is the last thing that I heard." He also seems to still be upset with the way the second installment didn't do overly great. Citing just calling the film Halloween 2 as the reason most people didn't go out and see it.
What about if the film ever does gain some momentum again can we expect Zombie to direct? Nope! He went on to say about the possibility of directing a third movie, "I’m definitely not directing it if they ever do go ahead with a third movie." So it sounds like once he lost interest in directing the movie Dimension lost interest in making the movie all together. Whatever the case may be it seems like it's going to be a while before we see Michael Myers terrorizing babysitters.
