Speaking to MTV, District 9 director Neill Blomkamp discussed his role in the ill-fated Halo film before it was unceremoniously canned. According to Blomkamp, he poured five months into the movie. He says he worked on the film "24 hours a day," adding that he feels that the "the whole [Halo] universe is incredibly compelling." Still, he reiterates his belief that he probably wouldn't return to Halo, saying, "When you spend five months working on something like that, and then you just get the rug pulled out from underneath you, it's not easy to kind of go back to that."
While he says that he loves the creative part of the process, and adds that District 9 "got born" out of the ordeal, it would be "difficult" to return to Halo. "I wish I could," says Blomkamp, "but I'm not sure that I would be able to."
