Last month at Comic-Con, Peter Jackson was understandably reluctant to discuss the future of his gritty sci-fi summer movie, "District 9." He'd only just screened the film in front of an audience for the first time.

"We're superstitious," Jackson, who produced the film, told MTV News at the time. "Sitting down and talking about sequels when you haven't even released the movie is, I think, tempting fate. We'll get the film released, see how it does."

After notching the top spot at the box office over the weekend, raking in $37 million since its Friday opening, Jackson, director Neill Blomkamp and star Sharlto Copley might now have to sit down and have a serious talk about the possibility of turning "District 9" into an enduring sci-fi franchise.

In fact, Copley said that the very nature of the production — its improvisatory dialogue, the filmmakers' decision to shoot tons of material and see what developed — left nearly enough video on the cutting room floor for another installment. "The behind-the-scenes DVD is gonna be crazy because we shot an enormous amount of footage," the actor said. "There were a lot of exciting avenues to want to go down and you really [have to fit it all] into a small block of time."

No spoilers here, but suffice to say that the movie, which tells the alternate-reality story of an alien ship trapped for decades in South Africa, creates a rich historical backstory, only some of which is revealed by the end. The fully realized "District 9" mythology could easily spawn a sequel, a prequel, a video game, an animated movie or something else entirely.

While it was too soon at the Con for Blomkamp to voice his preference for the future of "District 9" as a franchise, he expressed his desire to revisit the material at some point. "When I started thinking about it, I thought I'd totally like to go back to the creative universe of 'District 9' for sure," he said. "Hopefully there's a place for that sometime in the future. It has to kind of do well first."

Well, it kind of did really, really well. And then, of course, there's the small matter of deciding which idea to move forward with and in what medium.

"I believe movies should come from the heart, and if there's any sequel or continuation of 'District 9,' it should only be because there's a good idea involved, not because it's a money-making venture," Jackson said.
