"The studio said, 'Let's do some other ones. What other story ideas do you have?'" the filmmaker told IGN Movies in an interview conducted earlier today. "Because it was like, let's test out the market with this one. They really wanted it to be pretty contained, pretty scaled-back. They didn't want to put too many of the ideas into it that we could save for a second one."
"So we could see what the appetite was, because the bigger movie would actually be what comes following that. That kind of sets up a new storyline, new location and world, and then you can really go crazy from there."
Rodriguez went on to say that he already has "an idea" of what exactly he'd like to do with a follow up to the movie that was released only a few weeks ago. However, the site adds that he now plans on having, "other writers come in and pitch different versions of his basic premise, along with new concepts. And then, as with the first Predators, he'll pick the best one."
And as for whether he'll direct the sequel: "I don't know! I think I have too many people wanting me to do Sin City 2 first!"
