"[The studio] said, 'Let's do some other ones. What other story ideas do you have?'" says the filmmaker. "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."

According to IGN, Rodriguez says he has "an idea" of what he will do with the sequel. The next step, he says, is probably to have 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. As for whether or not he would direct the sequel...

"I don't know," he laughs. "I think I have too many people wanting me to do Sin City 2 first!"
