At least, that's if Shawn Adler of MTV Movies is to be believed. Diesel was quoted saying, "David Twowy right now is writing the scripts. The only question is whether we take a page from the Lord of the Rings guys and try to shoot the two chapters at the same time. There are two more in mind," he said of Riddick, the Furyan warrior first introduced in the 2000 film Pitch Black. For a sequel that only brought in $57 million domestically and $115 million total worldwide on a $105 million budget, it seems like a long shot for a studio to take a chance on a double shoot. But who knows? Anyone interested in more Riddick?
