Among the statements made:
David Twohy: "The movie itself is going to be a lot like Pitch Black because of the money involved... because we want to maintain our R-rating..."
Vin Diesel: "Which is a big deal."
David Twohy: "At any cost. It costs us a lot. [...] So it'll be probably a little tougher than, say, Chronicles [of Riddick] in that regard... We are going to be lean and we're going to do it quick, and it's going to be a cool movie, I can tell you that."
