In an interview with MTV, Vin Diesel said that writer-director David Twohy is currently working on the scripts, and that the “only question” is whether they will be shot together, LoTR-style, or as two separate productions. Why did it take so long? No money problems, Diesel insists — they just want to get it right. This was, after all, envisioned as a trilogy, with Pitch Black acting as a stand-alone companion film.

I think they should have stopped at Pitch Black, I really think they had lightening in a bottle with that movie and with all these sequels they are just diluting the awesomeness that was Riddick’s character in Pitch Black.
