David Twohy and Vin Diesel are confirmed to be reteaming for a third Riddick picture. Unsurprisingly, this one is said to be leaner and meaner than the second installment, the astonishingly baggy Chronicles. This is how Variety put it:
…insiders say the third outing will hew closer in tone to the cult hit Pitch Black and will focus on the character of Riddick as opposed to the universe he inhabits.
Somehow I don’t think it will actually end up a “character study” though. We know nothing of the plot so far, though Vin Diesel has been talking about potential sequels for some years. In 2006 he claimed a third film would be set in the “Underverse” and the fourth would be set on Furya, Riddick’s homeworld; last August he said that Twohy was writing two scripts but not what they were.
The film’s scheduling depends somewhat on how shooting for Fast Five, the next Fast and the Furious sequel, is slotted into the calendar.
