Director David Twohy has revealed on his official site that he's still keen on further work with his beloved Riddick (Vin Diesel) character.

Twohy says that "All I can say now is "We're talking about it." The DVD numbers were really good - we know that, and some potential financiers know that. But if another movie surfaces, it probably won't be a Universal movie and probably will be an independent movie. Which means we'll have to make it for substantially less than the last installment."

He's ready for the challenge though - "That's okay. 'Pitch Black' was $22 million all in. Maybe it's time to go back to our roots - as we go on to The UnderVerse."
