A third Riddick film is in development titled, simply, Riddick. As of August 10, 2011 they have begun casting.[15][16]
Riddick is being financed independently, meaning there won't be as much over-the-top effects and action as with Chronicles, but more a rough simple feel like with Pitch Black.[15][16]
The plot will find the titular criminal once more on the run from mercenaries who want the hefty reward his head will bring, he once again ends up on a planet teaming with unfriendly alien beasts. The beginning of the story will likely tie into the ending of Chronicles and feature cameos from characters who have appeared in the previous films.[15][16]
