Katee Sackhoff has been offered the role of Dahl, a mercenary tracking Vin Diesel's title character, and Andreas Apergis was offered Krone, the commander of an evil theocracy. It isn't known what roles Bokeem Woodbine and Dave Bautista are up for. We reported last month that Karl Urban is returning as Vaako, a role he played in The Chronicles of Riddick.
David Twohy is directing Riddick from his own screenplay. Last month, Vin Diesel revealed shooting was slated to begin shortly, although this new report indicates production has been shut down for now.
