With pre-production well underway, David Twohy's Riddick is now starting to put together its supporting cast.  We previously reported that Karl Urban would be returning to the franchise to star alongside Vin Diesel, and now Bloody-Disgusting has some new casting details to report.  According to BD, offers are out to voice Andreas Apergis (Durham County) Katee Sackhoff (Battlestar Galactica) Bokeem Woodbine (The Rock) and WWE wrestler Dave Bautista (The Scorpion King 3: Battle for Redemption).  If Apergis signs on, he'll play play "Krone", commander of the dark theocracy, while Sackhoff would pay "Dahl", a Nordic merc tracking Riddick.  I'm definitely up on the idea of Sackhoff playing a merc, and hopefully Woodbine will top his shocked-death face from The Rock.

Check out the official synopsis for Riddick after the jump.

Here's the official synopsis for Riddick:

Betrayed by his own kind and left for dead on a desolate planet, Riddick (Diesel) fights for survival against alien predators and becomes more powerful and dangerous than ever before. Soon bounty hunters from throughout the galaxy descend on Riddick only to find themselves pawns in his greater scheme for revenge. With his enemies right where he wants them, Riddick unleashes a vicious attack of vengeance before returning to his home planet of Furya to save it from destruction.
