Back in November, we brought you the news about Katee Sackhoff (Battlestar Galactica) being in talks to join the cast of director David Twohy‘s forthcoming installment in the Riddick franchise, in the female lead role opposite actor Vin Diesel.

Now, Sackhoff herself has confirmed via Twitter that she has indeed joined the cast, and Variety reports that actor Jordi Molla (Colombiana) is now in talks to join the cast as well.

Synopsis:

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.

Riddick is slated to hit theaters in 2012.
