Exclusive Video: Vin Diesel and Katee Sackhoff Talk 'Riddick'

Riddick is the third release in the franchise starring Vin Diesel and directed by David Twohy. The Riddick films - which also consist of Pitch Black and The Chronicles of Riddick - have been a passion project for the pair for over a decade. The official synopsis: "The infamous Riddick has been left for dead on a sun-scorched planet that appears to be lifeless. Soon, however, he finds himself fighting for survival against alien predators more lethal than any human he’s encountered. The only way off is for Riddick to activate an emergency beacon and alert mercenaries who rapidly descend to the planet in search of their bounty. 

"The first ship to arrive carries a new breed of merc, more lethal and violent, while the second is captained by a man whose pursuit of Riddick is more personal. With time running out and a storm on the horizon that no one could survive, his hunters won’t leave the planet without Riddick’s head as their trophy."

We spoke to Riddick stars Vin Diesel about why it took so long to get the sequel going, and Katee Sackhoff about playing a feminine character who could kick all the boys' asses.

Riddick opens in theaters September 6th.
