The unrated director's cut of The Chronicles of Riddick adds about 15 minutes of action, sex, and even exposition. There's a new introduction for Kyra, three scenes of a character (Shira, played by Kristin Lehman) who was removed entirely from the theatrical cut, more interplay between Riddick and the Lord Marshal and between Vaako and Lady Vaako, and a more striking ending.

Vin Diesel reprises his star-making "Pitch Black" role of enigmatic anti- hero Richard B. Riddick in the new science fiction action-adventure epic, "The Chronicles of Riddick". Riddick has spent the last five years on the move among the forgotten worlds on the outskirts of the galaxy, eluding mercenaries bent on collecting the price on his head. Now, the fugitive finds himself on planet Helion, home to a progressive multicultural society, which has been invaded by the Lord Marshal (Feore), a zealot who targets humans for subjugation with his army of warriors known as Necromongers. Exiled to a subterranean prison where extremes of temperature range from arctic nights to volcanic days, Riddick encounters Kyra (Davalos), the lone survivor from an earlier chapter in his life. His efforts to free himself and Kyra lead him to the Necromonger command ship, where he is pitted against the Lord Marshal in an apocalyptic battle with possibly the fate of all beings-both living and dead-hanging in the balance.
