David Twohy is hard at work finalizing visual effects and sound mixing for the
Riddick sequel. Twohy takes some time to release a look at the official logo as well as the first image of
Karl Urban as Vaako to further tease your interest.
He says on his official blog:
Been pulling 14-hour days trying to finish RIDDICK. My typical day starts at 9am with intensive visual effects meetings, sweating out the details of our 900 VFX shots. Then I jet across town to the mix stage, Soundelux, where I supervise the sound, balancing out the often-competing elements of music, sound fx, sound design, and dialog. At night I hit the lab, Technicolor in Hollywood, staying until midnight to do ‘DI work' — color-correction of the movie. This is where David Eggby and I have one last chance to get the images right, dropping in grads and power windows to finesse what we shot on set. It's a great tool, the Digital Intermediate. Kind of like Photoshop for movies. Gotta love it. Gotta love the challenge of bringing it all home.

As for Urban's Vaako, it looks like he has been still blue-screened onto the backgrounds as well as in Chronicles of Riddick while fights for survival against alien predators. Vaako of course becomes more powerful and dangerous than ever and returns to his home planet of Furya to save it from destruction.
Riddick, which does not have a release date yet, also stars
Vin Diesel, Karl Urban, Jordi Molla, Matt Nable, Katee Sackhoff, Bokeem Woodbine, Dave Bautista, Conrad Pla, Raoul Trujillo, Nolan Funk and
Keri Hilson.
The latest chapter of the saga that began with 2000's hit sci-fi film Pitch Black and 2004's The Chronicles of Riddick reunites writer/director David Twohy and star Vin Diesel (the Fast and Furious franchise). Diesel reprises his role as the antihero Riddick, a dangerous, escaped convict wanted by every bounty hunter in the known galaxy.
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.
