Vin Diesel continues to releases new images from the set of the currently in production sequel. Now we have our first looks at the characters of Katee Sackhoff, and wrestler turned actor Dave Batista, aka the “new breed” of Mercs that will be hunting down Riddick. Also included is a teaser shot of a “Mud Demon,” vicious dog-like creatures that both Riddick and the Mercs will find themselves up against. The latest chapter of the groundbreaking saga that began with 2000′s hit sci-fi film ‘Pitch Black’ and 2004′s ‘The Chronicles of Riddick’ reunites writer/director David Twohy (‘A Perfect Getaway,’ ‘The Fugitive’) and star Vin Diesel. Diesel reprises his role as the antihero Riddick, a dangerous, escaped convict wanted by every bounty hunter in the known galaxy.
