Vin Diesel is back as the formidable interplanetary fugitive first seen in Pitch Black (2000) and The Chronicles of Riddick (2004). This time, he's been left for dead on a sun-blazed world inhabited by predatory monsters; he finds his way to a deserted outpost and broadcasts his presence into space, planning to steal a ship and escape when bounty hunters show up to capture him. Writer-director David Twohy plops us down in the middle of his story and leaves us hanging at the end, waiting for Episode 4. In between, the movie is a harsh, gritty pleasure, straightforward and tautly suspenseful, and showcasing Twohy's knack for portraying truly alien worlds. Jordi Mollà, Matt Nable and Katee Sackhoff play three of the bounty hunters, and there's a cameo by Karl Urban as Riddick's nemesis from Chronicles.
