‘Riddick’, the next installment in the ‘Pitch Black’ series, is now official. Universal gave writer/director David Twohy (Imposter) the go-ahead for the film, which was rumoured to focus more on Riddick than on the universe in which he lives. However, reports say that the movie features Vin Diesel’s character as the most wanted man in the galaxy. He is left to die on an alien planet inhabited by such things as trisons (three-legged bisons) and mud demons. He’s also being chased down by two gangs of bounty hunters, and one of those gangs ride rockets.
