Be the first to tell all the kids at Riddick Club the next Pitch Black sequel WILL have trisons (three-legged bisons, naturally):
Though billed as a back-to-basics approach to the character popularized by Diesel, the script features the character -- the most wanted man in the galaxy -- left for dead on a barren alien planet, dealing with "trisons" (three-legged bisons) and "mud demons." He must then contend with two squads of bounty hunters, one of which ride rockets called jetcycles.
Mud demons, bounty hunters, jetcycles, AND trisons. You're getting all that on one bill. This film is an overflowing Christmas stocking, for you. For us.
