When we last saw Riddick (Vin Diesel) he had just killed the Lord Marshal and was leading The Necromongers (The Chronicles of Riddick). It seems that things didn’t go as planned and Riddick is once again on the run and battling aliens that want him dead and evading capture from mercenaries who seek to claim the bounty on his head. Just another day at the office for Riddick . I am curious to see what happened with the Necromongers and how it ties into the new film. Karl Urban in listed in the casting so I am sure we’ll be seeing Vaako.
