Vin Diesel Posts New Riddick Concept Art

Vin Diesel took to his Facebook page to share a new piece of concept for the third Riddick film that he and David Twohy are currently working on. The update posted by them last month revealed that they are working on getting financing for the new film, and are still planning on filming an R-rated version:

Vin Diesel: "We can start filming this summer. However, there is a catch… in order for us to make a true R rated film, I must work for scale upfront. Not unlike the “Find me Guilty” experience (which I wouldn’t have changed for the world)…

Money is always second to art, integrity and spirit… but the real issue is deeper. Can I suspend my life, to momentarily venture to that dark place… called Riddick."
