Vin Diesel has revealed concept artwork for director David Twohy's Riddick via his Facebook page. Check out the image below and what the actor had to say:

Concept art and Key frames allow a production to explore possibilities before actually committing to film. The road to the "R" rating, that so many of you were vocal about, has been a long one. The advantage however, (never empower the negatives) was that we were allowed a really extensive preproduction. The art work is so good, the artists have really outdone themselves in illustrating this world at it's early stage.

When this film comes to the screen... know that you willed it into being!

Haha...

P.s. Share your thoughts... It's Sunday and we are, at the very least, allowed to be creative in thought.
