Actor Vin Diesel took to his Facebook page yesterday to share a concept art photo from Riddick. He also provided some updates on the production, such as the sequel will be shot in Canada and it will be shot for an R rating. Take a look at the concept art photo below, and read what Vin Diesel had to say about Riddick.

<strong><em>Riddick</em></strong> Artwork
"I hear you...

While I was working on character, the Director and his team of artists have been creating the world and style of this picture. We all know how much I enjoy concept art and storyboards, haha, I am like a kid in a candy shop.

Seeing the early stage of CGI is always fascinating to me, it is a element that usually comes together long after the filming process, so you look forward to seeing it fully realized.

First stop for the Riddick production is Canada, which is where we shot a large part of Chronicles...

P.S. I am grateful to have Universal in such support of this complex character's journey... not many studios would back an "R" rating. Very cool."
