Production continues in Montreal on the sci-fi sequel Riddick, where Vin Diesel returns as Richard Riddick, the character he made famous in Pitch Black and The Chronicles of Riddick. The actor took to his Facebook page once again to share two photos from the set, where he is featured alongside director David Twohy. Take a look at these shots along with Vin Diesel's own captions.

"On set Riddick production still... Proud of my director... when you see this film, you'll know why... GRRR!!"
