Vin Diesel has been hard at work on the set of Riddick these days, but he still finds time to drop some new photos on his Facebook page every now and then. Today the actor shared another photo from the set, which seems to reveal his title character has a different set of goggles (CLICK HERE to view the last set photo, where he's wearing all black goggles). Maybe these are his surveilance goggles? Who knows. At any rate, click on this new photo of Vin Diesel's title character below to access our growing gallery from the set of Riddick.
