In doing a quick scan of past stories, it seems almost all of the Riddick photos that Vin Diesel has been regularly sharing on his Facebook page are posted on Friday's. What does this mean? Nothing, probably, but perhaps he feels the need to get the weekend started right for his fans. At any rate, today we have our latest shot from director David Twohy's sci-fi action sequel, where the Alpha Furyan is taking out yet another mercenary. This shot also seems to indicate that Riddick has watched his share of Steven Seagal movies, as evidenced by his unique arm-breaking technique.
