The official Comic-Con 2013 line-up won’t be unveiled for another few weeks, but Vin Diesel‘s given his sizable social media following a sneak peek. The Fast & Furious star debuted a teaser for September’s Riddick, the third film in Diesel’s other hit Universal Pictures franchise. “It’s been over decade, since I’ve been to Comic-Con…,” Diesel posted to his Facebook page. With a whopping 43M followers, he’s one of few stars whose own Facebook pull eclipses that of entire movie studios. David Twohy (Pitch Black, The Chronicles Of Riddick) returns to helm the threequel. Comic-Con’s 2013 edition runs July 18-21 in San Diego.
