The world's most-wanted news out of Comic-Con is exactly what role Vin Diesel will be playing in any of Marvel's upcoming films.  What the world gets, for now, is news that Diesel will star in World's Most Wanted, an action-adventure flick from Lair video game writers Will Staples and Sean O’Keefe, who wrote an earlier draft, now rewritten by Dan Mazeau (Wrath of the Titans).  Deadline reports that the Universal Pictures project will reunite Diesel with xXx producer, Neal Moritz.  Diesel will next be seen in the highly-anticipated anti-hero film, Riddick.
