At the Toronto press conference for the upcoming Guy Ritchie crime flick RockNRolla , Superhero Hype asked Gerard Butler if he'd heard anything more about the recent rumors of a prequel or sequel to his blockbuster action movie 300 that have come to light in recent interviews with director Zack Snyder and the producers. Unfortunately, Butler hasn't heard anything more then we have, and he seemed rather dubious of the film's franchise potential.
