Ben Affleck recently stunned fans taking a tour of the Warner Bros. Studios lot in California by making a surprise appearance in a Batmobile. The actor, who portrays the Caped Crusader in the upcoming Batman v Superman: Dawn of Justice movie, stunned tourists as he popped open the car door to reveal his presence, prompting one woman to ask, "Are you real?", to which the star responded, "I am real!" The stunt was filmed as part of a charity drive on Omaze.com to offer devotees the chance to win tickets to the film's Hollywood premiere in exchange for a $10 (£7) donation. Proceeds will benefit a trio of good causes, including Affleck's Eastern Congo Initiative, works to create economic and social development in the war-torn region.
