Will Ben Affleck be a good Batman? When Ben Affleck was first announced as Batman, their was controversy over whether or not he would be a good Batman. The same thing happened when Christian Bale was first announced as Batman because people thought it was weird since the actor has a Britsh accent and was very skinny because of the role he was playing in his last movie. To change this, Bale had to gain 60 pounds to make him self look buff. Ben Affleck is a very talented actor with receiving more than 30 awards including "Best Supporting Actor".
