Bruce Wayne, also known by his superhero vigilante persona Batman, is a fictional character who is the main protagonist in Christopher Nolan's trilogy of superhero films, based on the DC Comics character of the same name, created by Bill Finger and Bob Kane. Portrayed by Christian Bale, this version of Batman is arguably explored more in-depth compared to that of the previous film series by Tim Burton and Joel Schumacher, as the Dark Knight film series provides a full arc for the character and was intended by Nolan to be more realistic than previous portrayals.
