Christian Bale hasn’t shut the door completely on playing Bruce Wayne/Batman for a fourth time on the big screen. There’s just one stipulation: Christopher Nolan must direct. The Oscar-winning actor recently told ScreenRant that he’d put on the Dark Knight’s cape once more as long as Nolan’s back in the director’s chair. Nolan directed Bale in three Batman movies, with “The Dark Knight” and “The Dark Knight Rises” both grossing over $1 billion at the worldwide box office.
