Last night on the Late Show, David Letterman might have stoked the wrath of Christopher Nolan with his off-the-cuff commentary on The Dark Knight Rises. "It's not essential to watch previous installations of Batman, and I think this is it," he told his guest, Anne Hathaway. "And in the end, Batman is dead."
