Christian Bale thinks Batman is "not a healthy superhero".
The 38-year-old actor reprises his role as the Caped Crusader and alter ego Bruce Wayne in 'The Dark Knight Rises' and says the movie finds his character in very poor shape.
He said: "He's filled with remorse, he's become a recluse, he's given up and completely quit.
"He's in very poor health physically and mentally.
"He is not a healthy superhero. He has multiple-personality disorder and is a very sad, lonely individual."
Christian also admitted he thinks his character could be a "villain" if it weren't for the altruistic side of his personality.
He added to the Daily Telegraph newspaper: "He has the public persona of the playboy and the character of Batman is the personification of his rage and sense of injustice.
"He's almost a villain and takes it to the edge, where he can do no wrong, but he has this altruism holding him back from doing that.
"The reason he dresses in the Batman suit is that he feels monstrous, so he creates a monster to represent that rage and keep it away from his own personal life."
