In the Dark Knight Batman (Christian Bale) gets darker; as does his nemesis Joker (Heath Ledger). The Joker is without scruples. He kills even those who for him or with him. As such he takes over the crime syndicate in Gotham. He does behave in conventional ways, and this throws Batman off. Also the district attorney, Harvey Dent (Aaron Eckhart) is being aggressive going after organized crime. The assistant is Bruce Wayne's interest, Rachel (Maggie Gyllenhaal). Joker is very good at getting what he wants. He takes on the task of killing Batman. He fails to do this but he does turn turn Dent. He kidnaps he and his fiancé, Batman's friend Rachel. He forces Batman to save one of them, and Rachel is killed. Dent is left as Two-face. Two-face ends up dead and Batman takes the blame so the people can have a hero in Dent, and the laws against organized crime go into effect. At the end of this movie Batman becomes the Dark Knight and goes into hiding.
The Joker is really devious and evil, and always seems to be a step ahead. Hedger plays him very dark. Michael Cane continues as Alfred the butler and support Wayne and Batman. Gary Oldman continues as commissioner Gordon. It is Batman and the commissioner who decide the perception has to be that Batman is evil and Dent is a hero. Joker had messed with Gordon and his family, kidnapping them.
