Re: Heath ledger Joker and Harley Quinn
The only way Harley Quinn would work in the universe Nolan constructed is if she was characterized as she was in Birds of Prey: as a Moriarty-like psychologist manipulating behind the scenes. The moment she starts behaving like a kid as she did in TAS, the illusion is broken.
"Johnny Storm's a good-hearted kid, sure, but he has the attention span of a toaster, and he leads with his face; in Johnny's undisciplined mind, there's only a single synapse between thinking and doing. The Avengers' battle cry is "Avengers Assemble"; the Fantastic Four's is "Johnny, WAIT!"----Mark Waid
