Forgive me if my memory of the 1989 Batman movie with Michael Keaton is a bit fuzzy, but I seem to recall he had some horrible freak accident that caused his face to get all... white... and so he seeks revenge on Batman, not that he was a mild-mannered citizen beforehand, but... yeah, I guess he was always mad. But Heath Ledger's Joker was even madder.
