I got the Batman and Batman Returns special edition DVDs (there's a sentence I thought I'd never write).

Both of them have lots of cool extra features with talking head patter from many cool comic writers, etc.

Sam Hamm for example, admits that when he first met Burton they both agreed to approach Bruce Wayne as if he was completely insane. The character's arc for the first film is then about "a man who finds a woman he loves and must overcome the fact that he's slowy going *sane.*"

Awesome.

Alex Ross says he prefers the Burton Joker origin over the Alan Moore Joker origin.

Paul Dini give props to Burton and whoever wrote Returns (I forget the guy's name) for creating Max Schrek.

The costume designer and costume makers on Returns spend a good five minutes gushing over how amazingly awesome Keaton's costume looks in the film.

Bruce Timm says his favorite part of Returns is the very beginning, when Wayne is sitting all alone in his mansion.

Dini loves the penguin funeral procession.

Either Timm, Dini, Ross, or Frank Miller (I can't remember which) points out that Keaton is an inspired choice because he looks like the type of guy who really needs to wear a batsuit in order to scare people.
