Re: Christian Bale v.s. Michael Keaton - Part 2
Burton just wanted to give him a greater reason to hate Joker and make it all relate. Nolan basically did it via inspiration from most of the books by having them relate due to Joker being obsessed with Batman and viewing him as a lifelong yin to his yang.
It's better to be seen than viewed.
Who the **** makes a movie and while planning it is like, "you know what this needs...is some Greg Kinnear."
