Well I had this batman book out from the library out a few years back, it was published in 1988 right before Batman went into production and the end of the book talks about how Batman will live forever because Tim Burton was making a Batman movie and he wanted Jack Nicholson for the Joker and either Michael Keaton or BILL MURRAY to play Batman.

It certainly would have been different. I kind of would like to see that, mainly for Murray's Bruce Wayne. I'd just like to see him say "Because I bought it in Japan" while flirting with Kim Bassinger.
