Here's a treat for you all. Here's the audio book for Batman Forever. It appears to be an abridged version of the novelisation by Peter David.
The book is read by Rene Auberjonois who played Dr Burton in the film (and is probably best known for playing Odo in Star Trek: Deep Space Nine).
There's a few interesting differences at the beginning. First to note is that it begins with the Danny Elfman theme (I guess Elliot Goldenthal hadn't recorded the score yet?).
Chapter 1: Bruce discovering the batcave as a boy.
Chapter 2: Edward Nygma being bullied as a child at school (reminiscent of his first comic appearence in Detective Comics 140).
Chapter 3: Harvey Dent (pre-disfiguration) waiting for Batman to turn up on the Police Rooftop.
Chapter 4: Dr Chase Meridian getting her purse snatched on the streets of Gotham. Dick Grayson and his father, who happen to be nearby, stop the thief and get her bag back.
The rest of the book proceeds as per the film.
