The 1989 Batman. Michael Keaton was angry because the costume was torture to wear. The films script kept getting reworked during production. During production, the movie still didn't have an ending. So when Nicholson was walking up the Cathedral steps for the big finale, he asked Tim Burton why he was going up the steps. Burton said "We'll figure it out when we get to the top". Nicholson also supposedly said to Kim Basinger "I'm gonna kill that guy whose dick you're sucking", meaning Jon Peters. A good time was had by all.

It's a decent read, but by far the material on Peters is more intriguing.
