Peter Bart has an interesting article on the new JOKER movie and how the legend of the Joker was built by the $50 million deal that Jack Nicholson got in the late 80s during production of the film.
From the article:
No one who was on the set will ever forget the day The Joker freaked out. With his face frozen in grotesque makeup, he suddenly started screaming that his deal was fraudulent, his director was unprepared, his dialogue was stilted and he was quitting the doomed show. He kept shouting expletives for over two hours to anyone who would listen, then marched off the set.
