I enjoyed reading _Nobody's Fool_. As I was reading it, I couldn't help but picture Jack Nicholson playing the part of Sully. In fact, to me, the rascally Sully *was* Jack Nicholson. This idea popped into my mind, spontaneously and unbidden. In fact, I expected everyone who read the book to have the same idea. A short survey proved me wrong. That puzzled me because I was convinced that the choice of Nicholson would be obvious to everyone. So I was a bit disappointed when Paul Newman was chosen to play Sully in the movie. Even though I love Paul Newman, it seemed to me that he portrayed Sully in a quiet, low-key manner. I had pictured Sully as more of a lively and lovable rascal. To this day, I wish that I could see how Jack Nicholson would play Sully. I'm still looking for someone to agree with me.
BTW, this was the first and only time, while reading a book, that I imagined a specific actor in the part of the protagonist.
