Even though neither actor is alive, one author who claims to have interviewed Marlon Brando for a book about Paul Newman says that in the interview Marlon gave that he outed both himself and Paul Newman. The book is entitled Paul Newman: The Man Behind The Baby Blues and is by an author named Darwin Porter who is allegedly obsessed with the sex life of Paul Newman and has spent years trying to establish every person with whom Paul Newman had sex. In 2004, Porter interviewed Marlon about his experiences with Paul Newman. "He never fooled me. Paul Newman had just as many on-location affairs as the rest of us, and he was just as bisexual as I was. But, where I was always getting caught with my pants down, he managed to do it in the dark."
I hadn't realized that Marlon was getting caught with his pants down when it came to being with men. I really need to read more. I also didn't know that when Paul and Joanne got married that they lived with her then ex-boyfriend Gore Vidal who was bisexual. Interesting stuff. I love the old items from Hollywood.
