"For me," he tells E!, "as a very big Diana fan and all of her charitable work and how she handled herself, I was always very interested in that story of divorce and pain and I think that this show Feud can show a lot of two-hander feuds in a different way. The first season Bette and Joan is a Hollywood story. I wanted to do a different kind of feud that's about broken hearts. And I think that's what that marriage was and that's what Charles and Diana is about."
