I wanted to know as much as possible. It was something that Jane encouraged. She said to me, ‘You’ve got to become our expert on John Keats so that if anybody has a question about him or his work, you can answer it.’ And I took her word. I kind of did become a bit of an expert. I read everything I could get my hands on, about him. I read about four biographies and all of his letters, all of his poetry, obviously, and then kind of critical studies—stuff that wasn’t even especially pertinent to the film, but I got kind of carried away and really addicted to knowing more and more about him.
