I wrote a draft of 'Playboy' for Warner Brothers, and it was impossible to really be independent of Hugh Hefner. In the end, Hugh Hefner was unable to take the back seat required to be able to write something about him that I felt I could do.
I can't help slightly falling in love with every character I write about. And I quite like writing about people who are vilified.
As historians write more and more histories, it's a sort of self-fulfilling prophecy that other historians read their histories and then make synthesis, and certain things just get forgotten and left out and neglected.
The film 'The Queen' came about with a producer saying to me that he wanted me to write about the circumstances behind Diana's death. I think he was hoping that I would come up with some journalistic scoop that would identify an MI5 covert plot.
I wrote 'Hereafter' quickly and without mapping it out too much or being too schematic. As an exercise, I think that was incredibly important.
The real beauty in my professional experience has been friendships and collaborations with filmmakers.
