Human nature stays the same, the one thing that stays constant, like death and taxes. And people still want good stories!
I am no expert on tax; I'm a film producer. I read books and think about which ones would make good movies, and then I work with directors in order to make them.
With 'Suffragette,' I felt that a female writer would be good, and considering the subject matter, who would be better to write the script than Abi Morgan? She was the first choice, and she happens to be a woman.
