Having been an actor and a writer for so long - 20 years or so - I felt that it would be daft to go to one's grave without having directed. It's a natural extension of writing and acting, and so I knew it would happen one day.
The bottom line is if the movie does well, everybody is happy and they forget about what they went through. And if it doesn't, it's 'I told you.' There's one director who I won't mention, who said, 'it's all blood under the bridge.'
