Don’t believe what the people in Hollywood say! [laughs] Do not believe these people, these people do not speak truly. They tell you that they admire your work so much, and you’re going to have all the input over it and so on. Forget it. You don’t have artistic control. Nobody but Rowling ever got artistic control over a film made from their work, and she got it because she’s so wealthy. You’re not going to get it. Therefore you have to think: Do you mind if they make a travesty out of your work? Is the money worth it to you? If it is, go for it. Take the money and run, as whoever it was said. If it’s not worth it to you, just run away.
