Philip Pullman: Storyteller
Robert Butler's interview with Pullman is full of fascinating details, from how he wrote the book (three pages a day, no more, no less) to why he won't debate his work with fundamentalists ("You can't communicate with people who know they've got all the answers").
Oh, and casting Nicole Kidman in The Golden Compass? That was Pullman's idea. He admits he was wrong about making her character a brunette, however. "You sometimes are wrong about your characters. She's blonde. She has to be."
