The Dialogue An Interview with Screenwriter David Seltzer: David Seltzer knows Hollywood. He knows the business, the tricks of the trade and all the hidden truths. He's got the stories from working with Jacques Cousteau, penning the horror classic The Omen and adapting Roald Dahl's Willy Wonka and the Chocolate Factory. He can tell you why writing is like love-making and why there is no such thing as fiction. His advice about directing? Wear comfortable shoes. In this interview, you'll learn that and more, including what recent screenplay is the most elegant he has ever heard spoken on-screen and why you don't win arguments with movie stars.
