So Joe Cornish, director of the excellent Attack the Block, is directing the adaptation of Neil Stephenson's classic cyberpunk novel. On the other hand, the producer, Kathleen Kennedy, was one of the people backing The Last Airbender. Will Hiro Protagonist, the biracial lead character, end up whitewashed due to producer pressure, or will they be willing to stick to the book?
