Steven Spielberg's sci-fi horror movie Night Skies; David Lynch's Ronnie Rocket, Terry Gilliam's Watchmen; and Ridley Scott's I am Legend - these are just some of the legendary sci-fi films covered in this book. Legendary because none of them ever actually made it to the screen. Drawing on many interviews with the film-makers involved, this volume tells the tortuous stories of the films that never were, and reveals the details of what we could have seen. The Thunderbirds movie; Aliens versus Predator; James Cameron's Spider-Man and Avatar; Stanley Kubrick's Childhood's End; Kevin Smith's Superman Lives; and Philip Kaufman's Star Trek: Planet of the Titans - all these projects and more are covered in this book.
