Gone Girl Author Insists Reports Of A New Ending For The Movie Have Been ‘Greatly Exaggerated’ The author of smash hit novel Gone Girl has insisted that reports implying the movie adaptation of the book will have a completely new ending have been “greatly exaggerated”.Gillian Flynn’s novel has been adapted for the big screen by acclaimed director David Fincher, with Ben Affleck and Rosamund Pile taking on the lead roles. The author has also been heavily involved in the project and earlier this year made some comments that suggested she and Fincher had come up with a whole new ending for the film.“Ben [Affleck] was so shocked by it. He would say, ‘This is a whole new third act! She literally threw that third act out and started from scratch,’ ” the author herself told EW.Flynn has now said she didn’t actually mean she’d penned a whole new ending for the tale of a husband who becomes the prime suspect after his wife mysteriously disappears on their wedding anniversary. In a new Reddit AMA session yesterday, the author has set the record straight.“….those reports have been greatly exaggerated!” the writer insists, adding that what she meant was that changes have had to be made in order to transfer the story from page to screen.Ben Affleck stars in Gone Girl (Twitter/20thCenturyFox)“Of course, the script has to be different from the book in some ways—you have to find a way to externalize all those internal thoughts and you have to do more with less room and you just don’t have room for everything,” she explained. “But the mood, tone and spirit of the book are very much intact. I’ve been very involved in the film and loved it.”Of her time with Fincher, known for his exhaustive approach to filmmaking (reports of fifty takes per scene came back from the set), Flynn is full of praise. “Working with David Fincher is pretty much the best place to start for a screenwriter,” she gushes.“Screenwriting definitely works different parts of your brain than writing a novel. I do love that with novels, you can really sprawl out—it feels quite decadent. With screenwriting, you have to justify every choice. It’s a nice discipline, but definitely not decadent.”Gone Girl is released on October 3.
