"Gone Girl" author Gillian Flynn participated in a Reddit AMA on Tuesday, April 22, and responded to questions about the book's ending being changed in the film adaption. She reassured fans that the finale wouldn't change as much as she had once suggested.
In January, Flynn hinted that the movie's ending would be much different than the book's. She told Entertainment Weekly, "Ben [Affleck] was so shocked by it. He would say, 'This is a whole new third act!'" Flynn wrote the screenplay and according to the interview, she was quite excited to take apart what she had written years before. "There was something thrilling about taking this piece of work that I’d spent about two years painstakingly putting together with all its eight million Lego pieces and take a hammer to it and bash it apart and reassemble it into a movie."
But Flynn's most recent answer on Reddit makes it seem that the changes won't be so dramatic. See her full comment below:
Tell your girlfriend not to worry—those reports have been greatly exaggerated! 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. But the mood, tone and spirit of the book are very much intact. I've been very involved in the film and loved it. Working with David Fincher is pretty much the best place to start for a screenwriter. 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.
The most recent trailer for "Gone Girl," which debuted last week, gives away nothing about the ending, but it does feature a pretty killer use of "She," covered by Richard Butler.
"Gone Girl" is out in theaters on Oct. 3.
