Back in January, David Fincher mentioned that the ending to his film adaptation of Gone Girl would have “a whole new third act.” This excited a lot of people (the book’s ending was, by many, not so well liked) and outraged others (*hand raise*). However, Gillian Flynn, the book’s author, later told Reddit that Fincher’s description of the changes were “greatly exaggerated.” Not that there were no changes, just maybe scaled back from Fincher’s ‘burn it down and build anew’ version.
In an interview with EW, Fincher was asked point blank what had been changed, and his answer — “Everything and nothing” — was less than enlightening. When asked to elaborate, he went with the corpsiest metaphor he could think of.
“You’re not changing the marrow of the creature,” he says. “You’re just changing the bone structure and the muscles and the skin.” Pause. “And the hair.” He laughs. “It’s all of its outer sheathing. But at its core, it’s exactly what I think Gillian always intended.”
