In David Fincher's captivating new thriller GONE GIRL, Ben Affleck and Carrie Coon play twins Nick and Margo Dunne, and a more believable brother-sister relationship is rarely executed on screen. They bicker, they console, they forgive; Affleck and Coon's chemistry brings some much needed humanity into a film where cynicism, deceit and manipulation run rampant. (Although those aspects of it are much fun, of course.) The fact that one is an A-list movie star and the other is essentially a complete unknown doesn't matter when they're trading barbs in the film; they're equally matched in every way.
Affleck you know, and the two-time Oscar winner gives what may be his best performance as the tormented, and slightly suspicious, Nick, a man accused of making his wife disappear. But Coon is a revelation; in her first feature film, the actress best known for her work on the stage and, more recently, small screen (she's a regular on HBO's "The Leftovers") steals most of her scenes as the sardonic Margo. It's a safe bet most people will leave the film wondering just who that was playing Nick's sister, and where they can see more of her.
I sat down with Affleck and Coon to talk about that special dynamic between them, working with David Fincher (with his 40 takes per-scene) and dealing with the media circus, in the film and in life.
