These latest pictures show the unhappily married pair, as well as Fincher directing Rosamund Pike in what looks to be an underwater scene (hence the motion capture headgear, which will no doubt allow for watery wavy hair to be added in post production) and a table read shot of Neil Patrick Harris (How I Met Your Mother) as Amy's ex Desi with Carrie Coon (The Leftovers), who plays Nick's sister Margo.
Fincher promises us that this is a date movie that will "end 15 million marriages", and while we can hope he's wrong about that, we're definitely in for a discomfiting ride.
Adapted from Gillian Flynn's bestselling novel, a former journalist and author herself, Gone Girl finds Fincher firmly in dramatic thriller territory, with the story of how the outwardly perfect marriage between Nick (Ben Affleck) and Amy Dunne (Rosamund Pike) has crumbled in the light of her disappearance. With Nick trying desperately to galvanise the locals of their small town in the search for his missing wife, the finger of suspicion begins to point towards him.
Says Affleck, "I actually think this is the perfect date movie, not because I think it'll result in divorce – I think that's just David's fantasy – but because it's the kind of movie that a husband and wife could talk about afterwards. I think a man and a woman would have different takes on what happens. The last time I was in a movie that I thought polarised men and women in an interesting way was Chasing Amy. That was quite some time ago."
And what does Rosamund Pike think it's all about? "That aspect of marriage as a con game, or whatever. The idea that we perform a sort of ideal version of ourselves that the other person wants. We perhaps belie our true nature in order to perform to the ideal. David and I talked a lot about living in an age of rampant narcissism."
There haven't been too many marriage thrillers in recent years, so this should feel fresh. Ben Affleck will looking to bring his Academy Award® winning gravitas to the role, while we're looking forward to seeing Rosamund Pike firmly and deservedly back in the limelight.
It's also certainly perfect Fincher terrain, as anyone who has seen The Game (1997) and Panic Room (2002) will testify. We're promised a suitably complex thriller that even boasts an altered ending dreamt up by Fincher and Flynn, plus a cast that also boasts Scoot McNairy (Argo), Kim Dickens (The Blind Side), Patrick Fugit (We Bought A Zoo), Missi Pyle (The Artist), Tyler Perry (Alex Cross) and Sela Ward (House M.D.).
Gone Girl hits screens on 3 October.
