Watch: Intense New Trailer For Ben Affleck’s ‘Gone Girl’

Director David Fincher’s upcoming thriller Gone Girl released a third trailer during the Emmy Awards telecast Monday night.

The eerie trailer showed more insight behind the relationship between Amy (Rosamund Pike) and Nick Dunne (Ben Affleck), giving us a sneak peek of their first meeting and the unraveling of a not-so-perfect marriage.

After Rosamund’s character disappears on their fifth anniversary, she leaves behind a diary and a trail of clues making Affleck’s character look like the prime suspect.

“The man of my dreams. This man of mine may truly kill me,” says Amy over a voiceover only moments before a “Help Find Amy Dunne” billboard appears.

Below is the film’s official synopsis, courtesy of Twentieth Century Fox:

“Gone Girl” – directed by David Fincher and based upon the global bestseller by Gillian Flynn – unearths the secrets at the heart of a modern marriage. On the occasion of his fifth wedding anniversary, Nick Dunne (Ben Affleck) reports that his beautiful wife, Amy (Rosamund Pike), has gone missing. Under pressure from the police and a growing media frenzy, Nick’s portrait of a blissful union begins to crumble. Soon his lies, deceits and strange behavior have everyone asking the same dark question: Did Nick Dunne kill his wife?

The film stars Neil Patrick Harris (who plays Amy’s ex-boyfriend, Desi Collings), Tyler Perry, Kim Dickens, Patrick Fugit, Scoot McNairy and Boyd Holbrook.

Gone Girl, based on Gillian Flynn’s best-selling novel, opens in theaters on October 3.
