The new Gone Girl trailer debuted during last night's Emmys.
The clip features a preview of the dark, ambient music composed by Trent Reznor and Atticus Ross, the team who previously scored The Social Network.
It also features a lot of Ben Affleck being confused that people would accuse him of murdering his wife ("You asking me if I killed my wife?") and a brief moment with Neil Patrick Harris as sinister character Desi Collings.
