Entertainment Tonight has unveiled the first footage from David Fincher's “Gone Girl” which is based on the bestselling mystery novel by Gillian Flynn, according to TheWrap.

Ben Affleck stars as Nick Dunne, who comes under suspicion when his wife (Rosamund Pike) disappears.

In this 20-second tease for the upcoming trailer, Nick maintains his innocence, saying “I did not kill my wife. I am not a murderer.”

The atmospheric footage hints at what Fincher has in store for audiences. The last time he adapted a bestselling novel was “The Girl With the Dragon Tattoo.”

Tyler Perry and Neil Patrick Harris co-star in “Gone Girl,” which 20th Century Fox will release on Oct. 3.
