Watch: New 'Gone Girl' trailer ups the creep factor with Neil Patrick Harris as Desi

If you didn't get creeped out after watching the first trailer for 'Gone Girl' by Ben Affleck and Rosamund Pike, you will, after watching the second one. While the first one had a haunting rendition of the popular song 'She' by Richard Butler, this trailer has Neil Patrick Harris as the creepy ex-boyfriend. The film, which is set to hit the theatres in October, has been directed by David Fincher.
