Back in April we got our first look at the first trailer for David Fincher‘s new film Gone Girl. Today we get to check out the just-released second trailer for the film. As you can see above, we get a much better sense for the movie overall from this trailer … and we get to hear the first bit of music created for the film by Trent Reznor and Atticus Ross. It looks good and mysterious, I think. Have a look, see what you think. Gone Girl hits theaters on October 3.
