We can't get enough of Ben Affleck and we can't wait for Gone Girl to hit theaters this October, so obviously we were on the edge of our seats when we saw the latest trailer today!

In the two-and-a-half-minute clip we see Ben's character Nick Dunne acting both lovey dovey and borderline violent with his wife Amy (played by Rosamund Pike), and we also get our first peek at Neil Patrick Harris as Desi, Amy’s creepy ex-boyfriend.

As you may know, David Fincher directed the big screen adaptation of Gillian Flynn’s bestselling novel, which follows Amy Dunne's disappearance and all the chaos that ensues when her husband is pinned as the prime suspect. Of course, those of us who have read the book know that the plot has a number of twists, and we're curious to see how different the ending is. Apparently it strays a bit from Flynn's original story...

Check it out the new teaser above!
