As the big-screen adaptation of Gillian Flynn's "Gone Girl" gears up to hit theaters on Oct. 3, director David Fincher is dropping off some clues for the Internet to devour, just like the ones Amy leaves Nick on their anniversary. This particular photographic evidence, exclusive to HuffPost Entertainment, features the central couple (played by Rosamund Pike and Ben Affleck) celebrating their wedding night with friends and a champagne toast. The photo is placed inside an evidence bag, hinting at the mystery that's to unfold surrounding the pair. The image teases a new trailer that 20th Century Fox will release on July 7.
