20th Century Fox dropped four eerie posters to tease a new trailer for David Fincher's Gone Girl set to come out tomorrow. The posters — evidence bags containing a photo of Amy and Nick Dunne (a.k.a. Rosamund Pike and Ben Affleck), a red thong, a utility knife, and a burnt diary page, all under the heading "Happy Anniversary" — play up the creep factor already established in the first trailer. Of course, the dimly lit drama is an adaptation of Gillian Flynn's bestseller of the same title, about an aggrieved husband whose wife goes missing on their fifth anniversary. Take a look at the "clues" so we can overanalyze their significance!
