Twentieth Century Fox has unveiled four new posters for its upcoming “Gone Girl,” unveiling clues about the film’s mystery and teasing a new trailer.

In the movie, based on Gillian Flynn’s best-selling novel of the same name, Ben Affleck plays Nick Dunne, the prime suspect in his wife’s mysterious disappearance on their fifth wedding anniversary. His wife, Amy Dunne, is played by Rosamund Pike.

One poster contains a wedding photo of the two, contained in a bag labeled “evidence.” The tagline “Happy Anniversary” adds to the eerie tone.

The three additional posters contain mementos that reveal clues to Amy’s vanishing, including a red thong, a bit from her diary and a scalpel.

The posters also reveal that a new trailer for the David Fincher-directed pic will drop July 7. The first trailer was released back in April.

“Gone Girl” is set to hit theaters Oct. 3.
