It looks like David Fincher has found his "Gone Girl."

Actress Rosamund Pike has "been offered and is expected to accept" the lead role in Fincher's film adaptation of Gillian Flynn's bestselling mystery novel, according to The Hollywood Reporter.

She'll play Amy Dunne, a woman who goes missing on her fifth wedding anniversary, leaving her husband as the prime suspect.

Ben Affleck has already been cast as the husband, Nick Dunne. Per THR, Neil Patrick Harris and Tyler Perry are being eyed for supporting roles in the film.

Flynn adapted the screenplay for "Gone Girl" from her novel. Reese Witherspoon is producing, alongside Bruna Papandrea and Leslie Dixon.

Production on the film will reportedly begin in September.

Pike recently starred alongside Tom Cruise in "Jack Reacher." She's also had roles in films like "An Education," "Pride & Prejudice" and "Die Another Day," and recently shot the dramedy "A Long Way Down" opposite Aaron Paul.
