Ben Affleck to Play the Asshole Husband in the Gone Girl Movie

David Fincher — director of Fight Club, Seven, The Social Network — is helming the big-screen adaptation of Gillian Flynn's bestselling novel Gone Girl, and Ben Affleck has just been cast to star as Nick Dunne, the unemployed husband who becomes a suspect in the disappearance of his wife.

As you may recall (remember our book club?), Gone Girl centers around Nick and Amy Dunne:

a married couple whose relationship becomes strained after Nick loses his job and his income, leading the pair to leave their life in New York City and instead make a living in his hometown in Missouri. Things then take a turn for the worst when Amy suddenly disappears and Nick becomes a prime suspect.

If you read the book, you know that Nick is a terrible, manipulative person, but eventually you find out Amy is even worse. Reese Witherspoon is a producer on the flick, but the part of Amy has not been cast. Any suggestions?
