20 Things You Didn't Know About Gone Girl
5. Ben Affleck Researched Actual Wife Killers For The Role
Despite the fact that Nick isn't in fact guilty of killing Amy - because, of course, she isn't really dead - Ben Affleck nevertheless researched a number of real-life criminals convicted of killing their wives.
He especially fixated on Scott Peterson, who in 2004 was convicted of murdering his heavily pregnant wife, Laci Peterson, and actually bears a relatively decent physical resemblance to Affleck himself.
It's an interesting tactic on the part of Affleck to help throw viewers off for the first half of the movie and keep them distrustful of Nick until the big reveal finally happens.
