Directed by: David Fincher
Starring: Ben Affleck, Rosamund Pike, Neil Patrick Harris, Missi Pyle
Revealing mistake: In the scene with the games console the controller isn't on and it is either not attached to a PS3 or the PS3 is off. You can tell because if the controller was on there would be a solid red light and even if it was just charging there would be a blinking red light.
Revealing mistake: When Amy kills Desi, we can see his neck move, meaning he's breathing.
Plot hole: SPOILER: When Amy comes back, doctors would have checked her non-existent head wound from the "abduction", from where she supposedly lost that much blood. That would and should have revealed all of Amy's lies.
Trivia: Tyler Perry was reportedly not aware of director David Fincher's body of work, and was cast without knowing Fincher was directing. Perry has stated that he likely wouldn't have taken the role if he knew about the darker work Fincher is generally involved in, but stated that he was glad he did take the role in the end.
Question: Why does Amy whack herself in the face with a hammer? Her plan is working at this point. She's achieved anonymity and escaped her life. What possible good could cover from hitting herself in the face with a hammer? (01:13:04)
Answer: To my knowledge, the purpose of hitting herself was two-fold. First of all, a facial injury would support the idea that she was abused or in some sort of bad situation. And secondly, to help mildly alter her appearance, so she could blend in more. (Especially considering people were looking for her).
