Directed by: David Fincher
Starring: Ben Affleck, Rosamund Pike, Neil Patrick Harris, Missi Pyle
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.
Plot hole: Amy calls the Police about the shed before going to Desi. They watch Nick's TV statement together. The shed is only searched by the police after the statement. Which would imply the police sat on the report for several days before investigating.
Continuity mistake: Some scenes were shot after Rosamund Pike had gained some weight, following the plot of the book correctly. However, they were edited together very badly, so that the extra pounds (most visible on her face) come and go several times during the montage showing what she did during the first two days of her "kidnapping." Pasty face with puffy cheeks, and sleek face with taut skin over jutting cheekbones switch back and forth in what amounts to a matter of hours in the film's plot.
Chosen answer: That may have been what she was doing. Amy was attempting to make it look like she'd been repeatedly raped by Collins, so she was doing various things to herself, like using a bottle to self-inflict trauma onto her privates to look like forced sex.
