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.

(00:03:30)
Continuity mistake: When Damien (Walker) is driving the prison van he hijacked, through Brick Mansions, the steering on the van locks up, resulting in a close up of him shaking the steering wheel trying to free the steering.
