Continuity mistake: Near the beginning when Damien (Paul Walker) is holding onto the back of the vehicle, the guy shoots the rear window and it smashes. All the piece of glass is everywhere on the trunk in front of Damien but in the next shot of him there is no glass to be seen, then next shot again the glass is back. (00:18:12)
Factual error: The "brick mansions" are in Detroit, but when the surveillance satellite footage is shown, the initial, close-up skyline shown from above is of San Francisco. Then as it zooms out it's looking at Chicago. (01:04:00)
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. In the scene they're driving a GMC van but the close up shows a Ford Mustang steering wheel.
Continuity mistake: Thyroid Gland's chain necklace disappears and reappears a few times during the first part of his fight with Damien and Lino.
