Other mistake: During the opening scene, when Maria is walking to the bus stop, she walks past a hotel and then a shop with its door open. If you look through the door of the shop you can see a crowd of people, who obviously aren't paid extras, looking through the door watching filming. (00:01:28)
Other mistake: In the beginning, when Angela is chasing Maria, she is running and screaming. Yet, all the people around, seeing and hearing this, do nothing.
Other mistake: At the beginning of the film, there's no way Angela would possibly have been able to know the exact moment the girl would have been walking down the street and what she'd be wearing so she could be wearing the exact outfit.
