Other mistake: There are at least three mistakes/errors in the scene where Kris is hit by the car. First of all, the image is evidently sped up during the collision. Then, when Kris gets up after the collision, there are three green trash bins in front of her which did not appear in the previous shot. Finally, it is physically impossible that those three trash bins can still stand after being hit by a car. (00:03:40 - 00:04:20)
