 SYNC: In the scene where Marla is trying out in the gym and she hits  the ball though the window you can tell that the ball is going  though two different windows. The first shot is from inside the gym  and the ball breaks through the window at the corner of the building  in a direction towards the corner of the building. The next shot is  from outside the building and the ball is not coming out of the  corner window, but the window next to it, and not in the same  direction as the ball was hit from inside the building. The angle at  which the ball came out of the building would never be possible from  where Marla was hitting the ball.
