Towards the end of the movie when Claire is running along the road, the shadows on the ground are initially from the right, then with the patrol car the shadows are from the left and finally with Claire and the cop talking, the shadows are from the right again.
The final shot of the patrol car driving away has been flipped as can be seen by the reversed 911 notice on the back of the patrol car and the transposed positions of the red and blue flashing lights.
