Continuity: At the beginning of the movie, Selena drives her car to the right side of the house. When the shot changes, the car is several feet further back and is now heading across the front of the entrance.

Continuity: When the vortex breaks the window, the sound of glass breaking is heard but no glass pieces are seen. In a later shot, the floor is filled with tiny pieces of glass.
