After his dead body is hung in the closet, the actor portraying George (Stubby Kaye) can be seen breathing.
When Lana swings the statue to hit George on the head, her arm is shown swinging in a trajectory that is several feet away from him. She could not possibly have hit George with the motion shown.
At approximately 19:20 when Lana is talking to George who is sitting on her bed, the shadow of the boom mic drops down on the wall behind her. It then pulls out of the shot only to drop down again.
