Deliberate mistake: During the interrogation scene, a patient asks for a glass of water. When she receives a the glass of water, she lifts her right hand to her mouth and makes a drinking motion, but is not holding a glass. A moment later she sets down an empty glass with her left hand. When the camera angle changes, the glass has become half full. This implies the patient's mental instability and adds to the surreal feel of the film.
