Continuity mistake: In the beginning of the movie, the doctor invites the two girls knocking on his door inside out of the rain because their car broke down. He gives them both water (laced with drugs). One of the girls knocks her glass over, spilling most of the water, which can be seen as the glass sits on the table. Then when the doctor leaves the room, while the two girls are talking, you can see that the glass on the table magically is filled again.
