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.acmorwin
Continuity mistake: At the very beginning of the movie as the camera pans around to the parked silver Mercedes, the wheels are straight. However, as the camera enters the driver's window to show the Doctor, the steering wheel is turned to the left (note the control buttons and wood effect on the wheel are well out of line from where they would be if the car was going in a straight line).
Dr. Heiter: Do you already regret your little escape? In fact, I'm thankful for it, because now... I know definitely you are the middle piece.
Dr. Heiter: I'm Dr. Josef Heiter, retired, but still very well known as the leading surgeon in separating Siamese twins. Six months ago, I designed a never seen operation, not separating any more but creating. I transformed my three Rottweilers into a beautiful three hound construction. Good news, your tissues match. So, I'll explain this spectacular operation only once.
