Dr. Martin: Working with the mentally disturbed... can lead to a breakdown.
Dr. Rutherford: If you can recognise who is - or was - Dr. Star, then I'll consider you qualified for the position.
Other mistake: When the wrapped body parts are going for the mistress (the one telling the story), you can see the right arm dragging itself across the floor. However, the arm that grabs her face from above is also a right hand. How did the murdered wife have two right arms?
