Other mistake: Carolyn Stilton shoots Blondie O'Hara in the head and is lying dead over her dead husband. Just before the final scene starts she begins to open her eye.
Continuity mistake: When Miranda Richardson is sitting on her bed after being threatened by Jennifer Jason Leigh, Miranda's blue dressing gown is pulled up on her shoulder. In the next shot it has slipped down. It carries on like that for a few shots.
