Continuity mistake: Only Rebecca's left breast is exposed when she is being bitten on the neck. However, both breasts (as well as her right shoulder) are exposed after her attacker is beheaded. She opens her eyes and continues lying on the floor. (00:06:43 - 00:07:05)
Other mistake: Three fingertips are shown dropping to the floor, but there are sounds of four fingertips being broken off. (00:03:33)
