Audio problem: In the scene where Miranda is at her home looking at the photo of her and her husband, she says "why me?" but her mouth does not move. (01:10:55)
Audio problem: After Halle Berry escapes she is driving with two hands on the wheel - but the engine sounds indicate she is changing gears, and the gear stick is seen in previous shots.
Answer: The blood is not from Miranda; the drop of blood is a sign from the "dead girl" to tell Miranda that she should go to the place in the pic. Miranda goes the next day and that's how she finds her husband was a sadist.
