Other mistake: Geena Davis has her hands and feet tied to the water wheel when she's being tortured for information. Under water she manages to free one of her hands but not her feet, when she comes up for air and shoots her captor, she drops the gun and unties her other hand, but her feet are still tied, so she would have fallen face first into the water.
