I saw a movie a while back and I can't remember the title and it's not a popular movie so I can't find i through description either. It's about a mad scientist who brings the dead back to life but they turn as cannibals. The movie starts off with him doing this experiment on a frog. He poses as a doctor and tests this experiment on many of his patients including his wife and daughter. If my memory serves right, eventually the wife and daughter eat the scientist which causes the experiment to break out throughout the hospital. I remember that it ends with a woman being pregnant with a baby infected by the scientist's experiment.This movie is extremely gory. Please help!
