Rosemary's Baby (1968)
Rosemary, played brilliantly by Mia Farrow, slowly realizes there's something not quite right about her obstetrician, Dr. Abraham Saperstein, and something really wrong with her unborn child. Her husband is acting suspicious, too. And what's in that nasty drink she's forced to imbibe every day? Featuring extremely creepy neighbors and perhaps cinema's most suspenseful dramatization of consulting a doctor for a second opinion, this '60s horror classic is mostly about what you don't see -- though when the baby finally arrives, he clearly resembles his father.
