"Rosemary's Baby'," he asserted during production, "is the most violent, non-violent picture I've ever worked in. It reeks of mystery, horror and eeriness, with never a blow being struck . . ."

The only way they can gauge their careers is by their paychecks and their most recent notices. Actors are babies." Mia said her most prized possessions are her deaf cats, always with her on the set, and her retarded dog, kept at home, who is always bumping into the walls. Mia made some great friends with the crew of the picture but was nervous about those visitors who got on the closed set. She is actually a very shy girl, just beginning to come out of her shell.
