Starring Mia Farrow. Once married to nortorious Hollywood pedo Woody Allen (who continues a successful carreer as a director today).

I can't tell you how many times I have brought this up in comments. My take is that it's the cast of Rosemary's Baby that we're dealing with. These are nice people on the surface. People you think you know and that you can trust. That's what the film portrays. They normalize their adherence to evil.
