There’s no denying that Rosemary’s Baby is one of the scariest and creepiest movies ever made. The first time I saw it, I was up “late” with my mother, who was waiting for my father to come home from a night shift, and it was on TV. I don’t know how old I was—young—but even if I didn’t exactly get what was going on, I certainly got the gist of it and that was enough for it to be, well, fucking frightening.

The whole friendly old people and Satan routine was a new one in screen horror and when you throw in those primordial maternal fears of a pregnant woman, holy shit is that film intense. Rosemary’s Baby is an evergreen movie masterpiece. It’s a film for the ages and will still be watched as long as the human race exists. It’s a perfectly cut cinematic diamond.

This fascinating time capsule piece “Mia and Roman” was made soon after the film had wrapped production—this isn’t a made for DVD extra produced decades later—and features tons of behind-the-scenes footage. Polanski discusses how supreme attention to the smallest details are of paramount importance to him as a director and describes how he likes to watch the actors block out their scenes without any suggestions from him before he decides where to place his camera.

We also see Polanski driving race cars and fencing. Farrow lists all of the animals she has in her menagerie and spouts some “love and peace” stuff that she’d learned hanging out at the ashram with the Maharishi and the Beatles. Farrow says that she and Polanski just “groove together” and he (very sincerely) praises he professionalism as an actress to the hilt.

Krzysztof Komeda’s haunting score for the film is used throughout. Komeda would die from a head injury not long after completing work on Rosemary’s Baby.
