I re-watched Rosemary’s Baby (1968) again right in time for Halloween and always get a kick out of the Hammer film connection of sorts:
What I mean is when Mia Farrow’s character meets Terry Gionoffrio (played by Angela Dorian) in the launderette and tells her that she looks just like actress Victoria Vetri… who we of course all know as the blonde bomb shell from Hammer’s pre-historic epic When Dinosaurs Ruled the Earth (1970, i.e. produced two years after Polanski’s master piece).
The joke is of course that Angela Dorian (who was that year’s Playmate of the Year after being the September 1967 Playmate of the Month) is none other than Vetri herself!
The actress/model was born Victoria Vetri, though for the first part of her career had decided to choose a pseudonym based on the ill fated liner, until she gradually moved over to her birth name.
As for other cameos: Also watch out for producer William Castle who turns around in the telephone scene where Mia Farrow believes him to be Dr Sapirstein (played by Ralph Bellamy).
As for the film itself: What’s there to say? It’s just one of the great and influential horror movies that just have to be checked out.
