There seems to be some discussion whether this film is a horror or a thriller, although I would label it a psychological thriller. But who cares-it's a very powerful film which should not be labelled into a particular genre.
It is beautifully shot in the unlucky, fated Dakota buildings, New York which in real life is used to terrible events - John Lennon was murdered outside in later years.
Mia Farrow plays the central character Rosemary. It is an excellent, controlled performance. No histrionics- she is just compellingly vulnerable. She later helps narrate the making of movie in the special featurette which is also made in the sixties-it is a great period peace as she extones the values of love and peace having just hung out in India with the Beatles. It is unintentionally hysterical!
Her boyfriend in the movie is chillingly cold, at one one point shrugging his shoulders when he admits to making love to her when she was asleep. In fact, all the cast is excellent- I particularly like the oversolicitous next door neighbour, an Oscar winning performance by Ruth Gordon.
My favourite scene has to be when Rosemary phones her doctor from the phone box. She is delirious at this time- but we still don't know if she is paranoid or there is a plot against her.
I like the attention to detail-ie the pictures on the wall in the apartment, the babies presents wrapped up in black ribbons, the abundance of crosses and herbs.
I don't know if people would enjoy it if they expect it to be scary. I think it is is very interesting in a dark way, quite chilling. It does not have alot of special effects unlike most 'horror' movies. I don't like films with a lot of special effects as I prefer actors to computors- maybe more films should be art, not science. This films makes you use your imagination, and you will probably have to watch it twice to pick up on some of the coincidences and stranges nuances that occur.
I really enjoyed the film and would recommend it.
