Film has a fairly tight script which, in first half at least, builds up scary tensions nicely. There’s a performance by Mia Farrow which is somewhat reminiscent of Rosemary’s Baby, and enough supernatural trappings to please those who are fascinated by the occult.
Yarn uses all the old warhorses of the genre: the creaking stairs, the throbbing eerie music at moments of mounting danger, a gloomy house in rainy Kensington, the mysterious light that is turned on and off, a seance, and the close-up of the heroine climbing the lonely stairs of a deserted house.
Pic gets off to a running start as an American family’s daughter suddenly chokes at breakfast on a piece of apple. Though mom (Farrow) tries to save her by cutting open her throat with a kitchen knife, the daughter succumbs to the apple. After a couple of months in a London hospital to get over the shock, mom goes and buys an old Victorian house.
The mysterious events then start happening. The plot thickens and starts to become difficult to follow as Farrow’s tinkering British boyfriend is electrocuted in his bathtub.
