The Sentinel (1977) Michael Winner

A fashion model moves into a house inhabited (on the top floor) by a blind priest. She begins having strange physical problems, has trouble sleeping at night, and has some nasty flashbacks of her attempted suicide. She complains to the real estate agent of the noise caused by her strange neighbors, but finds out that the house is only occupied by the priest and herself, and ultimately discovers that she has been put in the house for a reason. 

Winner was a winner (Death Wish, The Mechanic, The Nightcomers) and this film was daring and brilliant. An all-star cast brings to life the story of a young woman with baggage who lives in a building that happens to be the gateway to hell. Rosemary and her baby never had it this good. Full of great shocks including an ending worthy of Tod Browning's Freaks.
