Here are 4 classics from the 1960's, which unfortunately have faded into obscurity :
1) Black Sunday (1960) .... 9/10
Great gothic horror film. While being burned at the stake, a witch vows revenge on the descendants of her executioners. Hundreds of years later, she returns to keep her promise. It's better than that synopsis sounds.
2) Eyes Without a Face (1962) .... 9/10
This is a French language film, with English subtitles. A renowned plastic surgeon accidentally disfigures his beautiful daughter, in a reckless car accident. Overwhelmed with guilt, he attempts to repair the damage to his daughter by transplanting the face of his mistress, who is also one of his nurses. For it's time, it is surprisingly graphic and disturbing. Even by today's standards some of the scenes are pretty gross.
3) Carnival of Souls (1962) .... 10/10
A shy, young woman in a small Kansas town is the sole survivor of a drag racing accident. She is later haunted by an apparition. Makes great use of an organ musical score, and it's mood is effectively creepy. It has a low budget charm to it as well. Extremely well made.
4) Repulsion (1965) .... 10/10
Horror great Roman Polanski's first English movie is a classic. It's a psychological horror about a young woman who has developed an irrational fear of interacting with men which resulted from being sexually abused by her father as a child.
All 4 are available to rent on Amazon Prime Video.
