The Haunting, based on Shirley Jackson’s spooky novel The Haunting of Hill House. I taught it once in grade 10 in my first year of teaching (on the curriculum then)–1972. Kids loved it.
The 1963 movie is faithful to the original. Excellent direction by Robert Wise, very atmospheric, strong cinematography, well-acted by Julie Harris and Claire Bloom. Highly recommended and still startles viewers today.
