The Husband and The Younger Son went on to bed last night, but The Daughter and I were up for another movie. I showed her The Haunting, which she had never seen, and afterwards we talked about whether or not we thought the house was actually haunted. I watched this movie a couple of years ago. The Haunting is a 1963 horror film directed by Robert Wise and starring Julie Harris, Claire Bloom, Lois Maxwell, Fay Compton and Valentine Dyall.

and the other sections are linked there, with part 2 here.
I'm partial to this film because it's plenty creepy without any gore. And yes, I think the house was really haunted.
