Well, I recall them showing the shadowy statues bit, but yeah, some of the cut-out parts came as a surprise to me when I watched it the other night!
Having seen it now as an adult, the thing I appeciated most about the movie was how Roddy MacDowall makes everything more nervy just by showing up. Also, his glasses.
It's not The Haunting I'm thinking of (which I've seen loads of times), it seemed more distinctly British. Perhaps it was one of those Hammer films? With young, fashionable people converging on a haunted castle or th
at sort of thing? The cone (not beehive, mind you, but cone) haired girl's hairstlyle was the thing that I recall most clearly. My sister said at the time that women would get insects and mice inside of those hairdo's back then, which is probably why it stuck in my mind.
