A governess comes to take charge of two children in a large country house and comes to believe that they are channelling the spirits of two previous inhabitants, now deceased. Or is it all the product of her feverish imagination? The power here is that we're never really sure and thanks to Kerr's beautifully nuanced performance, barely holding it together, and Clayton's careful pacing and staging, it creates a real sense of unease, capped off by a couple of truly hair-raising moments. From the Less is More school of scary movies, probably the real star here is cinematographer Freddie Francis and his exemplary use of the Cinemascope widescreen.

From the amazing opening credits (the usual 20th Century fanfare is replaced by a child's lament and black screens) to the stunning end this is a classic in every sense. Much is owed to the razor sharp and often ambiguously unsettling dialogue written by Truman Capote, the stunning black and white photography and the outstanding acting from Deborah Kerr as well as the two young children. Yes, there are some Hammer Horror cliches like the open windows, rolling thunders, hysterical screaming and supposedly scary ghosts but the overall result is a hugely satisfying and positively memorable film.

Make sure you don't miss out on the extras, especially the 20min introduction that should be watched after seeing the film, though, as it contains a number of spoilers. However, it does give great insights without having to sit through the feature length commentary which I assume will provide further insights when I get around watching this next time.

This classic British spinechiller from the early 60s is, to my mind, probably the best ghost film ever made. Even watching it today, almost 50 years later it is a film that once seen will stay with you. Deborah Kerr is excellent as the repressed governess who discovers a terrible secret haunting the two children in her care. A sense of dread and menace pervades the film, much of it created by the superb black and white photography. No blood, no gore, just sinister events in a Victorian mansion. If you haven't seen it, try not to watch it alone, as you will be well and truly spooked. This is a truly scary film that belongs in the collection of all fans of the supernatural.
