beautifully directed as the camera glides over dark shadows (of the mind).

The gothic Secret Beyond the Door (Lang, 1947) is a mesmerising, masterly film, again using the Freudian hook. A husband (Michael Redgrave in one of his rare Hollywood outings) is obsessed with rooms where murders have occurred. But what filthy thing lies beyond the door that’s always kept locked?

Some great extras and sparkling transfers totally justify the hefty price tag on this fine boxed set.
