A gothic Freudian nightmare from German maestro Fritz Lang, Secret Beyond the Door was adapted by his frequent collaborator Silvia Richards from a story by Rufus King. A sinister ‘40s twist on the French Bluebeard tale, the film is often considered a minor work in the great Lang’s oeuvre (far behind the almighty The Big Heat in my book), though even a lesser Lang film is better than the worst of most other filmmakers.
