Michael Powell's genius is exploding in wondrous innovations and marvels of imagination already in this early film about Wales. The introduction sets the mood, when a Welsh woman as the station master comes to greet a train with its passenger, the new lighthouse guard, in a fantastic local rural costume like a witch and speaking no word of English but only Welsh,. The hysterical intrigues and events are very much reminding of Hitchcock's "Number Seventeen" three years earlier, the same kind of mix of terror and madness, eccentrics and cluster of colliding events, getting grimmer all the time, but the local atmosphere is the dominating charm. It's about wreckers using the local people's readiness for superstition to operate their wicked business, Hitchcock was to use the same theme in "Jamaica Inn" four years later, and both films are equally successful and irresistibly charming and exciting. There is no Charles Laughton and Maureen O'Hara here, but instead you have Gordon Harker who is the right man for the job, although he gets too much to handle. The story is terrific, and Michael Powell was to use much of the same vein in his later masterpiece "I Know Where I Am Going" in Scotland ten years later.
