Dreamy psychological noir (adapted from a novel by Winston Graham) which is obviously inspired by Alfred Hitchcock. And that includes the casting of a cool, elegant blonde in Arlene Dahl as a mysterious femme fatale who may be sizing up a stolid insurance man and old flame (Jack Hawkins) for the role of fall guy.
This is a hooky melodrama which grips all the way, so it scarcely matters that the labyrinthine plot rests heavily on coincidence. Dahl is a Hollywood star cast for the export market, but brings ambiguity, and looks great. She might feel reminiscent of Kim Novak in Vertigo, except this was out a year earlier!
Perhaps Hawkins isn't ideal in a romantic role, and he fluffs the sexy banter. But he is at least a believable insurance man... In Hollywood, the film noir cycle was coming to an end, but this deep, hazy, convoluted conundrum shows just how resilient are its motifs...
Launder and Gilliat load the dialogue with fatalistic poetry and pessimistic wisecracks, augmented by an ominous narration by Hawkins. And there's expressionist photography, including some eye-popping point-of-view shots and dream sequences. This isn't as auspicious as a '50s Hitchcock film, but still an effective, exciting UK alternative.
