Sleep No More) is a 1958 British suspense film directed by Michael Anderson and starring Richard Todd, Anne Baxter and Herbert Lom.

In her family's Spanish villa, Kimberly Prescott, a young South African heiress of a diamond company, is grieving after her father's recent suicide, when she is taken aback by the arrival of a man claiming to be her brother Ward, believed to have died in a car accident a few months ago.

[3] Dragon obtained finance from the Associated British Picture Corporation (ABPC) who had a releasing arrangement with Warner Bros.

"[9] The Monthly Film Bulletin wrote: "This virtuoso study in suspense only serves to show how remarkable is Hitchcock's gift of clothing his own often absurd fantasies in the incidentals of reality which give them "a peculiar credibility.

Michael Anderson's direction is often astonishingly clever in its tricky way; but the tour de force is too consistently maintained.

"[10] Bosley Crowther in his review for The New York Times considered the plot as overly complex and torturous but that the melodrama was "nothing amazing, and neither is this film.

[13] Leslie Halliwell opined: "Tricksy, lightly controlled suspense melodrama with a perfectly fair surprise sending.

"[14] The Radio Times Guide to Films gave the film 3/5 stars, writing: "Coming off the back of The Dam Busters (1955), 1984 (1956) and Around the World in 80 Days (1956), director Michael Anderson was destined for a disappointment, but it is to his credit that this ludicrously contrived thriller not only holds the attention, but also actually manages to induce a short intake of breath at the totally unexpected dénouement.

Anne Baxter gives her one of her best performances as a recuperating neurotic who is convinced long-lost brother Richard Todd is after her diamonds.

[17] Chase a Crooked Shadow was also an inspiration for the 1989 Hindi movie Khoj which was remade as Police Report (in Telugu, 1989) and Agni Sakshi (in Kannada, 1996).

[citation needed] The climax twist of the original was used as a reference point for the Kannada language Indian movie Yarivanu (1984).

[18] The original film also served as an inspiration for the French play Piège pour un homme seul (Trap for a Lonely Man) by Robert Thomas.

The play served as the source material for the TV movies Honeymoon with a Stranger (1969), One of My Wives Is Missing (1976), and Vanishing Act (1986).

[citation needed] Alfred Shaughnessy wrote a stage adaptation of the original film, Double Cut, first staged at the Thorndike Theatre, Leatherhead in 1984, with Simon Williams and Lucy Fleming in the leads, prior to touring the UK the following year with David Griffin and Tessa Wyatt.
