Dark Obsession on AllMovie

Dark Obsession is a slow, English-made, psychological thriller dealing with erotic obsession, guilt and betrayal. Sir Hugo Buckton (Gabriel Byrne), an aristocrat strapped for money, is married to beautiful, sensual and successful Virginia (Amanda Donohoe). His alcoholism and his envy of her lead to his obsessive jealousy and belief in her lack of fidelity. During one drunken evening while out driving with friends, Hugo hits and kills a pedestrian who resembles Virginia. When Hugo begins to receive vague blackmail letters, he suspects one of his friends, and the group begins to plot a murder. Dark Obsession has all the ingredients of a first-rate thriller but fails despite its excellent cast to generate any excitement. The pace of the film is languid, the motivations of the characters are unclear, and after the accidental death, nothing much really happens. Dark Obsession, originally released as Diamond Skulls, despite the best efforts of its cast, is a thriller that fails to thrill.
