Element of Doubt (1996) – Christopher Morahan.

Gina McKee and Nigel Havers star in thrillingly above average 90s TV treat Element of Doubt, with notable character actor Michael Jayston being on splendidly chilling form! Morahan's tense, slickly fashioned psychodrama has an engaging text, steeled with sinisterly Patricia Highsmith'd, playfully nefarious Hitchcockian incident. I don't know if the entertaining What Lies Beneath-ish Element of Doubt is currently widely available for purchase, but it should be, since it ably provides lively distraction to avid thriller addicts! McKee and Havers have great chemistry as the increasingly adversarial married couple, with smoothly duplicitous rapscallion Havers being slippier than a Greek salad, and angsty McKee is distractingly beautiful, providing an exquisitely pale, enormously sympathetic, Clouzot-like heroine.
