London psychiatrist Clive Riordan, royally fed up with the repeated affairs of his wife Storm, plots a seemingly 'perfect' revenge against her latest lover, American Bill Kronin. Catching them in the act, he marches Bill off at gunpoint; and from the viewpoint of Storm and the rest of the world, Bill simply vanishes. But there's far more to the meticulously worked out plot than Clive's victims suspect, with the end slowly preparing in his private laboratory. Enter a mild-mannered Scotland Yard man, who seemingly has no clue beyond a missing dog... Written by Rod Crawford <puffinus@u.washington.edu>

Brilliantly conceived and realised film noir
11 August 2001 | by (London, UK) – See all my reviews

Robert Newton gives a restrained and powerful performance as a cuckolded doctor exacting revenge on his high-spirited wife by abducting her young American lover, then keeping her guessing as to where he is, and whether he is still alive. Sally Gray is nothing short of brilliant as the wife. And, Naughton Wayne is magnificent as the dogged police inspector. Obsession combines brilliantly chiseled characterisations with an extremely intelligent and literate screenplay. Keep it on tape, because no one gets all the nuances the first time he or she watches it, but it's all put together so brilliantly the repeat viewings become a glorious pleasure.
