Lee is a wealthy businessman, John Preston, who arrives in the English town of Deanbridge. He matriculates himself in this sleepy area rather seamlessly as he buys a vast amount of real estate. Preston also has his eye on the bewitching Sally (Betta St. John) who is rather frigid with her former beau (Peter Grant), an amateur golf player. Sally is taken by Preston yet something is off about him - he snaps at her, snaps at the maitre-d of a local restaurant, and is always nervous, sweaty and anxious. Preston claims to have fought in World War II and hates France - the assumption being that he was a soldier during its German and Italian occupation. He intends to marry Sally yet is inclined to see a psychoanalyst (Alexander Knox) to deal with his recurring nightmare of a murder he may have committed under a different identity.
It does not take a genius to see where this is headed and thus suspense for this cumbersome drama is minimal. As an albeit brief psychological study of a man slowly losing his marbles, "Alias John Preston" has some tantalizing moments thanks to Christopher Lee's towering performance - he seems too big for this TV-style play yet is sometimes terrifying to watch. Alexander Knox is dead-on as the analyst who sees a lot more than he lets on. The film does drag a bit and most of it is as visually flat as a desert, yielding little surprise or imagination with its predictable story structure. For Christopher Lee completists, well worth checking it out at least once. Drink plenty of caffeine.
