The prolific, ever-provocative Joseph Losey, blacklisted from Hollywood and living in England, delivered a coolly modernist shock to the system of that nation’s cinema with this mesmerizing dissection of class, sexuality, and power. A dissolute scion of the upper crust (James Fox) finds the seemingly perfect manservant (a diabolical Dirk Bogarde, during his transition from matinee idol to art-house icon) to oversee his new London town house. But not all is as it seems, as traditional social hierarchies are gradually, disturbingly destabilized. Lustrously disorienting cinematography and a masterful script by playwright Harold Pinter merge in The Servant, a tour de force of mounting psychosexual menace.
