Klute (1971)

The inaugural chapter of Pakula's paranoia trilogy exposes how surveillance penetrates intimate human relationships, scored by Michael Small's discordant telephone chimes. Jane Fonda delivers a tour de force as a Manhattan call girl stalked by a corporate executive whose dark compulsions are recorded on covert audio cassettes. The film documents how technological voyeurism turns private lives into leverage, exposing the predatory underbelly of corporate respectability.
