Surveillance expert Harry Caul (played by Gene Hackman) is hired to tail a young couple, whom he records as they walk through the crowded Union Square in San Francisco. While listening to the recordings, he begins to suspect that the conversation he captured reveals a mysterious conspiracy.
Harry is considered an expert in his field. However, he is obsessively afraid of being eavesdropped on, which is why he keeps to himself, separating his professional life from his personal life. He is so hypersensitive about this that he defends his privacy by any means necessary.
Presented in the style of a thriller The Conversation raises questions about power, moral responsibility, and the consequences of advancing technology. It was made two years after The Godfather. The director used to say that he made the film about Vito Corleone solely to raise the funds needed to make the film about Harry Caul.
The financial and artistic success of the story about the mafia family allowed Coppola to realize his dream project. The Conversation is a film that, despite its universal and timeless message, fits into the atmosphere prevailing in the United States at the time, caused by the Watergate scandal.
With this film, Coppola confirmed his status as one of the most interesting filmmakers of the 1970s, combining the characteristics of American and European cinema.
For this film, he received the first Palme d’Or of his career at the Cannes International Film Festival (he would receive his second five years later for Apocalypse Now). He is one of nine directors to have twice received Cannes’ highest honor.
