The Conversation is a tour de force, but it’s a quiet tour de force. In fact, it is just about impossible to imagine a movie like this being made today.
In Dostoeyevsky’s Notes From Underground the self-loathing narrator proposes that every man has secrets he will only reveal to friends and secrets he must keep to himself. And then there are the things he is afraid to admit even to himself, and the more decent the man, the more things he will find himself unable to confront.
In Francis Ford Coppola’s The Conversation Harry Caul (Gene Hackman) is a man less concerned with the answers to uneasy questions than the questions themselves. He is a well-regarded surveillance specialist; a self-employed spy who builds his own equipment and attracts high profile clients who will pay top dollar for his services. As he explains to his enthusiastic assistant (the always-excellent John Cazale), he is uninterested in the personal lives of his clients or what their motivations might be—he just wants to get the job done as only he can do it.
Caul, who claims not to care about the inner feelings of others, goes to great lengths to keep anyone from gleaning his personal thoughts. And from his old-fashioned eyeglasses, coat and tie attire or the see-through slicker he wears rain or shine, he projects the look of a professor or librarian more than efficient sleuth. This is entirely by design: by making himself as ordinary as possible, Caul believes he can keep others from intruding on his personal space—which we quickly understand is, for him, sacred. As such, he is a human coil of simmering tension, all nervous energy and restraint. He is a quiet man with an urgent dialogue endlessly unspooling in his mind. Or, he has several urgent dialogues simultaneously distracting him. Or, he is ceaselessly trying to suppress these urgent, distracting dialogues. That he is unsuccessful is obvious: his discomfort around others reveals the obsessions and idealizations simmering deeply beneath his austere façade.
