Director: Francis Ford Coppola
Stars: Gene Hackman, John Cazale, Allen Garfield

When people talk about Francis Ford Coppola's string of '70s classics, The Conversation inevitably receives the least shine. It's a smaller story, and a deeply personal and uncomfortable one, at that. No gangsters, no Vietnam, this modest picture only tackles the loss of security in the modern world.

Gene Hackman plays Harry Caul, a surveillance expert hired for a routine case—record a conversation—that seems to have led to a murder. This sends Caul, already a paranoid person, into a downward spiral of disquiet. Along the way, Coppola's explores heavy head-scratchers like responsibilty and privacy. Skip The Social Network and watch The Conversation.
