The Conversation (1974)

Gene Hackman plays Harry Caul, a surveillance expert obsessed with preserving his own privacy and dogged by a sense that with his latest assignment he is on the verge of repeating a past mistake. A fascinating look into the obscure subculture of professional eavesdroppers, The Conversation is also a penetrating psychological portrait, with a powerful performance by Hackman and a stunning-yet-logical plot twist at the end.

The cast includes: Gene Hackman, Teri Garr, Frederic Forrest, and Harrison Ford.

Directed by: Francis Ford Coppola.
