7. THE CONVERSATION (1974)

Francis Ford Coppola directed this taut look at how, sometimes, it’s Big Brother types that experience the worst paranoia. Released in between Coppola’s The Godfather and The Godfather Part II, The Conversation follows a surveillance expert (Gene Hackman) who begins to worry that the couple he’s been assigned to bug will be murdered once his job is done. Overcome by his good conscience, Hackman starts flaking on his assignment, which gives his employer (Harrison Ford) the script to flip and start wire-tapping Hackman. When Big Bro is on the loose, nobody is safe—not even the dirtbags who’d invade your privacy for a few bucks.
