The Human Factor

This tense drama was the final film from director Otto Preminger (Laura, Anatomy of a Murder), with a star-studded cast and a screenplay by Tom Stoppard (Shakespeare in Love) adapted from Graham Greene's spy novel. At the offices of the British Secret Service, mild-mannered desk agent Maurice Castle (Nicol Williamson) is faced with a moral dilemma when he watches his office mate (Derek Jacobi) brought down for counterespionage. All the while, it is Castle who has been the one secretly leaking information to the Soviets, returning a favor to an old Communist friend in South Africa who helped Castle's wife (Iman) escape to England. When a South African official (Joop Doderer) pays a visit to work with the Brits on a new project, Castle's secrets begin to unravel and his life is changed forever.
