"The Spy Who Came in from the Cold" (1965) plunges viewers into the grim realities of espionage during the Cold War. British agent Alec Leamas, haunted by his past and the constant threat of defection, chooses to remain in the field for "one more mission." This perilous undertaking, however, proves to be a descent into a morally ambiguous labyrinth, pushing Leamas to his absolute limits as he navigates betrayal, shifting loyalties, and the very real possibility of his final assignment. This stark and unflinching portrayal of a spy's disillusionment makes "The Spy Who Came in from the Cold" a quintessential Martin Ritt film.
