It's all about the journey, right?
Spy Who Came In From The Cold (1965, Martin Ritt) Excellent Cold War espionage yarn based on (recently deceased) John le Carré's novel of the same name. A talking heads flick, for the most part, the film (anyway) is an intriguing character study that is served very well by Richard Burton. The Cold War atmosphere is wonderfully conveyed. Really brilliant camerawork by
Oswald Morris. Makes the movie (imo).
