If you've never seen the 1965 film adaptation of John Le Carre's bestseller "The Spy Who Came in from the Cold", don't hesitate another minute. One of the great thrillers of the 1960s, directed by Martin Ritt with a complex screenplay by Paul Dehn and Guy Tosper that will have you riveted and guessing throughout. There's also a superb cast headed by Richard Burton in a glorious, Oscar-nominated performance as the dour, disillusioned secret agent.(Don'[t be discouraged by the hokey narration on this American trailer!)
