The spy who came in from the cold trailer

Hands down one of the best spy films ever made.
The Spy Who Came in from the Cold is a 1965 British Cold War spy film directed by Martin Ritt and starring Richard Burton, Claire Bloom, and Oskar Werner.
Based on the 1963 novel of the same name by John le Carré, the film is about a British agent who is sent to East Germany in order to sow disinformation about a powerful East German intelligence officer. With the aid of his unwitting English girlfriend, an idealistic communist, he allows himself to be recruited by the communists, but soon his charade unravels and he admits to being a British agent-a revelation that achieves the ultimate objective of the mission.
