Torn curtain (1966)

Actors: Paul Newman, Julie Andrews
Dir: Sir Alfred Hitchcock

This is a political thriller by Sir Alfred (it can also be classified as a spy thriller). Though this film is not accepted as a Hitchcock hit, it was a minor box office success.

Michael Armstrong, an young nuclear scientist defects to East Germany. His young fiancée & assistant, Sarah Sherman trails him to East Berlin and confronts him. The twist and turns of the story reveal that Michael is actually no defector but is helping his country to unearth the East German and Soviet nuclear ambitions. Now Michael has to take with him the secret formula of the East German nuclear plan and his fiancée safely out of East Germany with the staci and the police chasing them.

The best scene in this movie is probably the murder of the East German staci by Michael and the farmers wife. Hitchcock rates this as one of his favorite sequences. In this sequence Sir Alfred actually demonstrates how difficult it is to kill a man. One of the best murder sequences I have ever seen.

Trivia: Sir Alfred makes an appearance very early in the film, sitting at the lobby of Hotel d'Angleterre with a blond baby on his lap
