''Torn Curtain'' is a 1966 political {{thriller}}, directed by Creator/AlfredHitchcock and starring Creator/PaulNewman and Creator/JulieAndrews.

Michael Armstrong (Newman) is an esteemed American physicist and rocket scientist. He is supposed to attend a scientific conference in Copenhagen, but instead heads for East Berlin. Apparently defecting to East Germany. He is soon followed by Sarah Sherman (Andrews), his assistant and fiancée. She is very reluctant in doing so but remains loyal to him.

The defection is actually a ruse. Armstrong wants to meet Gustav Lindt (Ludwig Donath), the chief scientist in the East German military, to establish the extent of the Eastern Bloc's knowledge on anti-missile systems. He supposedly has a way to exit the country at will. Stasi, the East German state security service, has a very different view on the matter. Armstrong and Sherman are about to find out that entering East Germany was easy. Leaving East Germany is another matter entirely.

Hitchcock was not entirely happy with the casting of this film. He wanted Creator/CaryGrant as the male lead, with either Eva Marie Saint or Tippi Hedren as the leading lady. Grant turned him down. He was preoccupied with filming ''Film/WalkDontRun'' and intended to retire after that. Universal Pictures executives insisted on casting Newman and Andrews, in the belief that more famous (and also more current) stars would result in better box office results. Newman had starred in several hits the 1950s. Andrews was a younger actress who was mostly known for theatrical work prior to starring in ''Film/MaryPoppins''. After that film turned to a box office hit, she became one of the most famous actresses of the 1960s. Hitchcock and Newman had a difficult working relationship, Andrews felt borderline mistreated by Hitchcock due to the way he "neglected" her (as opposed to fetishizing her the way he usually did to his leading ladies), and the chemistry between the leads was rather poor. Nevertheless, it was a modest box office hit.

!!Troped Curtain:
* BavarianFireDrill: Michael shouts "Fire!" in a crowded theatre as a distraction to escape from the East German police.
* BreakHerHeartToSaveHer: Michael does this to Sarah (in a way) to keep his secrets from her at the beginning of the film.
* CoolOldLady: Countess Kuchinska, a little eccentric but [[spoiler: she sacrifices her own chance to get to America by helping the heroes get away.]]
* EurekaMoment: Lindt has one upon realizing [[spoiler: he's been giving up his secrets while learning nothing from Armstrong in return.]]
* FakeDefector: Michael Armstrong.
* GracefulLoser: When [[spoiler: Countess Kuchinska is unable to get away along with Michael and Sarah. She sadly notes her disappointment, but apparently doesn't blame the couple.]]
* HiddenInPlainSight: Professor Lindt's anti-missile equations are on a chalk board for any and all to see. Makes sense since he was working at a (supposedly) secure facility were only authorized personnel would be allowed inside.
* {{Jerkass}}: The Ballerina.
* MacGuffin: [[spoiler: The Soviet Union's anti-missile system equations.]]
* RasputinianDeath: Hermann Gromek, the first Stasi agent Armstrong attempts to kill, takes a good long while to go down, including spending most of the climactic fight with a butcher knife sticking out of his chest. Hitchcock's main goal with the film was to show how hard it could really be to kill someone.
* RealityEnsues: It turns out that killing someone isn't as easy as it looks in the movies. This was a deliberate choice by Hitchcock because a number of spy thrillers at the time made killing look effortless.
