Not a very good film, to be honest... For your pleasure it is a propaganda film, if you enjoy that or double standard. Due to its origin, it is full of "patriotic" speeches disguised as dialogues, exaltation of the American notion of democracy, dark portraits of Soviets' Western allies, warnings of the "Red Menace" that sound insolent when you see how light-heartedly the H-bombing of Japan is assumed, and so on... William Wellman directs all the tension-filled action with his usual skill, and actors are rather restrained in their Soviet portraits, but in the end not even the self-righteousness of the project can hide its true political agenda.

The embellished story of Soviet defector Igor Gouzenko is told here in the documentary style that 20th Century Fox popularized in the post World War II period with such other films as The House On 92nd Street, The Street With No Name and 13 Rue Madeleine. Gouzenko is played here in tightlipped fashion for an uptight man by Dana Andrews with Mrs. Gouzenko played by frequent Andrews co-star Gene Tierney.Gouzenko was a security code clerk at the Soviet Embassy in Ottawa and was an important conduit for top secret information both in and out of official diplomatic channels. During the Cold War it was a standard practice for the Soviets to use their embassies as places of espionage as well as diplomacy as did we. But this started during World War II when both sides were ostensibly allies.Canada had its own role in World War II as an ally, an important supplier of troops and even more important guardian of the North Atlantic sea lanes for supplies. Their scientists worked on the Manhattan Project and the development of a super weapon certainly piqued Soviet interest. Just what were allies America and the United Kingdom working on?When we meet Gouzenko he's a pretty firm true believer in the evangelizing mission of the Soviet state. But what was presented satirically in films like Ninotchka and Comrade X is done seriously here. The material prosperity of the west is something Andrews pretends not to notice, but Tierney isn't quite as self controlled. The friendliness of neighbor Edna Best to Tierney and her infant son proves to be invaluable in the end. No wonder the Soviets tell Andrews to stand aloof from the ordinary Canadians. Random acts of kindness can sometimes really pay off.A good cast of villainous types play various Soviet embassy and intelligence officials. Two should be singled out, a female seductress played by June Havoc who tests Andrews discretion and loyalty and comes up short. And Eduard Franz who plays another embassy official who becomes disillusioned with Communism and isn't so discreet about it.For a Cold War era anti-Communist film, The Iron Curtain holds up well over 60 years later. How convenient of Winston Churchill to provide a title for this film with a famous speech in 1948.

The defection of Igor Gouzenko from the Soviet Embassy in Ottawa, Canada, in 1946, was one of the most electrifying events of the Cold War. The documents and information which he brought with him, gained from his work as a top-secret cipher clerk, resulted in the destruction of the main Soviet spy ring in Canada, which included a Member of Parliament and a nuclear scientist who was working on the atomic bomb. This film, with all the locations shot in Ottawa, and its details drawn from the official reports of a Royal Commission, is a fascinating depiction of the true story of Gouzenko from the moment of his arrival in Canada, his first time outside the Soviet Union, till his defection with his wife and child. William Wellmann directed the film in a low-key style, with some documentary linking narration from time to time. Dana Andrews was never so subdued and soft-spoken as Gouzenko in this film, and Gene Tierney is remarkably self-effacing as the devoted wife and mother of an infant. She has no particularly interesting scenes. The really powerful performances in this film are by Berry Kroeger, in his first film appearance, as an insidious, swaggering and menacing mastermind of a Soviet espionage ring, and Eduard Franz as a Soviet major who 'just cannot take it any more' and turns into a drunk. The film is tense and gripping, and follows closely the real life events of this notorious story. June Havoc is effective in a minor role as the resident Soviet honeypot who tests the new staff with alcohol and seduction to see if they are indiscreet. The world inside the Soviet Embassy is convincingly and eerily depicted, a demi-monde and a half-life of people serving Stalin and the Party like grim automatons with dark faces and all humanity stripped out of them. This film gives a nice lesson in the realities of sordid power, and the hollowness of institutionalised betrayal. There are none so low as those who slither.

Excellent film dealing with Soviet spies operating in Canada during World War 11 and afterward.The spying was done out of the Soviet embassy in Canada. There were plenty of non-Canadians involved in the spy ring as well.This film was a true story. Dana Andrews gives a subdued performance as a Soviet decoder who comes to appreciate democracy. He is soon joined in Canada by his wife who is played by Gene Tierney. She brings a simplicity to the role as the Soviet wife who also comes to respect a democratic way of life.There is an excellent performance by Eduard Franz, who plays an disenchanted alcoholic Soviet official, whose disdain for Soviet life will lead him back to the Soviet Union.The film is exciting since it shows how no one wanted to listen to Andrews unraveling of the spy ring.
