These sort of espionage stories are not favorites of mine unless done with a storyline that is not too convoluted, as is sometimes the case in these kind of spy thrillers. But if they're taut and suspenseful throughout, I can forgive too many complications. Fortunately, the cat-and-mouse game played here is understandable enough and crackles with suspense and tension.

MAN ON A STRING is a spy thriller based on the true-life adventures of a real counter-spy Boris Morros (dubbed Boris Mitrov here),played by ERNEST BORGNINE. While the plotting is far from simple, it's easy enough to enjoy the air of menace and danger that permeates the entire story without getting bogged down into the details of entrapment that always accompany these spy stories.

It moves at a brisk pace under the direction of Andre deToth (for awhile, he was a husband of Veronica Lake in the '40s),and all of it is filmed on locations in East and West Germany. KERWIN MATTHEWS is Borgnine's fellow spy assigned to guide him through the various activities, COLLEEN DEWHURST does well in her second film after a couple of TV roles, and GLENN CORBETT is excellent as a government agent.

It's rather talky for the first hour and then builds to a tense climax among the deserted buildings of East Germany when Mitrov's activities become known to the Russians, which leads to a shootout scene that caps the ending in a satisfying and suspenseful way.

Borgnine gives a solid performance and the film itself is well worth watching.

There's a narration that gives it an almost documentary approach, somewhat like another film produced by Louis De Rochemont, THE HOUSE ON 92nd STREET.

Summing up: Crisp, exciting spy thriller.

Based on the real life story of Boris Morros who was a musician instead of a film producer, Man on a String comes at the tale end of the Cold War espionage thrillers where there was absolutely no doubt as to who the good guys and bad guys were on the screen.

I can understand the reason for renaming the lead character that Ernest Borgnine plays Boris Mitrov and changing his occupation even, for dramatic purposes to give the character more scope. But for the life of me was anyone fooled when the agency he worked for was renamed the Central Bureau of Intelligence?

Borris Morros has his own page on IMDb and you can see the rather astonishing list of film credits he had, working on the scoring of a whole lot of films, some of them classics like Stagecoach. His own life gives a lie to the notion that there were no Communists in Hollywood. The blunderbuss approach taken by the House Un-American Activities Committee is another issue altogether.

The Mitrov character we see here isn't exactly stealing the atomic secrets, in fact he's not really doing any spying at all so to speak. As the Russian agent says, all they're doing with him is buying his good name to gain entrée into other places.

Our own CIA knows that and turns him into a double agent where he does perform useful work in identifying Soviet agents here. In real life it wasn't quite as dramatic as shown in Man on a String.

One thing that is of interest is that Man on a String, made as it was in 1960 in the wake of Nikita Khruschev's boast about how he would bury America. That is their attitude, that victory for them was inevitable because Marx said that's how history was flowing. It's interesting to watch this film now in the light of the fall of the Soviet Union. And it fell because it's economy couldn't keep spending militarily and provide its citizens with basic necessities.

Man on a String is a Cold War relic, but interesting viewing nonetheless.

Had no idea if I was going to enjoy this film from 1960, but I had a good idea that Ernest Borgniine, ( Boris Mitrov) would put his heart and soul into his role and he did just that through out the entire film. This was a true story concerning a man who was called Borris Morras, and in this picture was called Boris Mitrov a double agent between the United States and Russia during the Cold War Era. Boris Mitrov is a successful Hollywood producer who was born in Russia and got himself involved with Russian Spys who were willing to bring his father and brothers back from Russia to his home in Los Angeles. However, Boris Mitrov is being watched by our Government Agents and they decided to enlist Boris to become a double agent for the United States in order to be cleared of the charges for espionage against the U.S. There is plenty of suspense and this story takes many twists and turns.
