There have been some outstanding movies about underground forces in Europe during WWII. There have been some excellent movies about espionage during WWII. And, there have been a number of very good movies that combine espionage and underground efforts. "Operation Secret" is far and away the very best of the latter, with a lot of intrigue and mystery tossed in. The film combines spy efforts with underground operations, and then adds some combat scenes and aerial bombing footage along with the mystery and intrigue. It involves a court inquiry after the war, and a story told in flashbacks from various characters.
Just as with "Where Eagles Dare," this film story is fictitious, but is about real subjects of the war. In the former, it was the efforts to knock out Norwegian plants before the Nazis could use them to produce heavy water for use in German nuclear arms plans. In "Operation Secret," the real subjects were Germany's V-2 rockets and jet aircraft.
This film excels in a number of areas. The plot and script are first- rate, and the acting is first-rate by the whole cast. The direction is excellent, as are the cinematography and the scenes. This may be one of Cornel Wilde's best performances, and Karl Malden gives a first-rate performance. To top it all off, the movie has some actual German footage of the V-2 rocket firings, and the actual footage of the earliest German jet aircraft tests. I recall seeing such tests only once before; so this is very rare among WWII movies.
I'm surprised that so few have seen this movie by this late date. I don't recall ever having seen it before, but I've added it to my film library. Now that it's on DVD, more folks should want to buy it. I think it's a "must" for any serious war film library. If you're not a collector, watch for its showing on TV. I highly recommend this excellent, interesting, intriguing and entertaining film. For a bit of trivia, in an early scene of a flight from New York to Paris, presumably around the time the film was made, 1952, the pilot announces over the plane's PA system that the flight will take "about 13 hours." That was the speed of the four-engine prop planes before the advent of commercial jet service.
