In truth, there is barely enough story here to make a film.

Excellent characters with emotional depth. My wife, daughter and granddaughter all enjoyed it...and me, too! Very good movie! You won't be disappointed.

Excellent and certainly provocative... If nothing else, the film is a real conversation starter.

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

Colonel Alex Scotland did serve with the German Army between 1903 and 1907.However during the Second World War he was in charge of the London interrogation centre of Prisoners of war.He wrote about his experiences in The London Cage.So entertaining as this film is it is a fiction.In any event how valuable would such a source be when the Allies had Ultra and were reading the messages from Hitler's headquarters.

I didn't start out thinking I was going to like The Two-Headed Spy. I thought it was going to be another WW2 spy movie that would be too wordy and more boring than exciting. By the time the first half hour had passed, I was positively riveted! Jack Hawkins is a German general, and is very well-respected among his fellow Nazis. Then, he's seen entering an antiques shop and speaking to Donald Pleasance about a rare clock he's looking to buy. The conversation about a clock is merely a ruse until they know they're alone and unobserved—Jack Hawkins is really an undercover British agent! Previously, I'd only seen Jack Hawkins in a supporting role in Ben-Hur, but he carries off the leading role very well, commanding the screen and expressing every emotion with confidence. The Two-Headed Spy is a very riveting spy movie, with countless tension-filled scenes in which someone could—or does—get caught, discovered, and punished for being a spy. It really is an interesting, overlooked film from the 50s. Gia Scala, another of Jack's contacts, is beautiful and strong, rather like a prettier, more likable Ingrid Bergman. Had this film starred more well-known actors, it would probably be a classic. As it is, it's highly entertaining and fun—rent it for a thrilling evening with your sweetie-pie. The ladies won't be bored with this one, I guarantee it. And, if you're looking closely enough, you can see Michael Caine in one of his earliest movies. He's only on the screen for a couple of minutes, but when you hear the Nazi speaking with a Cockney accent, you can tell it's him!

The opening scene of "the two-Headed Spy" has a script that dedicates the film. It reads, "To those men of the Intelligence Service who worked in secrecy. Who struggled and died in darkness. To those lonely and courageous men who risked their lives daily in the enemy camp. This picture is dedicated. And, to one of those men, Colonel A. P. Scotland, O.B.E., British Intelligence Service, whose exploits over the past half century inspired this story. We wish to express our thanks."Indeed, the background of Alexander Scotland is very interesting. Here was an early implementer of interrogation methods, as well as a highly experienced spy. That's a story worth looking into. Scotland served as adviser for this film. While he had posed as lower ranking German officers and NCOs in World War I and at other times, he said he never was a high-ranking German official. Yet, when one notices some similarities in this film, it does raise a question. This film stars Jack Hawkins in a fictitious plot as just such a British spy. Gen. Alex Schotland was a British agent who served in the German Army of WW I. But, unlike most in the espionage business, after the war he didn't come out. He stayed in Germany, kept his military affiliation and identity, and when the Nazis began a rise to power, he jumped on the train. This is a very good and interesting look at how such high level direct espionage might have looked. One quickly comes to the conclusion that the best way to advance and get on the good graces inside the Nazi hierarchy was to agree with Hitler and promise that his every command could be carried out. Especially, if that went against the reasoned, experienced generals, regardless of how bad was Hitler's position. Anyway, that's how Schottland does it here. A distant romantic connection is provided by Gia Scala who plays Lili Geyr, a renowned German singer and entertainer of troops. The story has an interesting ending. Scala made a few very good films and had a promising career in movies and television. But, she suffered from depression and began drinking heavily. She underwent frequent psychiatric treatment. On April 30, 1972, she died from an overdose of alcohol and sleeping pills.

I have nothing much to add to the reviews already here, but that I loved the film. Stylish, beautifully paced, and remarkably suspenseful, it features an intriguingly controlled and flawlessly nuanced performance by Jack Hawkins, who makes you believe it possible that a British agent, hidden for twenty years, could exist undercover at the highest levels of the Third Reich. And as a sign of the 1958 that produced "The Two-Headed Spy," most revealing of the relationships between international film interests that the blacklisted Michael Wilson and Alfred Levitt were denied credit as scriptwriters in a British film because of its U.S. release by Columbia.However, for the record, I would like to correct a remark made by oxbridgeup from New Hampshire, who took issue with the use of tape recording in a scene, stating that it was not invented until 1947. Tape recording had actually been invented in Germany in the 1930s; it was used extensively in radio stations and by the Gestapo, most effectively as a tool to issue simultaneous statements by Hitler to units at all the various military fronts to give the Fuhrer the illusion of omnipresence. 1947 is the year the technology was introduced in the United States, and was patented by a group funded by Bing Crosby, who saw the potential in the format. An American audio engineer who, while assigned to the U.S. Army Signal Corps, had absconded with two of the pioneering German Magnetophon recorders (and numerous IG Farben magnetic tapes) at WWII's end, presented the technology to MGM and Crosby. Before this forming of Ampex, Farben had held the rights for magnetic tape (originally patented in the '20s as a long paper strip with an iron oxide coating) and AEG for recording/playing decks and their improvements -- most significantly, AC tape bias and stereophonic recording. Farben was, of course, dissolved in 1945 because of its cooperation with the Nazi regime (and notorious production of Xyklon-B), thus leaving its patents for the taking. How the AEG patents were voided is a mystery to me, but perhaps some knowledgeable reader might enlighten us.
