Margaret Lockwood is Frances Gray, a scientist who takes on a government assignment that is "Highly Dangerous" in this 1950 film also starring Dane Clark, Wilfred Hyde-White and Marius Goring. Frances Gray works with bugs, so the government asks her to go to a country of opposing ideology and get a sample of bugs being used by them, possibly for germ warfare. At first, she says no, and then relents and travels to this unnamed country posing as a tour director checking out possible tour locations. Her cover is blown immediately by the chief of police (a heavily disguised Goring) who is on the train with her, and shortly afterward, her contact is killed, and she is arrested, drugged and questioned. The head of the British consulate, tipped off by a newspaper reporter she met previously (Clark) secures her release.The film starts out as a drama, but the mood lightens once she's out of prison. Under the influence of the drug she's been given, she plots a way to get into the lab based not on reality but on the antics of a radio spy on a program her nephew likes. The reporter knows it won't work, but when the first part of it actually does, he goes along.Margaret Lockwood went through several phases during her career - this was her mid period, after the ingénue of "The Lady Vanishes" and before the older woman in "Cast a Dark Shadow." She does a good job and looks very attractive. The stronger role was Clark's - he was being groomed as another John Garfield but never quite got there - he's very good, handling both the dramatic and the comic aspects well. Goring is a far cry from Victoria's husband in "The Red Shoes" -this seems an odd role for him, but he's excellent.An odd film but, if taken for what it is, a good one.

Fairly daft but won't hurt you. Dane Clark is amiable, a more than competent actor and has an understated way that works with the rather poor chances of comedy he's handed. Margaret Lockwood looks good and don't knock her as an actress either, this isn't Macbeth. And remember this was 1950, don't compare it with present day overblown and infinitely less believable efforts. As another reviewer said "See it once.", I've seen it twice - and lived. I notice a minimum of 10 lines is required There isn't much more to say coupled with other reviewers opinions. I wouldn't make a special effort to see this film but there have been a lot worse. Ten lines? Good. Goodbye.

Although I agree with most of the criticisms in the negative review already posted - I have just watched this movie on TV over lunch and really quite enjoyed it, which is why I came to this site to be reminded of the cast. I was surprised to see Anthony Newly's name - didn't recognise him. Margaret Lockwood looks much prettier than in many of her other films - her mouth is less prominent and her hair better groomed. Although I don't think it is worth seeing more than once - I do think it is pleasurable enough to watch once. Plenty of films are made of which that is not so. So if you haven't seen it - you won't hate it. It's just not absolutely terrific.

Margaret Lockwood is in it- "Hoorah!" And it's about a biological scientist who is sent behind the Iron Curtain as a spy, and she gets captured and, under hypnotism fulfilled her mission. "So Rex Harrison is in it, and the basic plot should be be as logical and driving the action along as (for example)'Night Train to Munich'?" Er... no on both counts. "Why?" Well, Rex wasn't in it. American B-movie actor Dane Clark plays Margaret's buddy. He is a very boring Journalist. And the plot is confused and rambles. And the plot is disjointed and includes a bizarre truth drug/BBC radio serial sub-sub plot. So subplot, I had no idea what was the point of it. "Ah! Anything else?" Yes, who is the child Margaret talks to at the start of the film? Is she married,if so, why does she kiss Dane at the film end? To be blunt, the film should have been re-scripted and re-written and it would have been as good as any film from that period. Better casting and a positive decision by the director and producer whether they were creating a serious spy movie or Light Thriller would have tightened the action,dialogue and direction. I like B&W British Film, but this is one I have seen and will not revisit.
