As my Father, Antony Darnborough produced this film and my uncle Muir Mathieson conducted the music, I might be slightly biased although I still feel that biological warfare was virtually unknown to the general public at the time and therefore this film was useful on many levels.Perhaps it can in some way highlight the efforts made by the hundreds of brave and talented civilians during the cold war, many of course had little or no idea what they were letting themselves in for and no training in interogation techniques.Classic line: "A few moths ago some people were shot in the woods - accidentally. Tourists"James Darnborough

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.

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.

Nicole Kidman was following an honourable tradition when she played a gorgeous neuro-surgeon in Days of Thunder for Highly Dangerous casts beautiful Margaret Lockwood as an entomologist. On this evidence the main job qualification seems to be that you don't find insects repulsive. What next, JayLo as a nuclear physicist?Despite being written by the estimable Eric Ambler, the screenplay for Highly Dangerous seems to me to be somewhat misjudged. The `humorous' elements, while never being remotely funny, serve to drain the excitement away from the dramatic sequences. I think the film would have worked much better as a straight thriller without all the nonsense of Margaret imagining she is a character in a radio serial after she's been given a `truth drug'Highly Dangerous has many elements typical of a Cold War drama of its time, the implacable police chief (a typecast Marius Goring), the brutal armed forces, the dissident priest who shelters the fugitives etc. Interesting that the war in this case is biological.Apart from the interest this film will have for the fans of Margaret Lockwood, a big British star of the years around World War II, Highly Dangerous is at best a fair time-passer.
