Some 20 years before Ian Fleming started writing about these things, it's nice to know that the British Secret Service was on the job and apprehending spies and saboteurs even if they're a bit slow to catch on at times. With a little inside help from the air plant, some Teutonic looking gentleman have perfected a ray that immobilizes airships and brings them down real nice on the ocean. No trace of about four warships has been found at all or their crews. It's of concern to test pilot Laurence Olivier, to British agent Ralph Richardson, and to news reporter Valerie Hobson.Hobson and Richardson are brother and sister. As you can imagine his job involves secrecy and undercover work and Hobson's from the Lois Lane school of journalism. Family dinners must really be something in that family. She also falls for Olivier while she's undercover working as a waitress at a coffee shop near the plane factory.Q Planes must have been seen as wildly fantastic by the 1939 audience, but two generations who saw Sean Connery and Roger Moore engage in even wilder derring-do than is shown in this film, would regard Q Planes as all in a day's work. Olivier and Hobson are fine, but Richardson steals the film whenever he's on screen. Q Planes will never be ranked as in the top 10 of any of these players, but it's a nice breezy espionage comedy/drama made a lot better by some of the greatest thespian talent in the English speaking world of the last century.

The young Oliver and Richardson -- especially Richardson -- are obviously having a ball in this mix of spies, high adventure, and tongue in cheek comedy According to Michael Powell, the two stars tore up the script, and devised their own scenes, and the pleasure they have in sending up the material, and in each other's work, shines through. (In fact, once or twice, Oliver seems to be trying not to crack up at Richardson's antics.) Patrick Macnee says he based The Avengers' John Steed on Richardson's character in this film, and that, too, shows. Thrills, spills,secret rays, gags and eccentric British characters, and villains from a country suspiciously reminiscent of Germany, but not named in 1938.

When newly developed planes being disappearing during testing with no trace a police Inspector and a test pilot begin to look into the possibility of espionage within the company.Wartime dramas are very much of a standard affair – feel good affairs where we beat the Germans. This is very much one of those – the story is very flimsy and unlikely but it manages to have plenty to commend it. The story is carry by the comedy and the characters that make you overlook the sheer unlikely way in which the planes vanish. The story progresses to the inevitable shootout between the Brits and the Germans but on the way there's plenty to enjoy.The film is mainly saved by a wonderful performance by Ralph Richardson as the inspector – he is funny from the first scene and his character is wonderfully charming and forgetful. Olivier is also good, but it's not his best! The supporting cast of sassy women and foolish businessmen also add to the mix to make for an enjoyable romp.Overall this isn't a classic but the comedy and a superb Richardson makes this better than the sum of it's parts.

A 'Korda Collection' classic film and I shan't part with my videocassette - 'Tiger' comic script and stilted dialogue notwithstanding. Doesn't even matter that McVane appears to take off in a different airplane to that which is captured and seen in flight. Only trouble with Valerie Hobson is she retired too early.
