An effective and explicitly propagandistic wartime docudrama, co-directed by the ever-quirky Michael Powell, and clearly aimed at a hometown audience seeking reassurance during the ongoing German Blitz. Merle Oberon and Ralph Richardson star as a British couple doing their bit to beat back the Hun, but in truth the acting parts are the least noteworthy aspect of this feature-length film, which is structured more like a newsreel than a drama. The opening sequences, which feature a clever montage that juxtoposes the wholesome, modern look of freedom-loving England with the sinister, humourless world of the Nazis, has some great footage and several interesting aspects. The apparent faith in modernity (as extolled in the newly-built high-rise tenements and lengthy footage of wartime industrial production) and the uniquely Powell-ian sense of humor which frames the narration are equally of note... The second half of the film involves a recreation of an early RAF bombing raid on the mainland, and a lengthy dramatization of how the Brits would fend off German bombers through a combination of ground artillery and plane-to-plane dogfights. The film was probably also meant to act as disinformation: we are shown an elaborate, James Bond-ish, secret control center which coordinates information phoned in by local "plane watchers," when in fact Britain had already developed a radar defense, which proved key to their success in controlling the airspace over the English Channel. Likewise, there is no mention of the controversial "lend-lease" arrangement, set up with the nominally-neutral United States, which had not yet joined the war. Finally, this pro-RAF film proved to be rather prophetic, as it was produced and released just before the airborne Battle of Britain, which was one of the pivotal fights of the War. A fascinating and somewhat quaint bit of wartime propaganda.
