Playboy flier Tyrone Power enlists in RAF at the start of WW2. In London he literally bumps into his ex-girlfriend, dancer Betty Grable, and tries to rekindle their romance, in this exciting wartime adventure written by studio chief Darryl Zanuck (under the name of Melville Crossman). Hollywood's first WW2 film is a very authentic account of the early days of Britain at war. Good use of actual aerial battle-scene footage. And Grable adds a touch of much-needed sex appeal in her scenes with Power. In the original story Power's character was killed in battle, but when the British War Office heard of this, they pleaded with Zanuck to change the ending as it would have a bad effect on the morale of UK citizens! Zanuck conceded, and Power wins Grable in the end. Oh well, that's Hollywood.
