The semidocumentary war film The Lion Has Wings states its case in broad strokes, juxtaposing images of rampaging German-dictator Adolf Hitler and appeasing British prime minister Neville Chamberlain with stock shots of bleating sheep. The film then depicts Great Britain as a great lion, willing and able to sprout "wings" in the form of waves of planes to hurl back the Luftwaffe. The dramatic portion of the film, lensed in ten days to assure timeliness (and, incidentally, a low budget) features an all-star British cast reflecting their native country's many reactions to the inevitability of war. All the on-camera talent involved (including Merle Oberon, Ralph Richardson and June Duprez) donated their salaries to the war effort. Produced by Alexander Korda (who also directed a few bridging sequences, sans credit), The Lion Has Wings was distributed in the US by United Artists.
