The Scarlet Pimpernel (1934)

"They seek him here, they seek him there, those Frenchies seek him everywhere..." He's the cunning English spy code-named Pimpernel: master of disguises, savior to guillotine-bound aristocrats during the French Revolution, and most likely to be found in London making as big an ass of himself as credulity will allow. No one (not even his wife) would ever suspect the idiotic Sir Percy Blakeney of being the leader of an underground network of anti-Republic rebels, and it's still a joy to watch Leslie Howard, in the title role, successfully negotiating the ruse under the disdainful noses of his enemies. Without the unexpected element of farce the whole thing would be just another dated exercise in derring-do and low adventure, but the Pimpernel's foppish alter ego makes him one of the more unique (and hilarious) heroes ever to grace the silver screen. The poetry is, by the way, Sir Percy's own: "Is he in heaven, or is he in hell, that damned elusive Pimpernel?" ("It has a certain something..." he tells a giggling audience of landed gentry, "which gives it a certain...something.")
