William Schwenck Gilbert is the librettist, writing the words. Arthur Sullivan is the composer, writing the music. Gilbert is the very model of a 19th-century British gentleman, an overly proper married man certain that he knows best. For nearly a decade, Gilbert and Sullivan's collaborations have delighted the English people. Their popular comic operas have recouped handsomely for the successful Savoy Theatre... But, in 1884, as a London heat wave cuts into the theater trade, their latest work, "Princess Ida," receives lukewarm press. Sullivan rejects Gilbert's next idea as "topsy-turvy" and unbelievable, and although Gilbert tries to accommodate him, they cannot agree. Mired at a creative impasse, Gilbert and Sullivan can barely converse. Then, Gilbert's wife, Lucy "Kitty" Gilbert, drags him along to a Japanese exhibition--exposure to the very different culture begins inspiration to embark on the production of "The Mikado."
