"The Mikado" -- the crown jewel of Gilbert and Sullivan operettas -- blooms brightly as an on-screen comedy in this performance with actors from Britain's D'Oyly Carte opera company. Nanki-Poo (Kenny Baker), a minstrel who finds his way to the Japanese village of Titi-Pu, meets town executioner Ko-Ko (Martyn Green). But when Nanki-Poo discovers Ko-Ko must perform at least one killing per day, he realizes he may not live to see another day.
