The Cool Mikado is a British musical film made in 1962, directed by Michael Winner, and produced by Harold Baim, with music arranged by Martin Slavin and John Barry. It starred Frankie Howerd, Lionel Blair and Stubby Kaye. The script was by Michael Winner, from an adaptation by Maurice Browning. Based on the Gilbert and Sullivan comic opera The Mikado, the plot is reset into contemporary Japan as a comic gangster story. The dialogue was largely rewritten, and several of the well known musical items omitted. The music that remains was re-orchestrated into styles popular in the early 1960s, including the twist, and the Cha-Cha-Cha.

Filmed entirely on a sound stage, stock footage was used to provide Japanese atmosphere between scenes. This footage may have been culled from one of the many travelogues for which Baim is best known. No attempt appears to have been made to disguise the stage-bound filming. The colourful sparsely dressed sets, not always tending towards realism, give the film a surreal quality.

This film was Frankie Howerd's first musical, and in turn led to his starring in A Funny Thing Happened on the Way to the Forum on stage and in several conventional Gilbert and Sullivan adaptations, including Sir Joseph Porter in H.M.S. Pinafore and the Learned Judge in Trial by Jury.

Adapted from "The Mikado" by William S. Gilbert and Arthur Sullivan (I), at the first opportunity after copyright expired, 50 years after Gilbert's death.
