Great Catherine is a 1968 British comedy film directed by Gordon Flemyng, based on a 1913 one act play by George Bernard Shaw, and starring Peter O'Toole, Zero Mostel, Jeanne Moreau and Jack Hawkins. Like the play, it is loosely based on the story of Sir Charles Hanbury Williams and his time spent as an envoy at the Russian court. It was shot at Shepperton Studios near London with sets designed by the art directors John Bryan and William Hutchinson. The score was composed by Dimitri Tiomkin.
