Xanadu is a 1980 American musical fantasy film written by Richard Christian Danus and Marc Reid Rubel, and directed by Robert Greenwald. The film stars Olivia Newton-John, Michael Beck and Gene Kelly in his final film role. It features music by Newton-John, Electric Light Orchestra, Cliff Richard, and the Tubes. The title is a reference to the nightclub in the film, which takes its name from Xanadu, the summer capital of Kublai Khan's Yuan Dynasty in China. This city appears in Kubla Khan by Samuel Taylor Coleridge, an 1816 poem that is quoted in the film.
