Billy Elliot: The Musical is a coming-of-age stage musical based on the 2000 film of the same name. The music is by Elton John, and the book and lyrics are by Lee Hall, who wrote the film's screenplay. The plot revolves around Billy, a motherless British boy who begins taking ballet lessons. The story of his personal struggle and fulfillment are balanced against a counter-story of family and community strife caused by the 1984–85 UK miners' strike in County Durham, in North East England. Hall's screenplay was inspired in part by A. J. Cronin's 1935 novel about a miners' strike, The Stars Look Down, to which the musical's opening song pays homage.
