Related by Naxos about the silent film themes incorporated in the Music for Great Films of the Silent Era (1) CD's section The Gemini Concerto: "The classic film composer, Erich Wolfgang Korngold, based his popular violin concerto on themes he had written for four films: Another Dawn (1937), Juarez (1939), Anthony Adverse (1936) and The Prince and the Pauper (1937). William Perry, in writing his Gemini Concerto, has adopted the same approach and has drawn on thematic material from seven of his popular silent film scores.
"After presenting the travel music theme in the first movement and using it thereafter to introduce each subsequent movement, Perry uses a theme from Little Annie Rooney (1925), starring Mary Pickford for the Dublin movement and music from The Last Laugh (1924) starring Emil Jannings for Berlin. Tempest (1928), a John Barrymore film set in the closing days of Czarist Russia provides the love music for Moscow, and the waltz theme from A Kiss for Cinderella (1925) with Betty Bronson carries us to Vienna. The final movement, set in New York, draws on three silent scores: Show People (1928) with Marion Davies and William Haines, the Gloria Swanson comedy Fine Manners (1926), and the King Vidor masterpiece, The Crowd (1928)."
