Top Hat is a 1935 screwball comedy musical film in which Fred Astaire plays an American dancer named Jerry Travers, who comes to London to star in a show produced by Horace Hardwick (Edward Everett Horton). He meets and attempts to impress Dale Tremont (Ginger Rogers) to win her affection. The film also features Eric Blore as Hardwick's valet Bates, Erik Rhodes as Alberto Beddini, a fashion designer and rival for Dale's affections, and Helen Broderick as Hardwick's long-suffering wife Madge. The film was written by Allan Scott and Dwight Taylor. It was directed by Mark Sandrich. The songs were written by Irving Berlin. “Top Hat, White Tie and Tails” and “Cheek to Cheek” have become American song classics.
