Vernon and Irene Castle
In 1939, her life with Vernon was turned into a movie, The Story of Vernon and Irene Castle, produced by RKO and starring Fred Astaire and Ginger Rogers. Irene served as a technical advisor on the movie, but clashed with Rogers, who refused to short bob or darken her hair. Irene also objected to white actor Walter Brennan playing their servant: "Walter was BLACK".
