In the 1960s, Gwen Verdon read the play and asked her husband, Bob Fosse, about the possibility of creating a musical adaptation. Fosse approached playwright Watkins numerous times to buy the rights, but she repeatedly declined. However, upon her death in 1969, her estate sold the rights to producer Richard Fryer, Verdon, and Fosse. John Kander and Fred Ebb began work on the musical score, modeling each number on a traditional vaudeville number or a vaudeville performer. This format made explicit the show's comparison between "justice", "show-business", and contemporary society. Ebb and Fosse penned the book of the musical, and Fosse also directed and choreographed. The musical version in turn was adapted as the 2002 film Chicago, starring Renee Zellweger, Richard Gere and Catherine Zeta-Jones; this adaptation won the Academy Award for Best Picture at the 75th Academy Awards.
