In 2006, Disney announced its return to hand-drawn animation with The Princess and the Frog, then titled: The Frog Princess. This would be the first film in which Disney would showcase an African American Princess in its animated film canon. The Wonderful World of Disney produced a TV version of Rodgers & Hammerstein's Cinderella on November 2, 1997, starring the pop star Brandy in the title role. However, Disney had yet to include a black heroine in its popular Disney Princess line of movies and merchandising. Princess and the Frog had its wide release in the United States on December 11, 2009, but the movie was not without controversy during its development.
