During the mid to late 1940s, Walt Disney Productions had suffered financially after losing connections to the European film markets due to the outbreak of World War II. During this time, the studio endured box office bombs such as "Pinocchio" (1940), "Fantasia" (1940), and "Bambi" (1942), all of which would later become more successful with several re-releases in theaters and on home video. Due to this, the studio was over $4 million in debt and was on the verge of bankruptcy. Walt Disney and his animators returned to feature film production in 1948 after producing a string of package films with the idea of adapting Charles Perrault's "Cendrillon" into an animated film. After two years in production, "Cinderella" was released by RKO Radio Pictures on February 15, 1950. It became the greatest critical and commercial hit for the Disney studio since the first full-length animated film "Snow White and the Seven Dwarfs" (1937) and helped reverse the studio's fortunes. It received three Academy Award nominations, including Best Music, Original Song for "Bibbidi-Bobbidi-Boo".
