Sound film
The primary steps in the commercialization of sound cinema were taken in the mid- to late 1920s. At first, the sound films which included synchronized dialogue, known as "talking pictures", or "talkies", were exclusively shorts. The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was "The Jazz Singer", released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology. Sound-on-film, however, would soon become the standard for talking pictures.
Ladislas Starevich
Often mentioned as being among his best work, "The Tale of the Fox" (, ) was also his first animated feature. It was entirely made by him and his daughter, Irene. Production took place in Fontenay-sous-Bois from 1929–1930. When the film was ready, the producer, Louis Nalpas, decided to add sound by disc support but this system failed and the film was not released. German film studio UFA got interest to show the film in two parts. Sound was added in German and it premiered in Berlin in 1937. Later, in 1941, Roger Richebé (Paris Cinéma Location) produced a French sound version, which premiered on April 1941. It was the third animated feature film to have sound, after Quirino Cristiani's "Peludópolis" (1931) and "The New Gulliver" (1935) from the Soviet Union.
