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.
Atlantic (film)
"Atlantic" was one of the first British films made with the soundtrack optically recorded on the film (sound-on-film), and was Germany's first sound movie feature. In England, it was released in both sound and silent prints. The French version was the fourth French feature with sound-on-film.
