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.
Njai Dasima (1932 film)
This was the first sound film released by Tan's, but far from the first in the Indies. The earliest sound films released in the Indies, "Fox Movietone Follies of 1929" and "The Rainbow Man", were both shown in 1929. The following year, a domestic part-talkie, G. Krugers' "Karnadi Anemer Bangkong", was also released, becoming the first domestic sound film. Two other directors had followed with full-talkies in 1931: The Teng Chun with "Boenga Roos dari Tjikembang" and the Wong brothers with "Indonesia Malaise". In order to ensure the quality of the sound, Tan's hired Krugers and his single-system camera to do the cinematography and sound direction for this black-and-white film.
