Joseph in the Land of Egypt (1932)
Joseph in the Land of Egypt was a 1932 film, considered to be the first talkie film in Yiddish. Produced in the United States by Joseph Green and directed by George Roland, the film was intended to exploit the burgeoning Yiddish-speaking theater-going in America by introducing them to the new medium of film. Rather than creating an original film, Green took an Italian silent film of Jewish interest and dubbed it in Yiddish. Green, the producer, also took the starring role of Joseph for himself.
