during which period did hollywood convert to sound film production
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.
The Sound of Music The original Broadway production, starring Mary Martin and Theodore Bikel, opened in 1959[1] and won five Tony Awards, including Best Musical, out of nine nominations. The first London production opened at the Palace Theatre in 1961. The show has enjoyed numerous productions and revivals since then. It was adapted as a 1965 film musical starring Julie Andrews and Christopher Plummer, which won five Academy Awards. The Sound of Music was the last musical written by Rodgers and Hammerstein; Oscar Hammerstein died of cancer nine months after the Broadway premiere.
