Classical Hollywood cinema
The beginning of the sound era itself is ambiguously defined. To some, it began with "The Jazz Singer", which was released in 1927 and increased box-office profits for films, as sound was introduced to feature films. To others, the era began in 1929, when the silent age had definitively ended. Most Hollywood pictures from the late 1920s to 1960s adhered closely to a genre—Western, slapstick comedy, musical, animated cartoon, and biopic (biographical picture)—and the same creative teams often worked on films made by the same studio. For instance, Cedric Gibbons and Herbert Stothart always worked on MGM films; Alfred Newman worked at Twentieth Century Fox for twenty years; Cecil B. DeMille's films were almost all made at Paramount Pictures; and director Henry King's films were mostly made for Twentieth Century Fox. Similarly, actors were mostly contract players. Film historians and critics note that it took about a decade for films to adapt to sound and return to the level of artistic quality of the silents, which it did in the late 1930s.
Lights of New York (1928 film)
Lights of New York is a 1928 American crime drama film starring Helene Costello, Cullen Landis and Eugene Pallette, and directed by Bryan Foy. Filmed in the Vitaphone sound-on-disc sound system, it is the first all-talking full-length feature film, released by Warner Bros., who had introduced the first feature-length film with synchronized sound "Don Juan (1926 film)" two years earlier. The film, which cost $23,000 to produce ("B" picture), grossed over $1,000,000. The enthusiasm with which audiences greeted the talkies was so great that by the end of 1929, Hollywood was producing sound films exclusively.
