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.
Opening credits
The first sound film to begin without any opening credits was Walt Disney's "Fantasia", released in 1940. In the film's general release, a title card and the credit "Color by Technicolor" were spliced onto the beginning of the film, but otherwise there were no credits, although closing credits were added to the 1990 re-release and are on the videocassette. This general release version has been the one most often seen by audiences. In the roadshow version of the film, unseen by most audiences until its DVD release, the title card is seen only at the halfway point of the film, as a cue that the intermission is about to begin. The intermission was omitted in the general release version.
