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.
The Sound of Music (film)
In 1966, American Express created the first "Sound of Music" guided tour in Salzburg. Since 1972, Panorama Tours has been the leading "Sound of Music" bus tour company in the city, taking approximately 50,000 tourists a year to various film locations in Salzburg and the surrounding region. The first "Sing-along Sound of Music" revival screening was at the London Lesbian and Gay Film Festival in 1999, leading to a successful run at the Prince Charles Cinema which is ongoing as of 2018. During the screenings, audience members are often dressed as nuns and von Trapp children and are encouraged to sing along to lyrics superimposed on the screen. In July 2000, "Sing-along Sound of Music" shows opened in Boston and Austin, Texas. Some audience members dressed up as cast members and interacted with the action shown on the screen. The film began a successful run at the Ziegfeld Theatre in New York City in September 2000, with the opening attended by cast members Charmian Carr (Liesl), Daniel Truhitte (Rolfe), and Kym Karath (Gretl). "Sing-along Sound of Music" screenings have since become an international phenomenon.
