Mickey Mouse
Audiences at the time of "Steamboat Willie"'s release were reportedly impressed by the use of sound for comedic purposes. Sound films or "talkies" were still considered innovative. The first feature-length movie with dialogue sequences, "The Jazz Singer" starring Al Jolson, was released on October 6, 1927. Within a year of its success, most United States movie theaters had installed sound film equipment. Walt Disney apparently intended to take advantage of this new trend and, arguably, managed to succeed. Most other cartoon studios were still producing silent products and so were unable to effectively act as competition to Disney. As a result, Mickey would soon become the most prominent animated character of the time. Walt Disney soon worked on adding sound to both "Plane Crazy" and "The Gallopin' Gaucho" (which had originally been silent releases) and their new release added to Mickey's success and popularity. A fourth Mickey short, "The Barn Dance", was also put into production; however, Mickey does not actually speak until "The Karnival Kid" in 1929 when his first spoken words were "Hot dogs, Hot dogs!" After "Steamboat Willie" was released, Mickey became a close competitor to Felix the Cat, and his popularity would grow as he was continuously featured in sound cartoons. By 1929, Felix would lose popularity among theater audiences, and Pat Sullivan decided to produce all future Felix cartoons in sound as a result. Unfortunately, audiences did not respond well to Felix's transition to sound and by 1930, Felix had faded from the screen.
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.
