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.
Vertigo (film)
In 1996, the film was given a lengthy and controversial restoration by Robert A. Harris and James C. Katz and re-released to theaters. The new print featured restored color and newly created audio, using modern sound effects mixed in DTS digital surround sound. In October 1996, the restored "Vertigo" premiered at the Castro Theatre in San Francisco, with Kim Novak and Patricia Hitchcock in person. At this screening, the film was exhibited for the first time in DTS and 70mm, a format with a similar frame size to the VistaVision system in which it was originally shot. When restoring the sound, Harris and Katz wanted to stay as close as possible to the original, and had access to the original music recordings that had been stored in the vaults at Paramount. However, as the project demanded a new 6-channel DTS stereo soundtrack, it was necessary to re-record some sound effects using the Foley process. The soundtrack was remixed at the Alfred Hitchcock Theatre at Universal Studios. Aware that the film had a considerable following, the restoration team knew that they were under particular pressure to restore the film as accurately as possible. To achieve this, they used Hitchcock's original dubbing notes for guidance of how the director wanted the film to sound in 1958. Harris and Katz sometimes added extra sound effects to camouflage defects in the old soundtrack ("hisses, pops, and bangs"); in particular they added extra seagull cries and a foghorn to the scene at Cypress Point. The new mix has also been accused of putting too much emphasis on the score at the expense of the sound effects.
