The Main Street Cinema is a small movie theater located on Main Street, U.S.A. at Disneyland. The theater plays Disney shorts on six different screens while a recorded musical accompaniment plays. Five of the six shorts are played without sound; these shorts are changed from time to time. The sixth short is always Mickey Mouse's 1928 cartoon classic Steamboat Willie, which is played with its original sound, albeit in an edited version to remove objectionable content, but it does include an introduction prepared for a 1950s reissue reminding the viewer when the short was filmed and opened, and that it is still screening today worldwide (ironically now in an age of digital, DVD, and the internet[why?]). In 2010, for the 55th Anniversary of the Park, Opening Day footage was shown.
