That's Entertainment! III (1994) is a documentary film released by Metro-Goldwyn-Mayer to celebrate the studio's 70th anniversary. It was the third in a series of retrospectives that began with the first That's Entertainment! (1974) and That's Entertainment, Part II (1976). Although posters and home video versions use the title without an exclamation mark, the actual on-screen title of the film uses it. In order to provide a "hook" for audiences who by 1994 had become accustomed to viewing classic movies on home video and cable TV (luxuries not widely available when the first two That's Entertainment! films were released), the producers decided to feature film footage cut from famous MGM musicals. Many of these numbers were shown for the first time in That's Entertainment! III.
