That's Entertainment!

This was among the last MGM films shot on the studio's renowned back lot, of which there were actually six distinct satellite parcels of land west and south of the main lot (Lot 1). Lot 2, the last of them to serve as a working back lot, was in use until late 1978. Development for residential housing on Lots 3-6 began the year this movie filmed its new material with the studio's stars strolling the various standing sets, which had been allowed to deteriorate for well over a decade before their demolition. This is particularly noticeable in the train station set where Fred Astaire gives his introduction, and Bing Crosby refers to the English Lake area as looking rather "scruffy". On the other hand, the entire purpose of the film is nostalgia, and the use of the 'scruffy' facade, clearly aged and unused, helps to set the tone as one of a brief return to the glamour of the past, even though it was all make-believe.

At the beginning of the film, Frank Sinatra says The Hollywood Revue of 1929 (1929) is the "first all-talking, all-singing, all-dancing movie ever made". In fact, it wasn't; the first was The Broadway Melody (1929), which was released in February, nine months before "The Hollywood Revue" was released. Indeed, by the time of That's Entertainment! III (1994), narrator Gene Kelly was now calling The Hollywood Revue of 1929, "one of the first all-talking, all-singing, all-dancing movies."

Producer Jack Haley Jr.'s credit appears over a still image of his father, Jack Haley, as the Tin Man in the Wizard of Oz.

Some TV prints extend Bing Crosby's segment by adding the musical number "True Love" from "High Society" (1956).
