When it was released in 1974, the key appeal of That's Entertainment was that it gave people the chance to see moments from films that they might not have had a chance to see, unless they saw them on first release or lived in a city that hosted plenty of revival screenings.
While the musical numbers are still the main reason to watch, viewed forty years later, when all the films are available on DVD or can be viewed online, it's the connecting material that is more rare and fascinating. Where else can you see Gene Kelly walking through the old MGM backlot, or listen to Fred Astaire express his heartfelt admiration for Kelly's work?
It is those moments, as much the virtuosic song and dance routines, that give That's Entertainment! a timeless quality, rather than feeling like nothing more than an assemblage of old clips.
