This film really does have the best scenes from the best musicals without you having to sit through a hundred different movies.
The film is split into several sections with each section being devoted to either a star or a type of musical although Judy Garland does recieve 2 sections devoted to her, one by a very aged Mickey Rooney covering her early career and one by her daughter covering her classics.
Not only is this film good to watch because of the amazing musical numbers [the Busby Berkley and Zeigfeld ones are AMAZING] but it is also extremely amusing to watch straight actors atempting to sing [Elizabeth Taylor really takes the cake].
Its nice to see all of the hollywood greats coming together to make a movie although Clark Gable and Judy Garland to leave glaring holes where they should have hosted sections and it would have been better if the film were made 10 years earlier as quite a few notably Peter Lawford have passed their sell by date.
All in all it is very nostalgic and brings togethrer the best of the best is a star studded tribute!
