There are various books about the golden years at MGM, but this is far and away the best I've ever read. It is an exhaustive look at how each of the great MGM musicals was made, with all sorts of info from producer Arthur Freed's private files -- the costs, the money made or lost, etc. (Imagine, an author who actually went and spoke to the people he was writing about, as opposed to a mere gossip gatherer!) There is lots of solidly researched behind the scenes material, making this believable as well as readable. Loads of great photos you won't see elsewhere. For musical film buffs, this is essential reading!
