The biopic isn't very exciting, maybe even a little embarrassing, but I noticed that much of the dialog is taken from Meredith Daneman's very good biography of Fonteyn. If you read it and Julie Kavanagh's biography of Rudolf, you will know as much as there is to know about these iconic dancers, personally and professionally. I actually read both of those books twice because Kavanagh's led me to Daneman's, and that made me want to read the Rudolf bio again, etc. Time well spent, too.
The best part of this pair of DVD's is the bonus disk featuring Fonteyn in segments from three ballets. My favorite is Ondine. For a terrific review of the ballets on the bonus disk, I recommend Ivy Lin's review. In fact, read all her ballet DVD reviews, you can learn a lot from them and be guided to some other DVD's you might like to add to your collection. Expert information.
