Hi Antonella, IMO the Collier/Dowell dvd is the best compared to the more recent ones available.
It's one of the few records of Lesley Collier on film, and one of her final appearances as a Royal Ballet
principal. She was a classically pure and regal Sugar Plum. Dowell is also quite excellent in this performance.
Thanks Cygnet, I bought it and can't wait to see it.
