I agree with Ceeszi, the Baryshnikov/Kirkland version is beautiful and definetly a must have. I think it´s still available and has a very interesting Snowflake Waltz in it! ( With a young Cinthya Harvey as soloist, if i'm not mistaken).
There is a Kirov Nutcracker with Larissa Lehznina and Victor Baranov, filmed in 1994 at the Maryinsky Theater, wich I like a lot! Kirov corps is perfect, the costumes and sets are beautiful and match perfectly, specially the forest in the Snowflake Waltz. It doesn't has a Sugar Plum fairy. Instead, it seems to be about Clara romantic awakening ( wich a very young and extremely good Lezhnina makes believable ). And Victor Baranov, who is not that famous, plays a handsome prince and is a very competent partner.
I'm interested to Know more about Nutcracker Sweeties, with Birmingham Royal Ballet. I might me able to purchase it in near future but I don't know much about it. I'd love to hear from someone who has seen it!
