Rudolph Nureyev, Karen Kain and Second Cast Rehearse 'Sleeping Beauty' [National Ballet of Canada]

This is footage of Rudolph Nureyev and Karen Kain and of a second cast rehearsing Nureyev’s production of ‘The Sleeping Beauty' for the National Ballet of Canada.
The set designer for this production was to be Nicholas Georgiadis, who Nureyev had used on many enterprises.
What’s interesting for me in this video was hearing Nureyev and Kain discussing technical problems - using highly technical language, like when the ballerina says “if there’s too much yank, I can’t control my force”!
Enjoy!
