Thank you so much for the heads up, volcanohunter!
I'm a member, but I missed that some of these docs even existed. I've been watching the "Balanchine in Paris" one, which opens with Ghislaine Thesmar coaching Isabella Ciaravola and Herme Moreau in all the second movement of "Palais de Cristal" except most of the central coda solo for the ballerina. Comparing it to the recent broadcast that's available online (on culturebox), aside from a few arms, it looks identical until the end, where there are a few changes. For example the little lifts after the penche/battement/supported lunges, and now there's no jete lift after the back lifts on the diagonal, just runs.
Thesmar, in the one of the first interview portions, said that she overhead her husband, Pierre Lacotte talking to Balanchine. Lacotte asked why Balanchine didn't revive "Palais de Cristal," and Balanchine told him he'd forgotten it, and didn't have the same kind of dancers with the same technique when he made "Symphony in C," and the interview cleverly segues into a segment where Alicia Markova coaches Myriam Ould-Braham in "Le Chant du Rossignol" through a translator. (Later we find that Delouche continues to use Thesmar's commentary to tie the documentary together.) It's interesting how much motivation and story she's trying to convey. It's fascinating to see the choreography. I don't even thing he used the same vocabulary in the one version of "Firebird" I saw.
Vyroubova coaching Muriel Hallé and in "La Sonnambula is fascinating, and there are some short old film clips of her performing the Sleepwalker. Milorad Miskovitch simultaneously coaches Valéry Colin.
The last segment is Verdy coaching Lucia Lacarra and Cyril Pierre in one of the Part 1 PdD from "Liebeslieder Walzer" that was choreographed for her, followed by the big Part 2 PdD.
Best quote, "You purr!"
I'm pretty sure the Verdy with Lourdieres footage is from one of the other Delouche documentaries, where Verdy coaches "Sonatine."
