Oh, I really don't want to disappoint you, but "Swan lake" will take place in Opéra Bastille - as all Nureyev's ballets in Paris...
I think that Hugo Marchand could be a good Siegfried too, especially if he dances with Dorothée Gilbert - they're great together.
I'm less convinced by Amandine Albisson, who, too often in my opinion, doesn't pay attention enough to her partner - but she's indeed a beautiful dancer, with a strong technique and beautiful lines. Maybe we can hope to see the new "Première danseuse" Héloïse Bourdon, who danced Odette/Odile at the Mariinsky a few years ago.
