Who was the girl you posted awhile back, the Latin American star? She was lovely! She could play young Zenaida, and possibly be aged. I always thought Kirstie Alley (if her diet succeeds a little more) would make an excellent Zenaida, especially older, like the time Nikolai was shot up to the Rasputin stuff and the revolution and exile. I think Kirstie looks a bit like her in the face, and some of her past acting jobs (like Virgilia Hazard in North and South) make me think she could handle the emotional parts well.
