Observations

After reading the book, Madame Valentino, the many lives of Natasha Rambova, I was able to I think spot her in, the Sheik. She said that her and Paul Ivano played Europeans so I knew this meant she would have had to be in the beginning when the Sheik was first coming into Briska. When I first read she was an extra, I read "into it" that she was one of the arab girls. But armed with this new information I looked for her as a "European" with a man (Paul Ivano).
This is where I think you can find her:
Where Diana is getting asked to marry she says, "Marriage to me is captivity. I like the way my life is --" then she sees some comotion and she turns (ending this close up) and the screen fills with people going to see who is showing up. As soon as the screen goes to this shot, look to the far right of the screen. There is a dark haired women with a guy on her left, she is standing up and they head over to the balcony to take a look. I'm sure this is Natasha and Paul Ivano. It's a strange feeling, at least for me, seeing her there. History, and all I've learned about Rudy and this time in his life, unfolding there before my eyes. You can continue to see her standing at the balcony while the Sheik comes up for his first introduction with Diana. You can tell how thin and dainty she is and it's a facinating contrast to the power she had over this movie because of the power she had over it's star.
I tried to copy a screen shot/s of this but I'm not having much luck. I could do it at the office but this new laptop is not cooperating so it'll have to be viewed to see what I'm talking about.

Another observation I had was after reading the book, about the slave bracelet that Rudy still wore till the end of his life and even is with "him" today, wore in the movie The Son of the Sheik. I watched the movie tonight and saw it clear as day, after this was pointed out in the book. I didn't know this --- and he wears the bracelet only during his tender love scenes with Vilma playing Yasmin (and may be wearing it but I'm not positive when he is sending her away --- but he is not wearing it during the 'rape' scene).
But the fact that he wears it during the tender scenes with his costar sort of makes me think he is communicating to Natasha that he was thinking of her and that just warms and breaks my heart at the same time. It is such a brave, intimate and romantic way to reach out to the love of his life, even after all the hurt and sadness their union and separation caused him.

Natasha is so perplexing I still am having a tough time writing about my thoughts about her after reading her bio. I have such a mixture of feelings about the woman and I wish she had more to say about Rudy towards the end of her life (and who's to say she didn't but we just have not been given a report). I also have the strongest feeling that she would just rather be stripped out of Rudy's bio for good. For a woman who craved to be recognized as an artist, she sure hated notoriety.
