Well, Lisa, that Anastasia cartoon was just another Disney attraction, I think there was no pretense of being historically accurate. It just got a lot of little girls interested in the fantasy.
I dislike people who criticise N&A. It was just a movie, after all. It was made to make money, not teach history. I saw it when it first came out and have watched it many times since. I like the film. Beautifully done. Great acting. But it is still just a movie.
As for your Prince, well that was just being a snob.
However, for The Kitchen Boy, if it gets made at all, I hope it will be a quality production. It is a good story, but just that- a story, told well. No doubt if it indeed end up on the screen, there will be plenty here picking it apart. What a waste of time.
