I was positively crazy about this movie about 8 years ago. (I worked at the library and reted it at least twice a week). I'm glad I saw it when I did -- the historical 'whoopsies' would make me nuts now.

Ian McKellan, Alan Rickman & Freddie Finlay were WONDERFUL. As for Greta Scacci? Well, I think she's a great actress, but I don't think she captured all the sides of Alix's personality -- too focused on the anxiety & not enough on the regality. Alix was a force to be reckoned with, and that didn't come through very well in this movie. Her religious devotion was done nicely, though.
Rickman did so well with Rasputin. None of the hokey, overdone hypnotism stuff. His behavior was all over the map, of course, but he managed to thread it all together in a way that doesn't make Rasputin look just plain crazy. Irratic, yet cunning, without being a power-hungry maniac.
And the execution scence is the best I've seen. Let's just say they didn't spare the audience!
