I had no intention to go and see the Anne Karenina movie until my mother-in-law asked for it. I even did not read the book by Tolstoy and the story is not really for me, anyway we went and saw it yesterday. I need to admit, it was really good. The flow of the movie was perfect and i never get bored.
It was interesting to see Keira Knightley as Anna Karenina, she was smiling a lot if you compare to
Pirates of the Caribbean :) no problem with that though.
No need to mention about the way of filming in detail, you should go and see it, in summary, director try to make you feel that all story pictured at a theater scene.
