As a side note, Tolstoy would be spinning in his grave over that. He had an intensely moral view of art, regarding both its content and its practical execution. In the book What Is Art? he asserts that opera is an immoral art form because of the tremendous expense involved; he felt that since an equally great artistic achievement could be had through poetry or painting or (minimalistic) theater at a miniscule cost, then massive sums of money shouldn't be spent on operas while people are starving to death.
(Mind you, I'm here, obviously I love movies, I just think it's kind of ironic that the MOST EXPENSIVE MOVIE EVER was a fiercely loyal all-out Tolstoy adaptation)
