trailer for "anna karenina"

Here's a story I never thought I'd see adapted once more for the silver screen: Anna Karenina.  Having previously read this 19th century Russian novel by Leo Tolstoy, I have about as much sympathy for Anna Karenina as I ever had for Cathy Earnshaw of Wuthering Heights, which is not much.

But still, I am curious to see how Hollywood will represent this novel.  And if the true main character of the novel, Levin, will make any sort of significant contribution to the story.
