Joe Wright's daringly stylized new version of Anna Karenina is staged largely within an actual theater, and uses not only the stage but the boxes and even the main floor - with seats removed - to present the action. Keira Knightly, almost distractingly beautiful here, stars as Tolstoy's heroine. Jude Law is her dry and proper husband, a government minister, and Aaron Taylor-Johnson plays Vronsky, the young military officer with whom she begins a disastrous affair. A sumptuous film, extravagantly staged and photographed, perhaps too much so for its own good. There are times when it is not quite clear if we are looking at characters in a story or players on a stage. - Two and a half stars
