James Gray: best books

James Gray's films include Two Lovers, starring Joaquin Phoenix and ­Gwyneth Paltrow, and Little Odessa and We Own the Night.He named his six best books for The Week.One book on the list:Anna Karenina by Leo Tolstoy (Signet, $7).In my view, Anna Karenina is simply the best novel ever written. A book of authentic emotion, acutely observed and brilliantly executed, with astonishing sweep and power.
