Moviemaker Joe Wright appears to be re-assembling his "Atonement" cast for his ambitious movie adaptation of Leo Tolstoy's masterpiece "Anna Karenina" - Benedict Cumberbatch is confirmed to join Kiera Knightley in the project, while James Mcavoy and Saoirse Ronan are still negotiating roles.
 
Knightley, Aaron Johnson and Jude Law were previously confirmed for roles, while "Sherlock Holmes" star Cumberpatch and "Trainspotting" actress Kelly MacDonald have just been added to the all-star cast.
 
Wright tells ThePlaylist.com, "Kelly Macdonald's confirmed, Benedict Cumberbatch is confirmed. I'm still waiting on Saoirse and James."
 
Insiders suggest Knightley will lead the cast as Anna, Law will play her husband, Alexei Karenin, and Nowhere Boy star Johnson will portray the literary heroine's lover, Vronsky.
