Wright planning Atonement reunion for Anna Karenina

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.
