Warner Bros. and Legendary Pictures are aiming to get the pic into production this summer and made this announcement:
Warner Bros. Pictures and Legendary Pictures announced today that Oscar®-nominated actress Diane Lane will play Martha Kent, the only mother Clark Kent has ever known, in the new Superman movie to be directed by Zack Snyder.
Zack Snyder stated, "This was a very important piece of casting for me because Martha Kent is the woman whose values helped shape the man we know as Superman. We are thrilled to have Diane in the role because she can convey the wisdom and the wonder of a woman whose son has powers beyond her imagination."
Diane Lane earned an Academy Award® nomination for her performance in the 2002 drama Unfaithful. She most recently starred in the family hit Secretariat. She next stars in the HBO feature Cinema Verite, opposite Tim Robbins and James Gandolfini. Diane Lane's long list of film credits also includes Nights in Rodanthe, Hollywoodland, Must Love Dogs, Under the Tuscan Sun, The Perfect Storm, My Dog Skip, Chaplin, The Cotton Club and A Little Romance, to name only a portion.
Charles Roven, Emma Thomas, Christopher Nolan and Deborah Snyder are the producers of the film. The screenplay is being written by David S. Goyer based on a story by David S. Goyer and Christopher Nolan. Thomas Tull and Lloyd Phillips are serving as executive producers.
Slated for release in December 2012, the new Superman movie will be distributed worldwide by Warner Bros. Pictures, a Warner Bros. Entertainment Company."
