Last we heard about casting for Zack Snyder's Superman reboot, both Kevin Costner and Viggo Mortensen were being looked at for separate roles. Those names, however, are just suggestion; there's no guarantee that come time to start production they will be in the film. This new piece of news isn't speculative, it's definitive.

Deadline has received a press release from Warner Bros. announcing that Diane Lane has been cast as Superman's Earthly mother, Martha Kent, in the new Superman movie, which still has no official title. Lane will join Henry Cavill as the only other official cast member, Cavill, of course, playing the titular hero. As the story goes, Martha, along with her husband Jonathan, discovered the crashed rocket of the Kryptonian alien known as Kal-El and raised him as their son, always knowing that he was different. Costner, who may not have even been approached about the role yet, has been suggested to play the role of Jonathan Kent.

In addition to being stunningly beautiful, Diane Lane is an incredible actress who always elevates the work that she does. While have to imagine that there are some people out there that don't like the idea of her in the role (this is casting of a comic book movie after all), I personally love it.
