I think this is the third time reporting on this, but now it is officially official.
Director Zack Snyder released the following statement:
“Jonathan Kent is the only father figure Clark has ever had, the man who was there to help Clark understand what he was meant to do in the world as Superman. Kevin will be able to communicate the quiet strength of this rural American man who raised the greatest superhero of all time.”
In addition to Kevin Costner, we know that Diane Lane will play Martha "Ma" Kent, and of course, Henry Cavill will be the Man of Steel - Superman.
Just yesterday, Snyder mentioned the the direction for this film to be different than the previous and the cast to be, "consistent in its … awesomeness.”
So hopefully we will learn more soon, as there have been a ton of rumors in regards to Lois, Zod - and possibly even Lana. You can head on over to the Cosmic Book News Superman Movie Hub for even more on those stories.
Superman flies into theaters December 2012 directed by Zack Snyder starring Henry Cavill as the Man of Steel, Kevin Costner as Jonathan "Pa" Kent and Diane Lane as Martha "Ma" Kent.
