EXCLUSIVE: It’s all over but the press release! Almost a month after Deadline revealed that Kevin Costner was in early talks for a lead role in Superman: Man of Steel, I hear that he has closed a deal to play Jonathan Kent, the adoptive dad of Clark Kent. Costner will join Henry Cavill, who is playing the title role, and Diane Lane, who is playing Martha Kent, his adopted mother.

Zack Snyder is directing for Warner Bros and Legendary Pictures. The Superman film is being produced by Chris Nolan, Charles Roven, Emma Thomas, and Deborah Snyder. The screenplay is being written by David S. Goyer based on a story by Goyer and Nolan. Thomas Tull and Lloyd Phillips are serving as executive producers. The new Superman is targeted for release in December 2012.

Now, the speculation will begin on who will play the Superman villain. Early reports had Viggo Mortensen as the likely candidate, but I don’t think that’s going to be possible, if he signs that deal to star with Kristen Stewart and Charlize Theron in Universal Pictures’ Snow White and the Huntsman. Let the guessing game begin! Costner is repped by WME and One Talent Management.
