Snyder said Costner will effectively play the role of the man who raised Clark Kent as his own son.
"Kevin will be able to communicate the quiet strength of this rural American man who raised the greatest super hero of all time," Snyder said.
Costner will star alongside Diane Lane, who plays his wife, Martha, and the film's star, Henry Cavill, who will play Clark Kent, Superman.
The movie will be distributed worldwide by Warner Bros. Pictures.
