We do know that Henry Cavill plays Clark Kent/Superman, and that Michael Shannon portrays General Zod. Earlier today, Michael Shannon made an appearance on VH1's Big Morning Buzz Live, where he revealed the intriguing news that he won't say, "Kneel before Zod" in director Zack Snyder's reboot.
"I don't say that in the movie."
The actor made the admission after being asked by host Carrie Keagan to incorporate that line into a scene from his first movie, the 1993 comedy classic Groundhog Day. He also made another revelation that his "cod piece" is bigger than Henry Cavill's. We'll take any Man of Steel news we can get.
