Good old Kevin Cardboard is still getting work, well thats nice. Maybe he and Clark will have a nice catch in the yard before Clark flies off. Of all the ways to go with the retool of Superman focusing on his origin seems to be the least entertaining. Do the suits believe the last film failed because we didnt get to see the origin again? Spending and hour and a half with Clark to get 20 minutes of Superman at the end is not why I go to see a movie called Superman.
I like Kevin Costner and while he doesn't have a dynamic range I think he has done a good job in the majority of the roles he has been in.
I really can see him as Jonathan Kent. I think this is a very good casting decision.
