Costner is Jonathan
 

I heard that, was posted on fanboy week or so ago.. he's a great actor in certain roles, kind of a box officer blower as of late though... could be good choice for a contending actor, but will never ever be a Marlon Brando.

I never would have thought of him as Jonathan Kent off the top of my head, but thinking about it here, I think he's a great choice for that role.
