Re: Superman (casting, rumors, pix till release)
Not to mention the parents of Kirk and Spock were cast in the last Star Trek movie, yet there was minimal time spent on their childhoods. Until the movie comes out, any talk about how long will be spent on Clark's childhood is pure speculation.
Except that Kevin Costner and Diane Lane are much more prominent actors than Chris Hemsworth and Jennifer Morrison, so it would be reasonable to expect this film would feature its hero's parents more heavily than Star Trek
