In my opinion one of the more interesting dynamics of the Superman series has been watching how the creators answer the question "Who is the real person and which is the alter ego?" ... There are essentially 4 different answers to this question, Superman is the real person and Clark Kent is the alter ego, Clark Kent is the real person and Superman is the alter ego, both are the real person and he is conflicted, and neither are the real person.
With the trailer being released with 2 different voice overs, one from each of his fathers, each having 2 different messages I have a feeling that the portrayal will take the more interesting approach where both Superman and Clark Kent are real parts of the same character. This would mean that Clark Kent would not be portrayed as an individual who was so meek and helpless that, in spite physical similarities, no one could imagine him being Superman; and may be a character that is far more whole.
