I think the trailer sucks. And the whole I give earth my only begotten son bit is rather blasphemous, considering superman was sent here because Krypton was going to be destroyed and not to save the humans. ANd is that Anthony Hopkins voice as Supermans dad?
I guess it is Marlon Brandos voice. Weird.
They spliced together voice clips from the original Superman 1 and 2 so Brando's voice would still be a part of the movie. Brando's voice over is misleading since part of the words were from both movies. The implied 'begotten son' is a trick of the current director. Very clever editing.
