I know part of the SR/SV collaboration was Al&Miles wanted to see what the Fortress would look like in the movie so they could do something similar.

And Bryan Singer said he deliberately didn't show a teen-aged Clark in the film because he felt that SV had covered that angle well enough. He said that since SV has been keeping the Superman torch alight for the past 5 years he didn't want to step on SV's toes since for many, it's the only knowledge they have of Superman.
