I noticed a few Easter eggs that didn't seem obvious until I re-watched my Man of Steel BluRay.
The traditional whooshing sound heard as Superman does his very first flying around in the suit... If I'm not mistaken this is the same sound heard when the original Superman (played by George Reeves) flew in the black and white TV series.
The LexCorp truck that was beat up against by whomever it was; which was a reference to Lex Luthor (who did not appear at all in the movie)
The supposed face morphing when Superman flies in the beam of light... his face changing briefly to resemble the late Christopher Reeve...
Has anyone else noticed these, and by chance seen any others?
