9) Metallo
This one you really wouldn’t have picked up on unless you studied the credits at the end of the film.
The Lexcorp scientist (played by Ralph Lister) who explains Kryptonite to Holly Hunter’s Senator Finch is named in the credits as Emmet Vale, the man who turns ex-solider John Corben into Metallo – an enemy of Superman – in the comics.
[zergpaid]Director Zack Snyder had previously revealed that Metallo could have been the main villain in the never-made Man of Steel 2. We assume his creator’s inclusion here is just a nod to that, then, but it might also be hinting at an eventual introduction later on.
Also, when Clark talks to Perry White about how The Daily Planet used to stand for something, White angrily reminds him that “it’s not 1938 anymore.” This isn’t just a randomly-picked date, but is in fact the year that Superman made his first appearance in the pages of Action Comics #1.
