James Gunn, writer and director of the off-kilter "Guardians of the Galaxy" films, tussled with various ideas on how to deliver a new take on Superman to the big screen.

When “Superman” aka the Man of Steel aka Clark Kent returns this week, it’s hardly the familiar legend your parents knew.

With Corenswet in place, Gunn recruited Rachel Brosnahan to join the reboot as love interest Lois Lane. British actor Nicholas Hoult — who also auditioned to play Superman — was then cast as Supes’ arch-enemy Lex Luthor.
