James Gunn is directing Superman: Legacy, but he always needed to direct the DC Universe's first movie for a specific reason. Gunn is now the co-CEO of DC Studios with Peter Safran and working to reboot the franchise after several tumultuous years for Warner Bros. and the superhero brand.

This has understandably made it a top priority for the DC Studios co-CEOs
