Several DC Comics heroes show up in James Gunn's Superman, including one who was left out of the film's marketing but will play a big role in the DC Universe.

Part of what separates Gunn’s Superman from previous adaptations – good and bad – is that it’s the most comics-accurate screen adaptation to date, taking inspiration from 80+ years of Supes-starring comics, most notably Grant Morrison and Frank Quietly’s mid-2000s masterpiece All-Star Superman.

James Gunn is reportedly considering making two Superman spin-off shows following some of the DCU movie's supporting characters.
