James Gunn's DCU Redefines Superman's Origin, Sparks Franchise Debate

James Gunn's approach to the DC Universe (DCU) with his 2025 Superman film breaks traditional superhero movie norms by using post-credits scenes as lighthearted, non-plot-setting moments rather than teasers for future projects. The film controversially retcons Superman's origin, revealing a message from his Kryptonian parents urging him to dominate humanity and repopulate Krypton, a narrative that reshapes his heroic purpose and sets up significant implications for upcoming DCU installments, including the sequel Man of Tomorrow. Casting was carefully considered, with David Corenswet selected for his iconic Superman look, highlighting Gunn's challenge in finding the right actor for such a well-known character. Additionally, the DCU introduces heroes like Metamorpho and Green Lantern, who possess abilities capable of defeating Superman, adding complexity to the hero's portrayal as fallible and human. The film also introduces Milly Alcock as Supergirl, sparking fan debate over the age gap between her and Corenswet's Superman, raising questions about character chemistry in future DCU narratives. Gunn has confirmed a standalone Supergirl movie set for 2026, which will include Jason Momoa as villain Lobo, indicating continued expansion and evolution of the DCU storyline.
