James Gunn Confirms the Change Was Intentional
James Gunn has publicly confirmed that this revision was deliberate. He explained that he allowed himself the creative freedom to change aspects of Superman’s story to serve the new DC Universe he envisions. Gunn states that the modification was motivated by a desire to craft a narrative that was "interesting" and "interesting for the DCU," even if it diverged from traditional lore.
Gunn also emphasizes that such changes have precedent in the comics; he believes this particular interpretation can add a new depth to Superman’s character, portraying him as someone grappling with the truth of his origins and the moral dilemmas that come with it.
