James Gunn's upcoming Superman film is heavily influenced by various iconic Superman comics and series, including All-Star Superman, Kingdom Come, and Superman: The Animated Series. Leaked set photos reveal the presence of Green Lantern Guy Gardner and Hawkgirl in primitive versions of their iconic outfits, potentially hinting at a broader DC Universe integration. Speculation arises around Maxwell Lord potentially forming the Justice League International in the movie, indicated by the LordTech logo seen on costumes and set signage. Additionally, set photos hint at a possible twist involving Ultraman as a villain in the film, leading to fan theories and anticipation for the 2025 release.
