Alan Tudyk actually improvised this scene

Superman marks the beginning of DC Studios’ rebooted cinematic universe under James Gunn, introducing a new version of the Man of Steel for a new generation. Starring David Corenswet as Clark Kent and Rachel Brosnahan as Lois Lane, the film skips the traditional origin story and instead drops viewers into a world where Superman already exists—still learning how to balance his Kryptonian identity with the human values that shaped him. The story leans heavily into hope, kindness, and humanity, portraying Superman not just as a powerful hero, but as a symbol of optimism in a world that constantly questions him. Meanwhile, Nicholas Hoult’s Lex Luthor challenges Superman on an ideological level, pushing themes about morality, perception, and responsibility rather than relying only on physical conflict. The film also carries a lighter and more sincere energy behind the scenes. One fun example involves Alan Tudyk, who voices one of Superman’s robots. During filming, Tudyk reportedly improvised the name “Gary” for Robot 4, and although there was debate about keeping the joke, Gunn loved it enough to leave it in the final cut—an ad-lib that even made cast members break character laughing on set. Moments like that reflect the tone Gunn seems to be aiming for with the new DC Universe: heartfelt, hopeful, character-driven, and unafraid to have fun along the way.
