All the cameos you missed in 'Superman,' and why they're relevant in the new DC Universe

The recently released Superman not only marks the official launch of the new DC Universe led by James Gunn and Peter Safran, but has also surprised audiences with a series of strategic cameos that foreshadow the narrative framework of the comic book adaptation franchise's universe.

One of the most notable is John Cena 's portrayal of The Peacemaker , who appears in a television interview filled with irony and criticism of Superman. This brief appearance cements the connection between the film and the second season of the superhero series (HBO Max), already confirmed by Gunn himself.

Frank Grillo also joins the cast as Rick Flag Sr., showcasing his role in ARGUS and reinforcing his strategic presence in the new audiovisual ecosystem, where he also connects with Monster Command . Along with them, Sean Gunn, brother of the director and Kraglin in Guardians of the Galaxy (Marvel) plays Maxwell Lord, in a brief appearance that suggests his future relevance as a financial mastermind and possible antagonist in other installments of the shared universe.

But if there's one cameo that stands out for its emotional charge, it's that of Jor-El and Lara, played by Bradley Cooper and Angela Sarafyan , who appear in the Fortress of Solitude through a holographic message manipulated by Lex Luthor.

The closing scene stars Milly Alcock as Supergirl , who appears in a final scene alongside Krypto and delivers a line that makes it clear that her role will be central to the next film. Supergirl: Woman of Tomorrow , expected in the summer of 2026. This appearance not only confirms the light and youthful tone that her story will have, but also establishes a direct link with David Corenswet 's Superman.
