David Corenswet is set to debut as Superman in the upcoming DC Universe film Superman, directed by James Gunn and releasing in July 2025, with a rumored cameo in Supergirl: Woman of Tomorrow showing a flashback scene involving his Superman character. A new character, Baby Joey, confirmed to be Metamorpho’s toddler son, plays a significant role in Superman, with a subplot involving his kidnapping that forces Metamorpho, portrayed by Anthony Carrigan, to choose alliances between Superman and Lex Luthor. The film features a star-studded cast including Rachel Brosnahan as Lois Lane and Nicholas Hoult as Lex Luthor, with additional characters like Mister Terrific, Guy Gardner, and Hawkgirl. Former Smallville Lex Luthor actor Michael Rosenbaum revealed he recorded a secret voice role in the film, possibly as a robot in Superman’s Fortress of Solitude, highlighting James Gunn’s inclusion of regular collaborators in the project. Supergirl: Woman of Tomorrow, directed by Craig Gillespie, adapts a critically acclaimed comic miniseries and includes cast members such as Eve Ridley and Jason Momoa. These interconnected projects mark the beginning of a newly imagined DC Universe under Gunn’s direction, blending epic action and character depth.
