According to an exclusive by The Hollywood Reporter, James Gunn has locked in a pivotal casting choice for “Man of Tomorrow,” the highly anticipated follow-up to “Superman.”

After a competitive series of screen tests, Adria Arjona has secured a mystery role in the developing DC Studios project, though the exact nature of her character remains under wraps.

Arjona’s casting arrives after what The Hollywood Reporter describes as an extensive search process, culminating in screen tests held in Atlanta earlier this month. Among those reportedly in contention were Eva De Dominici, Sydney Chandler, and Grace Van Patten. Early speculation pointed to the character being the comic-book antihero Maxima, though that detail remains unconfirmed.

The sequel will once again be led by David Corenswet as Superman, alongside Nicholas Hoult returning as Lex Luthor. In a notable shift, the film is expected to explore a reluctant alliance between hero and villain as they confront Brainiac, portrayed by Lars Eidinger. The dynamic underscores earlier comments from Gunn that the project would function as much as a Lex story as it is a Superman one.

Returning players from the 2025 film include Rachel Brosnahan as Lois Lane and Skyler Gisondo as Jimmy Olsen, along with Sara Sampaio, Isabela Merced, Nathan Fillion, and Edi Gathegi.

For Arjona, the role marks another high-profile addition to a résumé that has steadily gained momentum across television and film. She drew significant attention for her performance in “Andor” and has moved fluidly between genres with projects such as “Good Omens” and the film “Hit Man.” Her casting in “Man of Tomorrow” positions her squarely within one of the industry’s most closely watched franchise rebuilds.
