James Gunn's follow-up to last summer's Superman, has cast its final major character. However, it seems that character might not be what anyone's expecting. You might have to wait until Man of Tomorrow hits theaters next summer to find out.

According to reports, Adria Arjona (Hit Man) has been cast in Man of Tomorrow. Other actresses rumored to be up for the role were Eva De Dominici, Sydney Chandler, and Grace Van Patten. Last week, the role became part of a storm of controversy; while one outlet reported that Arjona, Ella Purnell, and Marisa Abela were testing for the mystery role, Gunn later denied the report.

After it was retracted, another outlet provided a different list of names that was pointedly not denied by Gunn.

On top of this, while the role was initially reported to be Maxima, an alien queen who has been both friend and foe to the Man of Steel, it is now being reported that may not be correct.

This will only add fuel to the fire of speculation that the mystery role is in fact Wonder Woman, the premier heroine of the DC cosmos and the star of multiple films in the prior DC cinematic universe.

A film starring the new incarnation of Wonder Woman is reportedly in the works at the studio.

Furthermore, Gunn previously stated that Arjona, who starred in his film The Belko Experiment, would be "a great Wonder Woman."

While many specifics about 'Man of Tomorrow' are being kept under wraps, some crucial details have emerged.

Gunn has clarified that the film is not a direct sequel to 'Superman'. The plot will revolve around the Man of Steel, portrayed by David Corenswet, being compelled to form an unlikely alliance with his arch-nemesis, the megalomaniacal tycoon Lex Luthor, played by Nicholas Hoult.

Their combined efforts will be required to defend Earth from an even greater, super-intelligent alien threat: Brainiac, brought to life by Lars Eidinger.

The ensemble cast further solidifies the film's potential. Alongside the central trio, several other DC characters are confirmed to appear.

These include Superman returnees Guy Gardner, played by Nathan Fillion; Hawkgirl, portrayed by Isabela Merced; and Mr. Terrific, with Edi Gathegi in the role.

Aaron Pierre will debut as John Stewart, a character set to appear first in HBO Max's 'Lanterns' this spring.

The film will also feature familiar Superman supporting characters: Lois Lane, played by Rachel Brosnahan; Jimmy Olsen, with Skyler Gisondo; and Eve Teschmacher, portrayed by Sara Sampaio.

'Man of Tomorrow' is directed and written by James Gunn, with Peter Safran also serving as a producer.

The film is officially slated for release in theaters on July 9, 2027, promising a fresh take on the DC Universe with its blend of action, sci-fi, and superhero storytelling.
