James Gunn’s Adria Arjona secret faces a no-win moment now

Days after actor Frank Grillo shared a slick fan-made poster that pictured Adria Arjona as Wonder Woman , James Gunn jumped onto Threads to swat it down. He said Grillo had no inside information about Arjona’s part in the next Superman movie, and even posted a screenshot of Grillo apologizing for the post. The denial didn’t slow the chatter; it supercharged it.

The speculation around Arjona started months ago with something as simple as Gunn following her on Instagram. Fans connected dots, then Gunn tried to cool things off in an interview —while also noting she’d make a great Wonder Woman. Not long after, Arjona was officially cast in Man of Tomorrow in a role the studio won’t name, and her training teases only poured fuel on the “Is she Diana Prince?” fire. Another theory in circulation: she could be Maxima, the alien queen from DC lore.

How the rumor caught fire

• Gunn follows Arjona on Instagram, sparking casting talk.
• In an interview, Gunn downplays the follow but says she’d be a great Wonder Woman.
• Arjona boards Man of Tomorrow in an undisclosed role.
• Fan speculation splits between Wonder Woman and Maxima.
• Grillo posts fan art showing Arjona as Wonder Woman; Gunn replies on Threads that Grillo has no inside info and shares an apology screenshot.

Why it’s a headache for DC

Here’s the bind for DC Studios. If Arjona isn’t Wonder Woman, months of fan expectations set up a letdown—especially with the character being part of DC’s “Trinity. ” If she is, the theater reveal that Gunn seemingly wanted is already spoiled, and his firm pushback on Threads risks looking like misdirection to protect the surprise. Either way, the mystery has become the story.

Meanwhile, the movie itself keeps getting drowned out. The buzz has centered on Arjona’s identity instead of the sequel ’s rumored storyline—Superman crossing paths with Lex Luthor again to take on Brainiac —and other casting whispers, like Matthew Lillard reportedly joining in a secret role. Those details haven’t gotten nearly the same traction as the Wonder Woman guessing game.

Arjona’s role in Man of Tomorrow remains officially unannounced.

Warner Bros. ’ DC has not revealed when it will name Arjona’s character, and the marketing campaign for Man of Tomorrow hasn’t started yet.
