Wonder Woman Casting Rumors Heat Up as Fans Suspect James Gunn Secretly Picked Adria Arjona for the Role

DC fans are convinced the DCU's Wonder Woman will be played by Adria Arjona after she posted a video of her workout routine ahead of Man of Tomorrow. As the DCU navigates its ups and downs, all eyes are on DC Studios co-CEO and director James Gunn to deliver next year's Superman sequel.

Mixed in with a variety of other superhero parts – including Milly Alcock's Supergirl, Aaron Pierre's John Stewart, and Xolo Maridueña as Blue Beetle – Arjona was previously said to be playing the role of DC deep cut Maxima.

She reportedly landed the part in April of this year, but fans think Gunn and company are misleading fans in hopes of a big Sadie Sink/Spider-Man-style surprise with Man of Tomorrow. Rumors that her role would eventually be revealed as Wonder Woman surfaced shortly after her casting, but nothing has stoked the flames quite like a video posted by Women's Health yesterday.

The seven-minute highlight showed Arjona's "intense boxing and strength workout," letting viewers peek into how she trains for the parts she plays. Although she explicitly mentioned that training helped her prepare to play Celeste in Onslaught, a later segment brings her rumored DC career into focus.

"I've never felt strong, but it's hard," Arjona said as headlines related to Wonder Woman rumors flased on the screen. "Well, I think the excitement of playing the woman I'm playing gives me everything I need to wake up.

Physically, it's exhausting, but it's all for the better good. The better good? Is that English? The greater good! " The emphasis, of course, is on "the woman I'm playing. " The footage of her intense workout routine coupled with that one specific line has turned everyday rumors into a full-blown whirlwind of speculation, and fans aren't letting up.

She's soo playing Wonder woman https://t. co/UCm8hNAjdI pic. twitter. com/uR945bnntP — ~ (@toiinfinite) September 4, 2026 “The woman I’m playing” …Holy shit you are playing Wonder Woman pic. twitter. com/q8uP3Banml — Alex From Florida ☽☾ (@floridian_alex) September 4, 2026 Adria Arjona's response to a fan calling her Wonder Woman at the 'Onslaught' Q&A "Thank you guys so much for coming" pic.

"This is Wonder Woman. " "Again, we all know she is Wonder Woman but it would be so hilarious if she was doing all this for Maxima," another person joked.

The internet thinks Arjona at least already looks like she could feasibly weild the Lasso of Truth as Diana Prince, but she's not been confirmed to play Wonder Woman just yet. However, it's that very mystery that has fans all riled up – but some of Gunn's comments aren't helping, either.

In July 2025, nearly one year before Arjona joined the Man of Tomorrow cast, fans caught wind that the DC director had started following the actress on Instagram. What was written off as a reach then has now been reassessed, and Gunn's comments at the time might be very telling when it comes to the future of the DCU.

Honestly that’s a good way to tell if you made a great casting decision when you announce Adria Arjona is in the film and everyone immediately clocks that it’s for Wonder Woman lol — MaceAhWindu (@MaceAhWindu) September 4, 2026 DC really cooked with this Wonder Woman casting….

Simply no notes 10/10 pic. twitter. com/3fNM8bcZPp — Jin x Supreme ❤️‍🔥 (@Jinsakuu) September 3, 2026 "I followed Adria Arjona on Instagram, but everybody came out, 'He just followed her, that means she’s Wonder Woman!

That means she’s Wonder Woman! '" he said. "She’d be a great Wonder Woman, by the way. But she was in a movie that I made seven years ago. We’ve been friends and have known each other since that time. I followed her then, I didn’t just follow her.

People just notice these things all the time. " So, Arjona is keeping her role in the Superman sequel a secret, fans think she looks like a great Wonder Woman, and even Gunn admitted she'd be great for the role. If DC Studios has indeed cast her for one of the biggest members of the Justice League, then it might want to play its cards a little closer to its chest.

No matter what internet sleuths uncover, though, it doesn't change the fact that Gunn and the DCU have not currently named their Wonder Woman. Hopefully, we won't have to wait much longer to find out more, though. HBO Max show Lanterns has revealed more about the comic book universe with each episode, with more set to peel back even more layers in the weeks ahead.

Clayface will take things even further when it arrives this October. While we wait for Superman to return with Man of Tomorrow on July 9, 2027, you can see everything else DC has in the works here. You can also see what former Wonder Woman actress Gal Gadot had to say about her separation from DC.
