Marvel Studios has yet to reveal who will star in the upcoming Wonder Man series, but fans can expect at least one MCU veteran to return. Ben Kingsley will reprise the role of struggling actor/faux-Mandarin Trevor Slattery.
Variety broke the news of Kingsley’s return. While it’s unknown exactly how Slattery fits into the series, Variety’s sources indicate Kingsley “will play a major role” in the Disney+ project. Given that Wonder Man himself is depicted as an actor and stuntman in the comics, it’s possible Slattery will be portrayed as a mentor or colleague to Simon Williams.
Wonder Man will mark Kingsley’s fourth stint as Slattery. He debuted in the role in 2013’s Iron Man 3. Kingsley was marketed as the film’s main villain, with viewers led to believe he was playing The Mandarin. However, in one of the more memorable examples of the MCU subverting the comic book source material, Kingsley’s character turned out to be a low-level actor hired to play a fictional terrorist leader, thereby disguising the work of “real” Mandarin Aldrich Killian (played by Guy Pearce).
Slattery returned in the 2014 short film “All Hail the King,” which revealed both he and Killian were impersonating the actual Mandarin, an underworld figure who was so angered by their disrespect that he arranged to have Slattery kidnapped from prison. That twist eventually paid off in 2021’s Shang-Chi and the Legend of the Ten Rings, where Slattery returned as a captive court jester to Tony Leung’s Xu Wenwu, before ultimately winning his freedom. Presumably, Wonder Man will chronicle the next step in Trevor Slattery’s strange journey through the MCU.
Shang-Chi’s Deston Daniel Cretton will executively produce the Wonder Man series, with Andrew Guest overseeing the series as head writer. No other cast or crew have been revealed so far.
Cretton looks to have a very busy Marvel schedule over the next several years. He recently signed on to direct Avengers: The Kang Dynasty, which debuts on May 2, 2025, and will serve as the penultimate chapter in the MCU’s Phase 6. Cretton also revealed he’s begun early work on a Shang-Chi sequel, though it’s unclear whether that film will drop before or after The Kang Dynasty.
