Tom Holland may have built a career on accidentally spilling Marvel secrets, but when it came to Robert Downey Jr.'s shocking return to the MCU, the actor managed to keep one of Hollywood's biggest reveals under wraps—at least from the public. However, there was one person who knew almost immediately: his wife and longtime co-star, Zendaya.
The Spider-Man star recently opened up about learning Downey's closely guarded secret long before Marvel Studios made the official announcement. The revelation came directly from Downey himself during a private phone call between the two actors.
Holland shared that Downey personally reached out to inform him about his highly anticipated return to the Marvel Cinematic Universe, this time not as Tony Stark but as the iconic villain Doctor Doom. The news came as a surprise to fans when it was finally revealed at San Diego Comic-Con, but Holland had been sitting on the information for quite some time.
During a conversation with Cinemania, Holland explained that he and Downey maintain a close friendship and regularly check in with each other. "Robert and I just have casual catch-ups every now and then," the actor said. "He called and told me. It's really exciting."
While Holland successfully kept the news from fans and the media, he admitted there was no way he could keep it from Zendaya. The actress confirmed that her husband shared the news immediately after his phone call with Downey. "Right away," Zendaya stated when asked about when she first learned of the Marvel return. She recalled Holland excitedly telling her, "Downey is coming back."
Holland has long been known for his tendency to accidentally reveal plot details and spoilers during interviews and press tours. The actor has developed a reputation that precedes him, with Marvel Studios often keeping him in the dark about major storylines to prevent any unintentional leaks. This time, however, he managed to hold onto the secret despite being among a very select group of people who knew in advance.
"I don't know a lot about those movies by design," Holland joked during the interview. "I have a reputation for spoiling certain things, and I think the studio is keeping me from the juicy details."
The actor expressed genuine curiosity about how Downey's new role as Doctor Doom will intersect with Peter Parker's journey in the MCU. Holland noted that he is eager to see how the storyline develops and what it means for his character moving forward.
"When I do get to grace that set, I am so curious what that means for Peter and how that works," he said. "It's really cool. I am really excited about whatever it is they are doing."
This is not the first time Holland has addressed the challenge of keeping Downey's return a secret. During a 2024 appearance on the Rich Roll podcast, the actor revealed that he had been among a small circle of individuals who knew about the Marvel comeback well in advance. At the time, he mentioned having frequent conversations with Downey about the exciting development.
"I've been speaking to him a lot, especially about him making his return, which is super exciting," Holland said on the podcast. "That was a tough secret to sit on because I have a reputation for ruining things, and I strategically have done no press."
Holland's careful approach to avoiding press engagements during that period was a deliberate strategy to ensure he did not accidentally let the secret slip. The actor's awareness of his own tendencies demonstrated a newfound level of caution when it comes to handling Marvel's most sensitive information.
The news of Downey's return as Doctor Doom marks one of the most surprising developments in the MCU's history. Downey, who portrayed Tony Stark and Iron Man for over a decade, seemingly concluded his Marvel journey with a heroic sacrifice in Avengers: Endgame. His return as a completely different character has generated significant buzz among fans and industry observers alike.
Holland is set to reprise his role as Peter Parker in the upcoming Spider-Man: Brand New Day. The film brings back several familiar faces from the franchise, including Zendaya, Jacob Batalon, Jon Bernthal, Michael Mando, and Mark Ruffalo. The cast also features newcomers Sadie Sink, Tramell Tillman, Liza Colon-Zayas, and Marvin Jones II joining the Marvel universe.
Destin Daniel Cretton is directing the project, with Chris McKenna and Erik Sommers handling screenwriting duties. The film is scheduled for theatrical release, continuing the beloved Spider-Man franchise that has become a cornerstone of the MCU.
The dynamic between Holland and Downey has been a highlight of the Marvel franchise since the young actor's introduction as Spider-Man in Captain America: Civil War. Their on-screen mentorship and off-screen friendship have resonated with audiences, making Downey's return as a villain particularly intriguing for fans who have followed their characters' journeys.
As production on Spider-Man: Brand New Day moves forward, anticipation continues to build around how Downey's Doctor Doom will fit into the larger Marvel narrative and what it means for Peter Parker's future. Holland's ability to keep this particular secret, despite his reputation, suggests that the actor has learned from past experiences and is taking his role in the MCU more seriously than ever.
For now, fans can look forward to seeing both Holland and Downey return to the big screen in their respective roles, with the connections between their characters poised to create some of the most compelling storytelling in the MCU's upcoming phases.
