Avengers: Secret Wars: New Casting, Filming Updates and What Could Happen Next

Marvel's next giant crossover is getting closer. While Avengers: Doomsday is still the immediate focus, Marvel Studios is already moving forward with Avengers: Secret Wars, the movie expected to bring the Multiverse Saga to its biggest point yet. Avengers: Secret Wars is currently scheduled to arrive in theaters on December 17, 2027. Joe and Anthony Russo are directing, and Robert Downey Jr. is expected to return as Doctor Doom after making his debut as the villain in Avengers: Doomsday. Noah Jupe joins Avengers: Secret Wars One of the newest casting updates is Noah Jupe, known for A Quiet Place and Hamnet. Jupe has joined Avengers: Secret Wars in a mystery role. Marvel has not revealed who he will play, but reports describe the role as prominent. That immediately created a new mystery for Marvel fans because Secret Wars has several important characters who could potentially fit a young actor like Jupe. Some possibilities being discussed include Molecule Man, a version of the Beyonder, Franklin Richards or another character connected to Marvel's future X-Men plans. These are theories, not confirmed casting details. And because Secret Wars is a multiverse story, almost any character theory has to be treated carefully. Marvel could easily be hiding a completely different role. Is Avengers: Secret Wars already filming? This is where things get interesting. Earlier in 2026, Joe Russo said Secret Wars was still in pre-production. Later reports indicated that production activity had begun at Pinewood Studios in the UK, followed by a reported five-week break for the crew. Filmbase-related reporting suggested production would resume around the end of September. A newer report now claims that filming is about to get moving again. However, Marvel Studios has not publicly confirmed every detail of the reported filming schedule, so fans should treat the exact production timeline as reported information rather than official confirmation. The timing makes sense. Marvel is currently finishing Avengers: Doomsday, which is scheduled for December 18, 2026, while Secret Wars follows roughly one year later. What could Secret Wars actually be about? Marvel has not revealed the complete story. However, the title strongly connects to the famous Secret Wars comic-book stories. The 2015 version by Jonathan Hickman and Esad Ribić is especially important because it features the destruction of the multiverse and the creation of Battleworld, a strange world made from pieces of different realities. TheWrap reports that Avengers: Doomsday draws from elements of Hickman's Time Runs Out storyline, which leads naturally into the Secret Wars concept. That creates an obvious possibility for the movies. The multiverse could collapse or be heavily damaged during Doomsday. Doctor Doom could then take advantage of the situation and create a new reality from what remains. If Marvel follows anything close to the comic-book structure, Secret Wars could therefore be less about simply saving one universe and more about deciding what the next MCU universe will actually look like. Prediction: Doctor Doom could control the new reality One of the biggest predictions is that Doctor Doom will become the central power of the new reality. In the 2015 comic storyline, Doom becomes extremely powerful and creates Battleworld after the multiverse collapses. Marvel does not have to copy that story exactly, but the concept gives the movie an obvious foundation. My prediction is that Doomsday could end with the heroes failing to completely stop Doom. That would make Secret Wars different from a normal Avengers sequel. Instead of beginning with another simple superhero battle, the movie could open with the heroes already trapped inside a broken or rewritten reality. That would allow Marvel to introduce completely different versions of familiar characters while also bringing together heroes from different universes. Prediction: The X-Men could become much more important The X-Men are another major piece of the puzzle. Marvel has already been building toward a new generation of mutant characters, and Secret Wars is an easy place to bring different versions of Marvel characters together. A possible storyline is that the multiverse collapse allows the X-Men, Fantastic Four, Avengers and other heroes to exist in the same final reality. This could give Marvel a way to move from the Multiverse Saga into a more unified MCU without simply deleting everything that came before. But again, this is a prediction, not confirmed plot information. Prediction: Some old Marvel characters could return Secret Wars is probably one of the few Marvel movies where almost anything is possible. Because the story involves multiple realities, Marvel could theoretically bring back previous versions of characters without saying that their original stories never happened. That could mean appearances from older versions of Spider-Man, Fantastic Four characters, X-Men characters or other heroes from previous Marvel movies. However, no specific surprise return should be treated as confirmed unless Marvel or a reliable industry source announces it. What happens to the MCU after Secret Wars? This may actually be the biggest question surrounding the movie. Anthony Russo has said that, for now, the narrative vision is focused on Secret Wars rather than additional Avengers movies. That does not necessarily mean Marvel will stop making Avengers movies forever. It simply means Secret Wars is currently being treated as the major endpoint of this particular story. The movie could therefore become a bridge between the current MCU and whatever comes next. A reset does not necessarily mean Marvel would erase everything. It could instead use Secret Wars to create a cleaner timeline while keeping selected characters, actors and storylines. The biggest mystery is still Doctor Doom Robert Downey Jr. playing Doctor Doom remains one of the most important parts of the entire story. The actor previously played Tony Stark, so Marvel now has an unusual situation: one of the MCU's most recognizable actors is returning as its biggest villain. The exact relationship between Doom and Tony Stark has not been completely explained publicly. Marvel could make them completely separate characters, connect them through the multiverse, or use the resemblance as an important part of the story. That mystery could become one of the major questions surrounding Doomsday and Secret Wars. What to expect next The next major wave of Secret Wars information will likely come as production continues. Fans should be watching for official casting announcements, set photos, filming reports, interviews with the Russo brothers, and eventually the first official promotional material. But the biggest piece of the puzzle is still Avengers: Doomsday. Until that movie arrives, Marvel can keep almost everything about Secret Wars hidden. For now, one thing is clear: Marvel is building Secret Wars as a massive crossover, and the newly announced casting of Noah Jupe adds another mystery to an already enormous project. If Marvel follows the broad ideas of the comics, Secret Wars could end the Multiverse Saga with the destruction of the old reality and the creation of something completely new. But exactly what survives—and who controls the new universe—may not be revealed until Doomsday arrives. Avengers: Secret Wars is currently scheduled for December 17, 2027.
