The Marvel Cinematic Universe is constantly treating fans to new content, both in theaters and streaming with a Disney+ subscription. While there are plenty of upcoming Marvel movies to look forward to, none have as much hype as The Russo Brothers' Avengers: Doomsday. Fans who spent years watching the Marvel movies in order are thrilled for the teams of superheroes to crossover, and James Marsden revealed which of his co-stars geeked out the most on set about the X-Men.
What we know about Avengers: Doomsday has been limited, but the fact that the OG stars of the X-Men movies are joining the fun has buoyed excitement. During a conversation with IMDb at San Diego Comic-Con, Marsden revealed which members of the Doomsday cast were most excited to be filming alongside the mutants. He responded with:
As far as fans and enthusiasm, probably Chris Evans. Pedro [Pascal] was excited about it. Simu [Liu] was flipping out over my costume.
Honestly, can you blame them? Despite how much genre work this trio of actors has done over the years, even the Avengers and Fantastic Four couldn't help but nerd out over seeing the X-Men on set... especially since they're finally wearing more comic-accurate costumes in Doomsday.
Marsden is playing Cyclops 27 years after filming the OG X-Men, and will be rocking the blue and yellow suit for the first time in the next Avengers movie. Fans are thrilled about this, but it sounds like Simu Liu couldn't get over the new costume either. You can see The Notebook actor's comments about his superpowered co-stars below:
If the cast of Doomsday was freaking out like this, one can only imagine how fans will react when the next Avengers movie hits the big screen this coming December. Fans have waited a long time for the X-Men to finally join the MCU, with Disney's acquisition of 20th Century Fox finally opening the door for characters like the mutants and the Fantastic Four to get in on the action. And while mutants have been gradually peppered in, this will be the first time we see the X-Men assembled in the shared universe.
Avengers: Doomsday's trailer teased what it'll be like when all these teams of heroes collide, including a skirmish between the X-Men and the Avengers. We see Shang-Chi and Gambit come to blows, as well as Yelena and Mystique. I'm eager to see who James Marsden's Cyclops might fight during this conflict, especially cuz he'll finally be rocking the iconic yellow and blue costume from the comics and animated series.
All will be revealed when Avengers: Doomsday hits theaters on December 18th as part of the 2026 movie release list. That's when we'll see how the cast's excitement and nerdiness translate into the final theatrical cut.
