One Marvel veteran is back in superhero-ing shape for what seems to be an Avengers: Doomsday appearance. Stars getting jacked to appear in a Marvel movie is nothing new; however, fans using the muscular changes of A-listers to predict who may be or may not be in the next MCU epic has become a relatively recent phenomenon.
Captain America actor Chris Evans is the latest focus of one of these pushes, as he showed up at the Toronto International Film Festival (TIFF) looking particularly svelte, as if he is ready to don Cap's shield yet again. Evans is assumed to appear in the upcoming fifth Avengers film, marking the return of the actor to his Steve Rogers role after more than five years away from the super-powered movie franchise (outside of a hilarious Human Torch cameo in Deadpool & Wolverine).
Evans was spotted at TIFF looking jacked in a slim-fit tee, reiterating to many fans that the actor will, in fact, look the part in Avengers: Doomsday.
Not to say that since leaving the MCU after 2019's Avengers: Endgame, the former Captain America star had let himself go in any meaningful way; however, the actor is looking especially trim in these new photos as if he were ready to don the stars and stripes yet again on-screen.
Rumors of Evans' appearance in Avengers: Doomsday continue to percolate online, with many assuming the 44-year-old will appear in the 2026 MCU team-up.
Insider Daniel Richtman wrote in late August that Evans was reportedly filming scenes for Doomsday in the U.K., with reports that the film will visit Steve and Peggy's house (as seen at the end of Endgame) during its trip across the Marvel Multiverse.
Evans was at TIFF to promote his upcoming film Sacrifice, which premiered as part of the festival's 2025 lineup.
Avengers: Doomsday is set to come to theaters on December 18, 2026. The new MCU film from Avengers: Infinity War and Endgame filmmakers Joe and Anthony Russo follows Earth's Mightiest Heroes in a battle for the Multiverse against the dastardly Doctor Doom (played by MCU vet Robert Downey Jr. in an entirely new role). Downey is said to lead the film, with the likes of Evans, Chris Hemsworth, Anthony Mackie, Florence Pugh, and Pedro Pascal set to round out its super-powered ensemble.
How Will Chris Evans Factor Into Avengers: Doomsday?

Despite not yet being confirmed by Marvel to be part of the Avengers: Doomsday cast, it is widely assumed (especially considering his current state) that Chris Evans will be part of the upcoming Marvel Studios blockbuster.
This may shock some, seeing as it seemed Evans was done with the MCU after the end of the Infinity Saga. The last fans saw of the actor/character, he had travelled back in time, returning the Infinity Stones to their proper locations, and stopping to spend the rest of his days with his beloved Peggy Carter (Hayley Atwell).
This was the happy ending that Evans' Captain America fans have been craving since he was put on ice to end his debut MCU movie, Captain America: The First Avenger. However, it looks like he will be roped back into the action for Doomsday, forced to get back in the suit to take down the terrifying Doctor Doom.
One popular theory about how Evans' Cap could come back into play involves Doom's overall plan to take over the Multiverse. Some speculated that the movie's primary villain would be on the hunt for anyone who had actively messed with it (whether successfully or not).
Cap would fall into that category, altering history for his own personal gain so that he could live out his days with his one true love, whom he previously had to leave behind.
This could see Cap either captured by Doom, fighting against him to save the reality he created, or even breaking bad, playing a unique Variant of his Boy in Blue in a similar twist on MCU canon to having Downey play Victor von Doom.
