Honestly, the first time we saw Wyatt Russell pop up at the end of that first episode of The Falcon and the Winter Soldier, the internet basically had a collective meltdown. You remember it. That wink. The chin. The fact that he was holding Steve Rogers’ shield while wearing a suit that looked just a little too "new car" for comfort.
Fans hated him instantly.

But here’s the thing: that was the point. Wyatt Russell didn't just stumble into the Marvel Cinematic Universe to be a generic placeholder. He was cast as John Walker—the man who would become U.S. Agent—specifically because he could play that "uncanny valley" version of heroism. He looks like a hero, he has the jawline of a hero, but something in the eyes tells you he’s one bad day away from a total catastrophe.
The "Not My Cap" Phenomenon
Social media in 2021 was a toxic wasteland of #NotMyCap hashtags. People were actually sending death threats to Wyatt Russell’s team because they couldn't separate the actor from the guy replaced their favorite Avenger. It was wild. But looking back from 2026, it’s clear that Russell’s performance is one of the most nuanced things Marvel has ever put on screen.
John Walker wasn't a villain. Not at first. He was a decorated soldier, a three-time Medal of Honor recipient, and a guy who genuinely believed he could do the job. But he was a human being trying to fill the boots of a literal legend.
Most MCU characters are either "good" or "bad." Walker was just... stressed. He was the personification of Imposter Syndrome with a side of Super Soldier Serum.
Why Wyatt Russell Was the Perfect Choice
A lot of people don’t realize Wyatt Russell didn't even want to be an actor initially. He was a professional hockey goalie. He played in the Netherlands and Germany. He has this "bull in a china shop" physicality that he brought directly to the role of U.S. Agent.
He once mentioned in an interview that he channeled his former teammate, Milan Lucic, for the character. If you know hockey, you know that means someone who is a literal powerhouse but also a bit of a loose cannon.
There's also the meta-narrative of his own life. Wyatt is the son of Kurt Russell and Goldie Hawn. He spent his whole life being the "replacement" or the "next generation" in the shadow of icons. That feeling of "did I actually earn this or am I just here because of the name?" is something he leaned into for Walker. It made the character’s desperation feel uncomfortably real.
The Shield Incident and the Turning Point
Everything changed when he killed that Flag Smasher in the middle of a public square.
The image of the shield covered in blood wasn't just a shock tactic. It was the moment John Walker died and U.S. Agent was born. He realized he could never be the "symbol" Steve Rogers was. He could only be the weapon the government wanted.
When Julia Louis-Dreyfus’s character, Valentina Allegra de Fontaine, finally gave him that black and red suit, Russell’s reaction was hilarious. He said it felt like a "deflated kid on Christmas" because it was the exact same suit, just a different color. But that color change meant everything. It signaled his move from the light into the grey.
U.S. Agent in the Thunderbolts and Beyond
Fast forward to now. With Thunderbolts and the upcoming Avengers: Doomsday, the perception of Wyatt Russell has shifted.
He’s not the guy we hate anymore. He’s the guy we relate to because he’s a mess. In the Thunderbolts film, we see a John Walker who has humbled himself—sorta. He’s still a bit of a jerk, but he’s a jerk who knows his limitations. He’s become the "blue-collar" superhero.
What’s interesting about the MCU version of U.S. Agent compared to the comics is the humanity. In the comics, John Walker can be a bit of a right-wing caricature. In the movies, thanks to Russell, he’s a guy who just wants to be told he’s doing a good job.
He’s currently the heart of the "New Avengers" or whatever Val is calling them this week. He provides the muscle, but also the vulnerability. Watching him interact with Yelena Belova and Bucky Barnes shows a man who is finally finding a family where he doesn't have to be "perfect."
What's Next for John Walker?
If you're following the 2026 slate, you know Avengers: Doomsday is going to be the ultimate test for this character.
There are rumors—unconfirmed, but persistent—that Walker might finally get a redemptive moment that puts him on par with the original Avengers. Or, he might double down on being the government's hitman. Either way, Wyatt Russell has solidified himself as a staple of the franchise.

He even launched a canned cocktail brand called Lake Hour recently. The guy is busy. But for most of us, he’ll always be the man who made us hate him just so he could teach us something about the burden of being a hero.
Actionable Insights for Fans and Collectors:
- Watch the "Assembled" Episode: If you haven't seen the making-of documentary for The Falcon and the Winter Soldier, do it. It shows Russell’s screen tests and how he intentionally made Walker’s posture look slightly "off" to signal his discomfort.
- Track the Comics: If you want to see where the character might go, pick up the John Walker: U.S. Agent miniseries by Christopher Priest. It’s the closest thing to the "disgraced soldier" vibe we see in the films.
- Keep an Eye on the Shield: Notice the differences between Walker’s DIY shield and the official Vibranium one. It’s a great visual metaphor for his "faking it until he makes it" attitude.
Whether you're a die-hard Marvel fan or just someone who appreciates a good "fall from grace" story, Wyatt Russell’s journey as U.S. Agent is one of the most compelling arcs in modern cinema. He took the most hated man in America and turned him into someone we actually want to see win. Sort of.
