Nobody knew what was about to happen in the summer of 2016. Netflix wasn't even a "prestige" network yet, really. It was just the place where you watched House of Cards or binged old sitcoms. Then, a bunch of kids on bikes showed up. Among them was a skinny, curly-haired kid from Vancouver named Finn Wolfhard. He played Mike Wheeler. Honestly, looking back at Finn Wolfhard in Stranger Things Season 1, it’s wild to see how much of the show’s massive global DNA was carried by a twelve-year-old who recorded his audition from a bed because he was sick.
He was the heart. Seriously. While the show had Winona Ryder for star power and David Harbour for the "grumpy cop" trope, the actual emotional heavy lifting of the first eight episodes fell on Mike. He had to make us believe that a telekinetic girl who barely spoke was worth risking everything for. If Finn didn't sell that connection, the show would’ve been a goofy B-movie homage that people forgot two weeks later.
The Audition That Almost Didn’t Happen
Finn wasn't some polished Hollywood veteran. He was a kid who liked movies. Most people don't realize he actually got the role of Mike Wheeler because of a sick day. He was bedridden with a fever when his parents helped him film a self-tape. You can still find clips of it online if you dig deep enough—he’s wearing a t-shirt, looking a bit pale, but he had this specific energy. It wasn't "child actor" energy. It was "real kid" energy.
The Duffer Brothers were looking for authenticity. They didn't want the Disney Channel sheen. They wanted the grime and the awkwardness of the 1980s. Finn had that. He was fast-talking, a little sarcastic, but deeply earnest. When he was cast, the chemistry read with Gaten Matarazzo (Dustin) and Caleb McLaughlin (Lucas) sealed the deal. They felt like a real group of friends who had known each skipped heartbeat and Dungeons & Dragons rule since kindergarten.
Why Finn Wolfhard in Stranger Things Season 1 Felt Different
In the first season, Mike Wheeler is the "Paladin." That’s his D&D class, and he lives by it. He’s the moral compass. Think about the scene where he finds Eleven in the woods during a rainstorm. It’s dark, it’s creepy, and most kids would’ve run away screaming. But Mike’s instinct is to help.
Finn played Mike with a level of intensity that was almost jarring for his age. He wasn't just "the lead kid." He was a boy dealing with the genuine grief of losing his best friend, Will Byers, while simultaneously navigating the first sparks of a crush on a girl from another dimension. That’s a lot for a middle schooler to process.

The "Eleven" Factor
The relationship between Mike and Eleven is the engine of the first season. Millie Bobby Brown was incredible, obviously, but her character was largely silent. She communicated through stares and nosebleeds. This meant Finn had to do the verbal heavy lifting for two people. He had to explain the world to her—and to us.
He explained what a "friend" is. He explained why you don't tell secrets. He explained the concept of "pretty." In the hands of a lesser actor, those scenes would have been cheesy. Finn made them feel like the most important conversations in the world. When he tells El she’s "pretty... good," the awkwardness is so palpable it hurts. That’s not just good directing; that’s an actor understanding the specific brand of 1980s suburban loneliness.
Behind the Scenes of the Upside Down
The set of Season 1 wasn't the massive blockbuster environment it is now. It was scrappy. The kids were basically living together in Atlanta, and that translated to the screen. Finn has mentioned in various interviews over the years—especially when talking to outlets like GQ or Vanity Fair—that they didn't really think the show would be a hit. They were just kids playing pretend with some weird monsters.
There’s a specific technicality to his performance in Season 1 that often gets overlooked. He had to play "leader" to a group of actors who were all distinct personalities. Gaten was the comic relief, Caleb was the skeptic. Finn had to be the bridge.
- The Bike Chases: Those weren't all stunt doubles. The kids actually spent hours riding those heavy 80s Schwinn bikes.
- The Basement: Most of the basement scenes were filmed on a soundstage, but the chemistry was sparked by the fact that the boys were actually playing those games between takes.
- The Sensory Deprivation Tank: During the climax of the season, Finn’s reactions to the "bath" scene had to ground the sci-fi elements in reality.
The Cultural Shift in Teen Casting
Before Finn Wolfhard in Stranger Things Season 1, casting for teenagers and kids often leaned toward "small adults." Kids who were too perfect, too rehearsed. Finn broke that mold. He looked like a regular kid. He had a lanky frame, messy hair, and didn't seem to care about looking cool on camera.
This performance actually led to him getting cast in IT as Richie Tozier. The directors of IT saw what he was doing in the Stranger Things dailies and realized he could handle the "foul-mouthed best friend" role just as well as the "earnest hero." It started a wave of "80s nostalgia" casting that we're still seeing the effects of today in shows like Paper Girls or movies like Ghostbusters: Afterlife.
Realism Over Polish
One of the most striking things about re-watching Season 1 today is noticing the mistakes they left in. Finn’s voice was right on the verge of cracking. He stumbled over lines sometimes, and the Duffers kept it because that’s how twelve-year-olds actually talk. They don't speak in perfect Sorkin-esque monologues. They stutter. They get frustrated.
In the scene where Mike snaps at Lucas in the junkyard, you can see the genuine anger in Finn's face. It wasn't "acting" in the traditional sense; it was a kid being pushed to his emotional limit. That raw quality is what made the "Justice for Barb" era so intense. People cared because the characters felt like their own siblings or childhood friends.
The Impact on Finn’s Career
Let's be real. If Season 1 failed, Finn probably would have gone back to Vancouver and lived a relatively normal life. Instead, he became the face of a generation. He used that platform to start a band (Calpurnia, and later The Aubreys) and eventually move into directing. But all of that—the Saint Laurent campaigns, the blockbuster movies—starts with Mike Wheeler in a basement in 1983.
What Most People Forget About Mike in Season 1
A common misconception is that Mike was always the "popular" leader. He wasn't. Season 1 goes out of its way to show that Mike, Dustin, and Lucas are at the bottom of the social food chain. They are bullied. They are called names.
Finn’s performance captures that "us against the world" mentality perfectly. When he jumps off the cliff at the quarry to save Dustin—knowing he might die—it’s the peak of his character arc. He isn't doing it because he’s a superhero. He’s doing it because he’s a Paladin. He’s doing it because that’s the code.
Actionable Insights for Fans and Creators
If you’re looking back at this performance for inspiration—whether you're a writer, an actor, or just a die-hard fan—there are a few things to take away from why this specific era of Finn's career worked so well.
For Creators:
Stop trying to make your young characters "cool." The reason Mike Wheeler resonated was his vulnerability. He cried. He got scared. He was honest about his feelings for Eleven (eventually). Authenticity beats "cool" every single time in storytelling.
For Fans Re-watching:
Pay attention to the background acting. In Season 1, Finn is constantly "on." Even when the camera isn't focused on him, he’s reacting to Dustin’s jokes or Lucas’s skepticism. It’s a masterclass in ensemble chemistry.
The Legacy of Season 1:
Finn Wolfhard's work in that first year set the tone for the entire series. It established that Stranger Things wasn't just about a Demogorgon; it was about the terror of growing up and the people who stay by your side when things get weird.
To truly appreciate the evolution of the show, go back and watch the pilot, specifically the scene where Mike first sees Eleven in the woods. Look at the balance of fear and curiosity in his eyes. That’s where the magic started.
