You know that specific kind of rage you get when you’re watching a character who is just the absolute worst? I’m not talking about a cartoon villain twirling a mustache. I’m talking about the guy who reminds you of your college ex’s pretentious friend, the one who swirled his wine glass too aggressively and corrected your pronunciation of “film noir.” That was me in the spring of 2020. I was locked down, stressed out, and bingeing Normal People on Hulu like my life depended on it. I was rooting for Connell and Marianne with every fiber of my being. And then, Jamie walked in.
Fionn O’Shea played Jamie with such skin-crawling accuracy that I remember literally yelling at my television. I turned to my roommate—who was also deep in the trench of quarantine boredom—and said, “If I ever see that guy in real life, I might have to cross the street.”
But here is the kicker: that reaction? That visceral, gut-level hatred? That is the mark of a genius at work. Fionn O’Shea isn’t Jamie. In fact, by all accounts, he’s a lovely guy from Dublin. But he tricked millions of us into despising him. That kind of talent is rare. It’s dangerous. And it’s why we need to talk about him.
This isn’t just a bio. This is a deep dive into how a young Irish actor managed to become the internet’s favorite villain, only to pivot and break our hearts in the best way possible. We’re going to look at the man behind the sneer, the training behind the talent, and why Hollywood is currently obsessed with Irish men.

Key Takeaways

- A Leader in the Irish Wave: He stands shoulder-to-shoulder with Paul Mescal and Barry Keoghan as part of a golden generation of Irish screen talent.
- From Indie to Blockbuster: His career trajectory has moved smartly from critical darlings like Handsome Devil to massive productions like Cherry.

Who is the real Fionn O’Shea, and where did he come from?
It’s easy to assume that actors just spawn into existence on the red carpet, perfectly styled and holding a glass of champagne. But the reality is usually a lot more grounded. Fionn O’Shea is a Dubliner, born and bred. He came into the world in 1997, growing up in a city that is practically bleeding culture.
I’ve spent decent chunks of time in Dublin. There is a specific energy there. It’s a place where storytelling is the currency. You can’t walk into a pub without hearing a yarn being spun in the corner. It makes sense that O’Shea would gravitate toward acting. It’s in the water.
He attended Gonzaga College in Ranelagh. Now, for those outside of Ireland, that name might not ring a bell. But it’s a school with a reputation. It’s the same halls that Andrew Scott—Moriarty himself—walked through. There must be a drama teacher there who deserves a massive raise, because the talent output is ridiculous.
O’Shea wasn’t just stumbling into this. He was working. He was a child actor, but not the “Disney Channel” kind. He was cutting his teeth in Irish productions, learning the rhythm of a set, figuring out how to be small and truthful on camera. He didn’t chase the Hollywood flashing lights immediately. He stayed grounded in the Irish scene, which I think is crucial. It gave him a foundation of authenticity that you just don’t get when you grow up on a soundstage in Burbank.
Why was Handsome Devil the defining moment of his early career?
If Normal People was his explosion onto the global stage, Handsome Devil was the lighting of the fuse. Released in 2016, this movie holds a special place in my heart. I caught it on a whim one rainy Sunday, scrolling endlessly through Netflix, trying to find something that wasn’t a grim true-crime doc.
O’Shea plays Ned Roche. Ned is the antithesis of the toxic masculinity that surrounds him at a rugby-obsessed boarding school. He’s dyed his hair, he loves music, and he has zero interest in chasing a ball around a muddy field.
Here is why this performance floored me: O’Shea didn’t play Ned as a victim. It would have been so easy to play him as weepy or pathetic. Instead, O’Shea gave him a spine of steel. Ned was witty. He was sharp. He used his words as armor.
- The Chemistry with Andrew Scott: Playing opposite Andrew Scott (who played the teacher, Mr. Sherry) is a tall order for a young actor. Scott eats up the scenery. But O’Shea held his ground. Their scenes together had a genuine mentorship vibe that felt earned, not forced.
- The “Odd Couple” Dynamic: His rapport with Nicholas Galitzine, who played the star rugby player Conor, was electric. They captured that awkward, tentative dance of male friendship where nobody quite knows the rules.
When I finished that movie, I hopped straight onto IMDb. I needed to know who this kid was. I saw “Fionn O’Shea” and thought, “Okay, I’m tracking this guy.” He had a vulnerability that felt uncomfortably real. He wasn’t acting like a lonely teenager; he was the lonely teenager we all felt like at some point.
How did he manage to make Jamie so incredibly hateable?
Let’s get back to Jamie. The character that launched a thousand angry tweets. When Normal People dropped, the world fell in love with Connell and Marianne. They were broken, beautiful, and complicated. And then there was Jamie.
Jamie represents a very specific, insidious type of evil. He isn’t a murderer. He isn’t a criminal mastermind. He is just a privileged, manipulative narcissist who likes to make people feel small.
I remember watching the scene in Italy. The dinner scene. The way Jamie looks at Marianne, the way he subtly belittles her while swirling his wine—it made my skin crawl. O’Shea made a brave choice here. He didn’t try to make Jamie “cool.” He didn’t try to give him a redeeming “bad boy” edge. He played him as pathetic.
He leaned into the nasally voice. He leaned into the sneer. He let himself be the villain.
There is a story that circulated online—maybe you heard it—about how even his own friends were texting him saying, “I know it’s you, but I want to punch you.” That is the highest compliment an actor can receive. It means the transformation was total. He sacrificed his vanity for the story. In an era where every young actor wants to be the hero or the heartthrob, O’Shea stepped up and said, “No, I’ll be the prick.” And he nailed it.
Is he the secret weapon of the “Irish Wave”?
We need to zoom out for a second. Have you noticed that Irish actors are taking over? It’s not just in my head. Cillian Murphy just won the Oscar. Paul Mescal is everywhere. Barry Keoghan is terrifying us in Saltburn.
Fionn O’Shea is the secret weapon in this arsenal.
While Mescal brings the brooding intensity and Keoghan brings the chaotic energy, O’Shea brings the precision. He is the character actor of the group. He is the Philip Seymour Hoffman to their Brad Pitts.
I think this “Golden Age” of Irish talent comes down to storytelling tradition. I was talking to a friend of mine from Cork recently, and he put it perfectly: “We don’t have the budget for explosions, so the script has to be good.”
O’Shea grew up in that environment. He learned that the story is king. You can see it in his choices. He isn’t picking roles based on how cool the poster will look. He is picking roles based on the complexity of the human condition. He fits into this wave not by being the loudest, but by being the most adaptable. He grounds the fantastical elements of the industry with a distinctly Irish realism.
Why is Dating Amber a masterclass in comic timing?
After playing the most hated man on television, what does O’Shea do? He pivots to a comedy set in 90s Ireland. Dating Amber is a joy. If you haven’t seen it, stop reading this and go rent it. Seriously.
O’Shea plays Eddie, a closeted kid who is terrified of his own shadow. He enters a fake relationship with Amber (played by the brilliant Lola Petticrew) to get the bullies off his back.
Comedy is terrifyingly hard. You can’t fake rhythm. You either have it or you don’t. O’Shea has it in spades.
I laughed so hard I choked on my coffee during the scene where he’s trying to learn how to “walk straight.” The physical comedy he brings to Eddie is genius. He walks like a baby giraffe learning to use its legs. He makes himself small, hunched over, eyes darting everywhere.
But what makes the comedy work is the tragedy underneath it. We laugh because we are worried for him. We laugh to break the tension. O’Shea understands that the best comedy comes from pain. He played Eddie with such desperate sincerity that the absurdity of the situation became hilarious. It was a 180-degree turn from Jamie, and it proved that he wasn’t a one-trick pony.
Does his fashion sense reveal more than his interviews?
I’m a bit of a fashion nerd. I like seeing what guys wear to premieres. Most of the time, it’s a snooze fest. Black suit, white shirt, maybe a funky tie if they’re feeling “crazy.”
Fionn O’Shea? The guy takes risks.
Scroll through his Instagram or look at the red carpet photos from the Normal People press tour. He plays with silhouette. He wears textures. He isn’t afraid of a bit of color.
To me, this says a lot about his confidence. It takes guts to wear something unconventional when you know the Daily Mail is waiting to roast you. It mirrors his acting choices. He is willing to look different. He is willing to stand out.
But he balances this with a relatively private life. You don’t see him falling out of nightclubs at 3 AM. You don’t see him starting Twitter beefs with random trolls. He keeps the mystery alive. In a world where we know what our favorite celebrities ate for breakfast, that reticence is refreshing. It allows us to look at him on screen and see the character, not the guy we saw on TikTok five minutes ago.
How did Cherry prove he could handle Hollywood scale?
The transition from Irish indie films to American blockbusters is where a lot of actors stumble. The sets are bigger, the pressure is higher, and the craft service table alone probably costs more than the budget of Handsome Devil.
O’Shea made the leap with Cherry. Directed by the Russo Brothers (the guys who made Avengers: Endgame), starring Tom Holland. This was the big leagues.
O’Shea played Arnold. It wasn’t the lead role, but it was a significant one. And he had to do it with an American accent.
Now, I’m critical of accents. Nothing ruins a movie faster than a dodgy American drawl from a European actor. But O’Shea pulled it off. If I didn’t know he was from Dublin, I wouldn’t have clocked him.
The movie itself got mixed reviews—it was heavy, chaotic, and stylized—but O’Shea survived the machine. He proved he could stand next to Spider-Man and hold his own. It showed casting directors that he was viable for the big US productions. It was a strategic move, broadening his marketability without selling his soul.
What was the deal with Wolf?
Okay, we have to talk about Wolf. This movie is weird. Wonderfully, unapologetically weird. It’s about a clinic for people who suffer from species dysphoria—they believe they are animals trapped in human bodies.
O’Shea plays Rufus, who believes he is a German Shepherd.
I remember watching the trailer and thinking, “This is either going to be a disaster or a masterpiece.” It ended up being a fascinating art-house experiment.
Why does this matter for O’Shea? Because it shows his appetite for the bizarre. He could have played the romantic lead in a Hallmark movie and cashed a check. Instead, he chose to crawl around on all fours and bark.
That is bravery. That is an actor who is chasing the craft, not the fame. He committed to the physicality of the role. He didn’t wink at the audience. He played the absurdity with a straight face, which is the only way that kind of movie works. It reminded me of the daring choices actors like Daniel Day-Lewis or Joaquin Phoenix make. He is willing to look foolish in service of the art.
How does he maintain such strong industry friendships?
There is this pervasive myth that actors are all secretly jealous of each other. That they are clawing each other’s eyes out for roles. But looking at O’Shea’s circle, you see the opposite.
He and Paul Mescal are genuinely close friends. They lived together. They travel together. There are photos of them at Glastonbury, just two lads in a field, enjoying the music.
I love this dynamic. It breaks the “rivalry” narrative. It must be surreal to go through the explosion of fame at the same time as your best friend. They can ground each other. When the world is screaming your name, you need someone who knew you when you were broke and auditioning for commercials to tell you to shut up and pass the remote.
This grounding shows in his work. He doesn’t have that frantic, desperate energy of someone who is alone in the spotlight. He seems supported. He seems safe. And a safe actor is a bold actor.
What is next for the man who can play anything?
So, where do we go from here? Fionn O’Shea is in his mid-20s. He has decades ahead of him.
He recently starred in Dance First, the Samuel Beckett biopic, alongside Gabriel Byrne. This feels like a natural progression. He has that literary, intellectual look that fits a young Beckett perfectly.
But I want to see him stretch even further.
- The Action Heel: I want to see him play a Hans Gruber-type villain in a big action movie. He has the intelligence and the menace for it.
- The Romantic Lead: Let’s see him get the girl (or the guy) for once without a tragic ending. He has a charm that hasn’t been fully utilized yet.
- Dark Comedy: Give him something like Succession. He would fit right into that world of sharp tongues and broken morals.
The trajectory is pointing straight up. He hasn’t peaked. He is just warming up.
Why does his acting feel so much more visceral than his peers?
I’ve been trying to pin this down. Why does O’Shea stick in my brain when other actors fade?
I think it’s the eyes. He has very expressive eyes. In Normal People, his eyes were dead. Cold. Calculating. In Handsome Devil, they were wide, fearful, and hopeful. In Dating Amber, they were panicked.
He does a lot of work without saying a word. He understands that acting is reacting. It’s listening.
I watched an interview with him once where he talked about “finding the truth” in a scene. It sounded like standard actor-speak at first, but then I watched him again. He doesn’t rush. He lets the awkward silences sit. He lets the discomfort linger. That willingness to sit in the uncomfortable moments is what makes him feel human. Real humans are awkward. We pause. We stumble. O’Shea captures that rhythm of life perfectly.
Is he the voice of a confused generation?
Look at the roles: A bullied outcast, a closeted teen, an abusive boyfriend, a German Shepherd.
Okay, maybe not the German Shepherd. But the others? They all speak to a generation that is trying to figure out who they are.
Millennials and Gen Z are obsessed with identity. Who are we? What do we want? O’Shea chooses projects that ask these questions. Handsome Devil asks, “Do I have to choose between being a man and being an artist?” Normal People asks, “Why do we hurt the people we love?”
He isn’t just entertaining us; he is reflecting us.
I have a younger cousin who struggled with his sexuality in high school. He told me that watching Handsome Devil was the first time he felt like someone “got it.” He said Ned Roche made him feel brave.
That is the power of what O’Shea is doing. It’s not just content. It’s connection.
Final Thoughts: The Long Game
Fionn O’Shea isn’t a firework. Fireworks are loud, bright, and then they leave smoke and darkness. He is a slow burn. He is a hearth fire.
He has built a career brick by brick, role by role. He hasn’t skipped steps. He hasn’t relied on scandals or tabloids to keep his name in the press. He has relied on the work.
From the rain-soaked rugby pitches of Handsome Devil to the sun-drenched, toxic villas of Normal People, he has proven that he can do it all. He can make you love him. He can make you hate him. He can make you laugh until your sides hurt.
I’ll be honest: I still haven’t totally forgiven Jamie. That character traumatized me. But that grudge I hold? It’s basically a love letter to Fionn O’Shea’s talent.
If you haven’t done a deep dive into his filmography, do it this weekend. Start with Handsome Devil. Move to Dating Amber for a palette cleanser. Then, if you’re feeling emotionally stable, tackle Normal People.
Just maybe keep the remote control out of throwing distance when Jamie walks on screen. Trust me on that one.
