Every generation gets the antihero it deserves. The one Maciej Musiałowski played in Jan Komasa’s The Hater was not a cartoon monster but something more unsettling: a young man smart enough to understand the machinery of social media toxicity and emotionally hollow enough to use it without hesitation. That portrayal — meticulous, unrepentant, genuinely frightening — came from a twenty-six-year-old with only a handful of TV credits and a head full of ideas about what performance could do. The role landed Musiałowski the Best Actor prize at the Polish Film Festival in Gdynia in 2020. It also earned the film a distinction at Tribeca. Two different countries, two different juries, the same uncomfortable recognition: that this actor had found something real in Tomasz Giemza, something that went beyond the mechanics of genre.

He grew up in Warsaw, in a city still negotiating its relationship with everything that came before and after 1989, and found his way to performance young enough that it felt less like a career choice and more like a natural habitat. He trained at the Leon Schiller National Film, Television and Theatre School in Łódź — Poland’s most rigorous conservatoire for screen performance — and graduated in 2018. Before that, his early abilities had already attracted the attention of the Ministry of Culture and National Heritage, which awarded him a scholarship for outstanding achievements, and he won Grand Prix at the Actor Song Review in Wrocław in 2015, a competition that has served as a testing ground for Polish talent for decades. He was born on December 5, 1993.

The first time most Polish audiences encountered Musiałowski was in the TV series Druga szansa, starting in 2016, where he played Ksawery Kryński. The performance was strong enough to earn him a Telekamery nomination in the TV Hope category the following year — the Polish television industry’s way of saying: this is someone to watch. The problem with being someone to watch at twenty-three is that you spend the next several years having people watch you, often waiting for you to repeat exactly what you did before.

What made The Hater more than a genre exercise was Musiałowski’s refusal to cast Tomasz Giemza as simply malevolent. This is a man shaped by social resentment, by exclusion, by the specific injury of feeling permanently adjacent to the world he wants to inhabit. The film’s real subject is not trolling but aspiration rotted by humiliation, and Musiałowski played it with the kind of precision that made audiences uncomfortable because Giemza’s logic is never entirely opaque. That degree of empathy-without-endorsement is technically difficult and rarely attempted by actors at the beginning of their careers. Director Jan Komasa and Musiałowski worked together to locate the exact moment at which recognizable grievance tips into something irreversible — and held it there, under sustained pressure, for the duration of the film. The Eagle Award nomination that followed acknowledged what the Gdynia jury had already confirmed.

The years after The Hater tell the story of an actor refusing the obvious sequel. Musiałowski appeared in the television crime drama Krew in 2023, playing Kacper Dąbrowa across five episodes — a character diametrically opposed to Giemza in his emotional transparency. He also appeared in Freestyle the same year, a film centred on breakdance culture in contemporary Poland, as Diego. When the comedy panel show LOL: Last One Laughing Poland invited him as a contestant, he accepted. It was the kind of move that conventional career logic would have advised against — too casual, too likely to dilute whatever serious-actor authority he had accumulated — and it made his range visible in the most direct way possible. The same instinct showed in Chrzciny in 2022, a film that earned him a Zbyszko Cybulski Award nomination, one of Poland’s most significant honours for young screen actors.

There has also been music. His 2021 single with Julia Wieniawa, Zabierz tę miłość, achieved platinum certification in Poland — a distinction usually reserved for pop acts with far more infrastructure behind them. The single is more curiosity than pivot, but the fact that Musiałowski chose to record it signals something about how he approaches creative adjacency: as exploration rather than strategy. In 2024 he participated in Poland’s national Eurovision selection with the song “Daj mi jakiś znak,” placing ninth in the internal eliminations — a footnote in the career chronology, but one that further complicates any simple reading of who this actor is outside his screen work.

The project that now defines Musiałowski’s immediate horizon is Lalka, the 2026 film adaptation of Bolesław Prus’s nineteenth-century novel, one of the canonical works of Polish literature — a story set in 1870s Warsaw that anatomises social ambition and class aspiration with the kind of clinical precision that has kept it relevant for over a century. Musiałowski plays Maruszewicz, a significant presence in the social world the film inhabits. The distance between a character who weaponizes social media and one who navigates the drawing-room politics of 1870s Warsaw is exactly the kind of distance that separates an actor from a persona. He also appeared in Chcę więcej, released in January 2026, extending a filmography that now spans social thriller, crime drama, literary comedy, and period adaptation.

Polish cinema is in a period of unusual international visibility — The Hater‘s international attention was a signal, not an anomaly — and Musiałowski is among the actors on whom that attention has settled. What he does with Lalka, and whatever comes after it, will clarify whether his career is building toward a singular thing or whether the whole point is that it is not.
