I keep thinking about the way the wind sounds in Black Island—not the wind itself, but the way the film lets you hear it. It’s there in the background, a low, constant howl, like the North Sea is breathing through the walls of every scene. That sound does more work than any line of dialogue in this quiet, unsettling thriller.
It’s the kind of detail that makes you lean in, even when you’re not entirely sure what you’re leaning toward.
Miguel Alexandre’s film is set on a remote German island, a place where the landscape feels like a character in its own right. The island isn’t just a backdrop; it’s a pressure cooker, a place where secrets fester because there’s nowhere to hide. The story follows Jonas (Philip Froissant), a teenage boy sent to live with his grandfather after the death of his parents.
He’s adrift, emotionally and literally—an orphan in a place that doesn’t seem to want him. Then Helena (Alice Dwyer), a new teacher, arrives at his school, and something shifts. She’s magnetic, enigmatic, the kind of person who seems to exist just outside the rules of the world Jonas knows.
Their relationship is the film’s engine, but it’s not a love story. It’s something far more dangerous.
The first time we see Helena, she’s standing in front of a classroom, her back to the camera. The students are restless, but she doesn’t turn around. She just starts talking, her voice low and measured, as if she’s already decided they’re going to listen.
It’s a small moment, but it’s electric. Alice Dwyer plays her with a stillness that’s unsettling—like she’s always holding something back. There’s a scene early on where she and Jonas are alone in a classroom, and she asks him about his parents.
The camera lingers on her face, and you can see the calculation in her eyes. She’s not just making conversation; she’s testing him. Dwyer makes that ambiguity feel deliberate, like Helena is always two steps ahead of everyone else.

Public reportsNetflix’s Black Island (2021): A German Thriller with Dark Secrets and Behind-the-Scenes Intrigue
Black Island (Schwarze Insel), the 2021 German thriller directed by Miguel Alexandre, arrived on Netflix with a premise as chilling as its title: a young man sent to a remote island to live with his grandfather uncovers sinister family secrets. Starring Philip Froissant and a cast of veteran German actors, the film blends mystery, suspense, and psychological tension—though its reception has been as divided as its plot twists. latestnetflix.com's view is that here’s what we know about the movie’s creation, its polarizing ending, and the buzz surrounding its release.
A Portuguese Director’s Foray into German Thriller Territory
Miguel Alexandre, the film’s director, is better known for his work on Portuguese telenovelas and dramatic television series 
. Black Island marked a departure from his usual genre, venturing into the thriller space with a distinctly German setting. The shift raised eyebrows among fans of his earlier work, but Alexandre’s background in character-driven drama may explain the film’s focus on psychological depth over outright horror.
The movie’s original title, Schwarze Insel, hints at its German roots, though its Netflix release under the English name Black Island broadened its appeal. The 104-minute runtime suggests a tight, suspenseful narrative, but whether Alexandre’s telenovela experience translated well into thriller pacing remains a point of debate among critics.
