Cillian Murphy’s acting career is a spectrum painted with vivid contrasts. He has morphed effortlessly from the cold precision of a physicist to the shadowy depths of a supervillain, into the gritty textures of a gangster. His roles, electric with intensity, often sparked cinematic blasts, leaving audiences captivated. Yet, in his latest venture, the nuclear flare has been dimmed, and contemplation aglow. The nuclear actor prepares to embrace nuanced humanity rather than explosive personas, peeling back the layers to reveal quieter, but no less atomic, stories.

When the atom splits, sometimes the quietest particles hold the most charge. 

Cillian Murphy’s fresh role in Toronto International Film Festival line-upper Steve, as a headteacher of a reform school, marks a thoughtful detour. In this film, based on Max Porter’s novella 'Shy', Murphy embodies a man at the heart of systemic pressure, fighting to preserve his school from closure. The character wrestles with his own fragile mental health while battling external challenges. Steve is no larger-than-life figure but a human caught in the whirlwind of responsibility and personal vulnerability. It is a shift from Murphy’s usual high-voltage energies to something softer yet equally magnetic.

The source material, 'Shy', is Porter's acclaimed 2023 novella, reimagined for the screen with a screenplay by Porter himself. Set in the mid-1990s, Steve unfolds over the course of one crucial day at the reform school. Alongside Murphy, who is also set to star in a Daniel Craig number, the cast includes Jay Lycurgo as Shy, a troubled student; Tracey Ullman; Simbi Ajikawo; and Emily Watson, who reunites with Murphy after Small Things Like These. The film is also set to drop on Netflix on October 3, 2025, after a limited theatrical run beginning September at TIFF.

A fortress of feels rises where school walls stand tall—Murphy, Mielants, and Porter team up to champion the quiet heroes battling the system every day

Director Tim Mielants, who also collaborated previously with Cillian Murphy on Small Things Like These, brings this intimate drama to life for Netflix, marking Murphy’s first original movie with the streaming giant. The film combines poignant storytelling with complex character study, offering a searing look at societal neglect through Steve’s battle to keep the school, a last-chance refuge for marginalized boys, alive. The musical score by Ben Salisbury and Geoff Barrow enhances the film’s emotional gravity, weaving a rich landscape against which these personal and institutional struggles unfold.

Steve stands as a powerful emblem of Cillian Murphy’s evolving artistry, balancing intensity with introspection. His portrayal is less about loud explosions and more about the quiet battles faced behind closed doors, illuminating the human stories often lost in the shadows. As the film premieres at the Toronto International Film Festival’s Platform section, it promises to be a reminder of how the most compelling stories are those fought in hushed tones and small moments of resilience.
