Cillian Murphy is garnering significant attention for his role in the upcoming film "Steve," where he plays the headteacher of a reform school for boys with societal and behavioral difficulties. The film, directed by Tim Mielants, is based on Max Porter's novella "Shy". "Steve" had its world premiere at the 2025 Toronto International Film Festival and is scheduled for a limited theatrical release on September 19, 2025, followed by its debut on Netflix on October 3, 2025.

In "Steve," Murphy portrays Steve, a dedicated but troubled headteacher at Stanton Wood, a residential reform school for delinquent teenage boys in the mid-90s. The film unfolds over a single, harrowing day as a local television crew arrives to film a segment about the school, coinciding with news that the school may be closed. Steve grapples with his mental health while fighting to protect the school's integrity and impending closure. The film also explores the relationship between Steve and Shy, a troubled student.

Murphy's portrayal of Steve has been lauded by critics, with some noting that the film wouldn't work as well with a lesser actor in the central role. He brings subtlety and grace to the character, showcasing the character's intense focus and the weight of his responsibilities. Critics highlight Murphy's ability to convey both the character's dedication to his students and his internal struggles.

Murphy himself has spoken about his newfound respect for teachers. He noted that his parents and grandfather were teachers, making education "very much part of who I was as a young person". He recognizes the immense undertaking of teachers, calling them "custodians of the next generation" and praising them for "holding our society together". Despite his admiration, Murphy joked that he would be a "terrible" teacher, lacking the confidence to lead a real classroom.

To prepare for the role, Murphy adopted a different approach than his usual method of extensive research and isolation. Instead, he chose to be more spontaneous and responsive to the unfolding events during filming, aiming to capture the unpredictable nature of Steve's daily life and the stress he experiences.

"Steve" also stars Tracey Ullman, Jay Lycurgo, Simbi Ajikawo, and Emily Watson. The film marks another collaboration between Murphy and director Tim Mielants, who previously worked together on "Peaky Blinders" and "Small Things Like These".

Beyond "Steve," Cillian Murphy has several other projects in the pipeline. He will reprise his iconic role as Tommy Shelby in "The Immortal Man," a film continuation of the "Peaky Blinders" series. He is also involved in two sequels to "28 Days Later," titled "28 Years Later" and "28 Years Later: The Bone Temple," serving as both an actor and executive producer. Additionally, he is set to star in and produce "Blood Runs Coal," a true crime drama about the Yablonski Murders.
