Sheridan Smith’s new series for 2026 is “The Cage,” a high-stakes heist thriller produced for BBC One and BBC iPlayer. Written by The Responder creator Tony Schumacher and set in a Liverpool casino, the five-part series stars Smith as Leanne, a casino worker who discovers her colleague Matty (played by Michael Socha) is also plotting to rob their employer. This discovery triggers a collision course with local gangsters and the police, blending crime, family drama, and dark humor.
While “The Cage” is her primary television project currently in production, Smith has also recently dominated headlines with the 2025 ITV series “I Fought the Law,” where she portrayed real-life campaigner Ann Ming. Additionally, she is currently starring in the 2026 West End revival of Alan Ayckbourn’s psychological drama “Woman in Mind” alongside Romesh Ranganathan. This guide provides a deep dive into her upcoming roles, recent hits, and what fans can expect from the “Queen of Drama” in the coming year.
Everything About “The Cage” (2026)
The Cage is Sheridan Smith’s latest collaboration with the BBC, marking a shift toward the “heist thriller” genre. Set within the glittering but gritty world of an inner-city Liverpool casino, the show follows two “ordinary” people pushed to extraordinary lengths.
Filming for the series took place across Liverpool and the Wirral in early 2025, with a scheduled release window of mid-to-late 2026. Fans can expect a “Tony Schumacher special”—meaning the script will likely be raw, authentic, and deeply rooted in the Northern English experience.
Plot and Character Dynamics
Smith plays Leanne, a character described as “relatable and full of heart,” who is struggling with the financial pressures of modern life. When she realizes her co-worker Matty (Michael Socha) has the same illegal intentions as her, the pair form an unlikely and dangerous alliance.
The series is not a traditional “glamorous” heist; instead, it focuses on the desperation and moral dilemmas of the characters. Producers have teased that the show is as much a “love story of sorts” as it is a crime drama, exploring themes of loyalty and family survival.
“I Fought the Law” (ITV Release)
Airing in late 2025, I Fought the Law saw Sheridan Smith take on the role of Ann Ming, the mother who spent 15 years fighting to overturn the UK’s 800-year-old “Double Jeopardy” law. The four-part drama was based on the true story of the murder of Ann’s daughter, Julie Hogg, in 1989.
The series was highly acclaimed for Smith’s transformative performance, capturing the relentless grief and steely determination of a mother who refused to take “no” for an answer. It served as a landmark piece of social-justice television, highlighting how one woman changed the British legal system forever.
Sheridan Smith in “Woman in Mind”
In early 2026, Smith made a triumphant return to the stage in a revival of Alan Ayckbourn’s Woman in Mind at the Duke of York’s Theatre in London. The play is a darkly comic exploration of mental health, following a woman whose world splits into a mundane reality and a vibrant, imagined fantasy after a head injury.
The production, which also stars comedian Romesh Ranganathan in his professional stage debut, has been a massive box-office success. After its London run, the play toured to Sunderland and Glasgow in March 2026, receiving five-star reviews for Smith’s “hypnotic” and “unmissable” performance as Susan.
“The Castaways” Success and Legacy
Fans of Smith’s more adventurous work recently enjoyed her leading role in The Castaways, which aired on Channel 5 in early 2025 after a Paramount+ debut. Smith played Lori, a woman whose plane crashes on a remote island, leaving her sister Erin (Celine Buckens) to investigate a dark conspiracy.
The series was notable for its physical demands, with Smith famously revealing that she had to “conquer her fear of water” to film the intense shipwreck scenes. While a second season has not been officially confirmed, the show remains a top-tier recommendation for those seeking a “Lost-style” suspense thriller.
