Major British TV Series to Watch for in 2026

Below, we explore some of the most anticipated upcoming British TV series for 2026, highlighting their themes, cast, storylines, and what makes each one stand out.

The BBC’s Reimagining of a Literary Classic: A Tale of Two Cities

A Fresh Take on Dickens’ Masterpiece

The BBC is preparing to bring Charles Dickens’ iconic novel to screens in a new format that promises to be both faithful and inventive. While there have been several adaptations of “A Tale of Two Cities” over the years, none have featured Kit Harington in the role of Charles Darnay. This inclusion is generating buzz among fans eager to see Harington step into a period drama after his notable work in “Game of Thrones.”

The series will consist of four episodes that delve into the tumultuous period of the French Revolution, focusing on the lives of individuals caught between loyalty, love, and political upheaval. Kit Harington’s portrayal of Charles Darnay, a French aristocrat trying to navigate a treacherous landscape, is expected to be both nuanced and compelling. He finds himself tried for treason in England, a trial that hinges on the appearance of Sydney Carton (played by François Civil), a lawyer whose resemblance to Darnay becomes pivotal in the story.

The plot thickens when Darnay is re-arrested during the Revolution and faces execution. Sydney Carton, who has a complex history with Darnay’s wife, Lucie (Mirren Mack), faces a moral dilemma that could change everything. The series aims to explore themes of sacrifice, redemption, and the human cost of political chaos, all set against the vivid backdrop of revolutionary France and England.

Why This Series Matters

This adaptation is set to stand out for its contemporary approach to a classic story. By focusing on the emotional depth of each character and the moral conflicts they face, the series aims to resonate with modern audiences. The casting, especially Harington’s involvement, suggests a strong focus on character-driven storytelling. The series will also utilize modern filmmaking techniques to bring the period setting to life with authenticity and visual flair.

Under Salt Marsh: A Coastal Mystery on Sky Atlantic

A Storm Brings Hidden Secrets to the Surface

On Sky Atlantic, a new series titled “Under Salt Marsh” is poised to become a must-watch in 2026. The story revolves around Jackie Ellis (Kelly Reilly), a former detective turned teacher, who faces a chilling discovery amid an approaching storm. When she finds the body of Cefin, an eight-year-old student, her world begins to unravel.

Cefin’s death appears to be an accidental drowning, but the timing and circumstances raise suspicions. The incident reignites a case from three years earlier—the disappearance of Jackie’s niece, Nessa. That unresolved case had devastating consequences for Jackie’s career, casting a shadow over her life ever since.

As the storm looms closer, Jackie teams up with her former partner, Detective Eric Bull (Rafe Spall). Together, they suspect that Cefin’s death and the earlier disappearance are linked, hinting at buried secrets that could threaten to destroy lives if exposed. The series promises to blend elements of suspense, emotional depth, and atmospheric tension, capturing the essence of small-town dramas where everyone has something to hide.

Themes and Expectations

“Under Salt Marsh” aims to explore themes of grief, guilt, and the lengths people will go to protect their loved ones. The setting—a coastal town buffeted by storms—serves as a metaphor for the turbulent emotional landscape of the characters. With strong performances and a gripping storyline, the series is expected to attract viewers who appreciate slow-burning mysteries with layers of complexity.
