Prime Video has officially unveiled the teaser trailer, teaser art, and premiere date for Young Sherlock, a bold new reimagining of the world’s most iconic detective. Directed and executive produced by Guy Ritchie, the eight-episode series stars Hero Fiennes Tiffin as a younger, rawer version of Sherlock Holmes. The show is set to premiere globally on March 4, 2026, streaming exclusively on Prime Video across more than 240 countries and territories.
An Origin Story Set Before Baker Street
Young Sherlock explores the formative years of Sherlock Holmes long before he becomes the legendary detective of Baker Street. Set primarily in 1870s Oxford, the series introduces Holmes as a disgraced, volatile young man whose razor-sharp intellect is still untamed. When he becomes entangled in a murder case that threatens his freedom, Sherlock is forced into his first true investigation.
What begins as a desperate fight for survival soon expands into a far-reaching conspiracy, reshaping his understanding of logic, justice, and power. True to Guy Ritchie’s signature style, the series blends sharp wit, kinetic action, and irreverent storytelling, presenting Sherlock not as a finished icon but as a restless and anarchic young mind still discovering his identity.
Guy Ritchie Reinvents a Literary Legend
With Young Sherlock, Guy Ritchie brings the energetic flair that defined his earlier Sherlock Holmes films, but grounds it in a darker, character-driven origin story. The series leans into the chaos, impulsiveness, and raw intelligence of a young man yet to be shaped by discipline or reputation.
Rather than reverence, the show embraces reinvention, portraying Sherlock as someone forged by danger, mistakes, and moral ambiguity. Ritchie directs the first two episodes and serves as executive producer, setting the tone and visual language from the very beginning.
A Strong Ensemble Cast Elevates the Narrative
Alongside Hero Fiennes Tiffin, Young Sherlock boasts an impressive supporting cast including Dónal Finn, Zine Tseng, Joseph Fiennes, Natascha McElhone, Max Irons, and Colin Firth. Each character plays a pivotal role in shaping Sherlock’s journey, challenging his beliefs, and complicating his path toward becoming a detective.
The ensemble ensures the series extends beyond a single character study, creating a richly layered world filled with intellectual rivals, moral counterpoints, and shadowy authority figures.
Creative Minds Behind the Series
The series is created for television by Matthew Parkhill, who also serves as showrunner and executive producer. He is joined by executive producers Dhana Rivera Gilbert, Marc Resteghini, Simon Maxwell, Ivan Atkinson, Simon Kelton, and Colin Wilson, with Harriet Creelman and Steve Thompson serving as co-executive producers. Physical production is led by Motive Pictures, ensuring cinematic scale and period authenticity.
When and Where to Watch
All eight episodes of Young Sherlock will premiere on March 4, 2026, exclusively on Prime Video. With its mix of historical intrigue, psychological depth, and Guy Ritchie’s trademark kinetic storytelling, the series promises to introduce Sherlock Holmes to a new generation — before the legend was fully formed.
