Guy Ritchie’s Young Sherlock Arrives on Prime Video March 2026 — The Origin Story You Can’t Miss
Young Sherlock lands on Amazon Prime Video in March 2026, following a razor-sharp Holmes through his college years before the legend begins.
Guy Ritchie is back in Baker Street territory, but this time he is starting at the beginning. Young Sherlock is an 8-episode mystery series hitting Prime Video in March, with Ritchie directing every single episode. It is built to echo the swagger of his billion-dollar Sherlock Holmes movies, even though this show pulls from a different shelf: Andrew Lane's Young Sherlock Holmes novels, not Conan Doyle's originals.
So what is Young Sherlock?
Set roughly 17 years after Ritchie's first Sherlock Holmes (2009) and 15 after A Game of Shadows (2011), this is a coming-of-age spin that zeroes in on Sherlock's college years at Oxford. Hero Fiennes-Tiffin plays a rebellious 19-year-old Holmes getting pulled into his very first big case: an unsolved murder. With Ritchie steering all eight episodes, expect stylistic fingerprints that line up with the Downey/Law films, even as the story takes its cues from Lane's youth-focused books.
All eight episodes debut on Prime Video on March 4, 2026. Ritchie is essentially retooling the formula that hauled in $1.1 billion at the box office, only now the spotlight is on a raw, not-yet-fully-formed investigator learning the trade in real time.
No Watson, more Holmes family drama
Watson sits this one out, which opens the door for a different dynamic: Sherlock's family. The show tracks his push-pull with his father Silas Holmes (played by Joseph Fiennes), his mother Cordelia (Natascha McElhone), and his older brother Mycroft (Max Irons). Fun wrinkle: Joseph Fiennes is Hero Fiennes-Tiffin's real-life uncle, which gives those father-son scenes an extra charge.
New faces at Oxford (and one very familiar nemesis)
- Hero Fiennes-Tiffin as Sherlock Holmes, 19
- Joseph Fiennes as Silas Holmes (Sherlock's father)
- Natascha McElhone as Cordelia Holmes (Sherlock's mother)
- Max Irons as Mycroft Holmes
- Colin Firth as Sir Bucephalus Hodge
- Zine Tseng as Princess Gulun Shou'an, a Chinese classmate
- Donal Finn as James Moriarty
- Simon Delaney as Detective Fitget
- Adam James as Dr. Charles Maltby
- Rachel Shelley as Mrs. Anna Tilcott
Yes, Moriarty turns up early in Sherlock's life here, and he is not treated like a background tease. Oxford, meanwhile, is packed with new allies, rivals, and authority figures rubbing up against a young man who is already too sharp for the room.
Ritchie, the receipts, and why this has heat
Ritchie has the Holmes track record: $524 million worldwide for Sherlock Holmes in 2009, $544 million for A Game of Shadows in 2011. More recently, he has leaned into TV with strong results on The Gentleman and MobLand, and he has been busy behind the scenes as an executive producer on The Diamond Heist. Handing him all eight episodes suggests a unified tone and pace rather than a patchwork season.
Meanwhile, on the film side...
There is movement again on Sherlock Holmes 3. As of January 30, 2026, the project was back in development. The last known setup had Dexter Fletcher (Rocketman) in the director's chair, with Robert Downey Jr. and Jude Law expected to return.
Bottom line: the big-screen future may still be sorting itself out, but Ritchie is definitively back in the Holmes sandbox right now. Young Sherlock looks like a lean, first-case origin story with family friction, an Oxford backdrop, and Moriarty lurking from day one. All episodes land March 4, 2026 on Prime Video.
