Young Sherlock (Prime Video): Guy Ritchie Reinvents Sherlock Holmes in a Bold Origin Story

“Stay out of trouble? We’ll see about that.”

The world’s most famous detective is getting a radical new beginning. Young Sherlock, Guy Ritchie’s explosive reimagining of Sherlock Holmes’ early years, is officially coming to Prime Video on March 4, 2026 — and the newly released teaser confirms one thing loud and clear: this is not the Sherlock you think you know.

Set decades before Baker Street, Young Sherlock transforms the legendary sleuth into a raw, reckless, brilliant young man whose very first case threatens to destroy him — or forge him into a legend.

The game isn’t just afoot.

It’s being rewritten.

Young Sherlock Release Date & Where to Watch

• Series Title: Young Sherlock

• Streaming Platform: Amazon Prime Video

• Global Release Date: March 4, 2026

• Availability: Streaming in 240+ countries and territories

This is one of Prime Video’s biggest global series launches of 2026.

What Is Young Sherlock About?

Before the pipe.Before the coat.Before the legend.

Young Sherlock follows 19-year-old Sherlock Holmes at Oxford University in the 1870s, long before he becomes the calculating mastermind of Baker Street.

Disgraced, impulsive, and dangerously intelligent, Sherlock is dragged into a murder investigation that puts his own freedom at risk. What begins as a desperate attempt to clear his name spirals into a globe-trotting conspiracy, exposing secret societies, political power plays, and enemies who will define his future.

This first case doesn’t just solve a crime —it creates Sherlock Holmes.

Guy Ritchie’s Sherlock Universe Returns — Louder and Faster

Director Guy Ritchie brings back the kinetic energy, swagger, and sharp wit that defined his Sherlock Holmes films — but with a younger, more volatile protagonist.

Expect:

• Fast-paced action

• Stylish period visuals

• Brutal hand-to-hand combat

• A rebellious Sherlock who breaks rules before he invents them

This is origin storytelling with attitude.

Hero Fiennes Tiffin as Young Sherlock Holmes

Best known for the After franchise, Hero Fiennes Tiffin steps into one of fiction’s most iconic roles — and it’s a bold casting choice that signals change.

This Sherlock is:

• Arrogant but untrained

• Brilliant but emotionally reckless

• More fighter than thinker — for now

He hasn’t mastered deduction yet.

He hasn’t learned restraint.

And that’s what makes him dangerous.

Young Sherlock Cast: Stacked and Strategic

Prime Video isn’t playing small with this ensemble.

Main Cast

• Hero Fiennes Tiffin as Sherlock Holmes

• Joseph Fiennes as Silas Holmes (Sherlock’s adventurous father)

• Natascha McElhone as Cordelia Holmes (Sherlock’s artistic mother)

• Max Irons as Mycroft Holmes

• Colin Firth as Sir Bucephalus Hodge

Breakout & International Roles

• Zine Tseng as Princess Gulun Shou’an — scholar, martial artist, and key ally

• Dónal Finn as James Moriarty — yes, that Moriarty

• Numan Acar, Ravi Aujla, Rachel Shelley, Adam James, and more

The inclusion of Moriarty this early signals a long-term storytelling plan — and a rivalry that begins far sooner than fans expect.

Based on the Young Sherlock Holmes Novels

The series adapts Andrew Lane’s Young Sherlock Holmes book series, itself inspired by Sir Arthur Conan Doyle’s original work.

But this is not a faithful, polite adaptation.

Guy Ritchie’s Young Sherlock is:

• Louder

• Darker

• More action-driven

• Less myth, more blood and consequence

It respects the character — not the rules.

Why Young Sherlock Could Be Prime Video’s Next Global Hit

🧠 A Fresh Entry Point

No homework required. This is Sherlock for a new generation.

🔥 Guy Ritchie’s Signature Style

Fast dialogue. Brutal action. Stylish chaos.

🌍 Global Stakes

Oxford is just the beginning — the story expands far beyond England.

🧩 Moriarty’s Early Introduction

A long-game rivalry from the very start.

How Young Sherlock Is Different From Other Sherlock Adaptations

This is not:

• BBC’s controlled, cerebral Sherlock

• Elementary’s modern procedural

• Classic Victorian comfort

This is Sherlock before discipline — a genius who hasn’t yet learned the cost of being right.

Mistakes matter here.

Consequences linger.

And survival isn’t guaranteed.

What the Teaser Confirms (Without Spoilers)

• Sherlock is already feared — not respected

• Violence is part of his learning curve

• His moral code is still forming

• His enemies are smarter than he expects

Every choice pushes him closer to becoming the man history remembers.

Final Verdict: Sherlock Begins Again

Young Sherlock isn’t just an origin story — it’s a controlled detonation of everything we think we know about Sherlock Holmes.

With Guy Ritchie at the helm, Hero Fiennes Tiffin redefining the role, and Prime Video backing it globally, this series has all the ingredients to become one of 2026’s most talked-about shows.

Before Baker Street.Before Watson.Before the legend.

This is where Sherlock Holmes is forged.
