First Look at Guy Ritchie's Young Sherlock for Prime Video

Prime Video has released the first footage of Young Sherlock, a new series starring Hero Fiennes Tiffin as the young Sherlock Holmes.Young Sherlock, from Guy Ritchie, presents a reinterpretation of the early years of Sir Arthur Conan Doyle's iconic detective. Set in the 1870s, the story follows a young Sherlock Holmes who is far from the composed, brilliant sleuth he will later become known for. Instead, we see him as a disgraced, rough, and uninhibited young man.

When Holmes unexpectedly becomes entangled in a murder case that threatens his freedom, he faces his very first major investigation. What begins as a personal struggle quickly escalates into an international conspiracy that will change his life forever.

The series is partly set in Oxford but also takes Sherlock to foreign locations, adding to the adventurous nature of the story. Along the way, the early antics, anarchistic behavior, and sharp mind of the adolescent are revealed, long before he becomes the legendary resident of Baker Street. This origin story shows how his experiences and choices lay the foundation for the detective he will later become.

In addition to Hero Fiennes Tiffin, the cast includes Dónal Finn, Zine Tseng, Joseph Fiennes, Natascha McElhone, Max Irons, and Colin Firth, providing the series with a strong ensemble cast.

Guy Ritchie not only directs but also serves as an executive producer.

With this combination of a well-known literary figure, a fresh perspective, and a prominent creative team, Prime Video is betting on a grandly staged, adventurous origin story that sheds new light on one of history's most iconic detectives.

Young Sherlock premieres in 2026 on Prime Video.
