The game is officially afoot for a new generation. Prime Video launched all eight episodes of Young Sherlock today, March 4, 2026, bringing Guy Ritchie’s high-octane vision of the legendary detective to screens worldwide. Starring Hero Fiennes Tiffin as a 19-year-old Sherlock Holmes, the series strips away the deerstalker hat to reveal a disgraced genius navigating his first murder case while a student at Oxford University.

Produced by Amazon MGM Studios, the series features a powerhouse supporting cast that keeps the drama all in the family. Joseph Fiennes stars as the detective’s father, Silas Holmes, while Oscar-winner Colin Firth joins the fray as Sir Bucephalus Hodge. The show, written by showrunner Matthew Parkhill, is inspired by Andy Lane’s popular book series and focuses on the formative events that shaped the world's most famous consulting detective.

Early buzz following global premiere events in London and New York has been electric. Fans are already praising the chemistry between Tiffin and the cast, which also includes Zine Tseng as Princess Gulun Shou'an and Natascha McElhone as Cordelia Holmes. With Ritchie’s signature fast-paced directing style and a gritty 19th-century setting, the series is already generating a massive social media response as viewers dive into the full-season binge.
