Young Sherlock

description

Young Sherlock is a Prime Video mystery-adventure series created by Matthew Parkhill, with Guy Ritchie directing the opening episodes and executive producing. A stylish origin story for Arthur Conan Doyle's detective, it reimagines Holmes as a nineteen-year-old and carries Ritchie's signature kinetic flair.

Hero Fiennes Tiffin stars as the young Sherlock, a brilliant but untested Oxford student who becomes the prime suspect when a fellow student is murdered. Clearing his name pulls him into a globe-spanning conspiracy involving stolen artifacts and a deadly weapon plot. Donal Finn appears as a young James Moriarty, with Joseph Fiennes as Sherlock's father and Colin Firth in a supporting role.

Debuting in March 2026 with all eight episodes, Young Sherlock earned generally favorable reviews, an 84% score on Rotten Tomatoes, for its energetic take on the character, and its trailer set a Prime Video record with 223 million views in a week; a second season is already in production. It is streaming on Prime Video.
