In late July 2026, Prime Video announced that production on the second season of its teen‑detective series *Young Sherlock* had begun, with filming starting in late May in Palermo, Italy. Director and executive‑producer Guy Ritchie will return to direct the opening episode.

The season will add four new regulars—Olivia Williams, Indira Varma, Sophie Skelton and Aidan Gillen—joining lead Hero Fiennes Tiffin and returning cast members Dónal Finn, Natascha McElhone, Max Irons and Holly Cattle. Several Season 1 performers will not return, including Joseph Fiennes, Zine Tseng, Numan Acar and Colin Firth. The August 1 announcement reiterated the cast lineup and Ritchie’s continued creative role.

The first season attracted 45 million viewers in its first 28 days, reaching number 1 in over 95 countries and generating 63 % of its audience from international markets, establishing the series as one of Prime Video’s top‑performing originals.
