Young Sherlock is shaping up to be one of the most fun shows on streaming this month. With legendary director Guy Ritchie at the helm it's a fast-paced, swaggering, hugely entertaining gem of a show that's already attracting rave reviews. Young Sherlock is streaming on Prime Video worldwide from this week, 4 March, and all eight episodes are dropping at once.

Young Sherlock features Hero Fiennes Tiffin as the legendary detective, but in this show that fame is far in the future. Here he's an anarchic adolescent in what Prime Video says is "an irreverent, action-laden mystery that follows the iconic detective’s early adventures."
In addition to Tiffin in the title role, who you may recognise from the After series of movies and Harlan Coben's Safe, Young Sherlock is packed with familiar faces including Dónal Finn (The Wheel of Time), Zine Tseng (3 Body Problem), Joseph Fiennes (The Handmaid’s Tale), Natascha McElhone (Halo), Max Irons (Condor) and Colin Firth (The King’s Speech). And of course director and executive producer Guy Ritchie has a long association with Sherlock Holmes: he directed the Sherlock Holmes movie and its sequel, Sherlock Holmes: A Game of Shadows.
