Guy Ritchie’s Young Sherlock, with Hero Fiennes Tiffin as a nineteen-year-old Holmes at Oxford, had its world premiere at the Queen Elizabeth Hall.
Guy Ritchie’s Young Sherlock, a Prime Video series, had its world premiere at the Queen Elizabeth Hall on the South Bank on Tuesday 24 February 2026.
Ritchie was born in Hatfield, Hertfordshire, in 1968 and left school at fifteen. He directed commercials before Lock, Stock and Two Smoking Barrels in 1998 and Snatch in 2000 made his name. In 2009 and 2011 he directed Robert Downey Jr. in Sherlock Holmes and A Game of Shadows.
Created by Matthew Parkhill and developed with Ritchie, who directed two episodes, the series draws on Andrew Lane’s Young Sherlock Holmes books. Holmes is 19, at Oxford and not yet disciplined, when a murder makes him a suspect and brings him into the company of James Moriarty.
Hero Fiennes Tiffin, the young Tom Riddle of Harry Potter and the Half-Blood Prince, plays Holmes, and his uncle Joseph Fiennes plays his father, Silas. Zine Tseng plays a scholar posing as a princess of the Qing dynasty.
For the night the hall held a replica of the door of 221B Baker Street. Dónal Finn and Max Irons joined Ritchie, Tseng and both Fienneses on the carpet, eight days before Prime Video released all eight episodes.
