Production

Development of a television series adaptation of the Young Sherlock Holmes books written by Andy Lane was first reported in April 2024 with Hero Fiennes Tiffin starring as a young Sherlock Holmes and Guy Ritchie attached to the project as well.[3] Amazon Prime Video ordered eight-episodes of the series in May 2024 to be executive produced by Inspirational Entertainment and Motive Pictures. The series was written by showrunner Matthew Parkhill, who also executive produces. Ritchie directs and executive produces alongside Lane, Simon Kelton, Ivan Atkinson, Simon Maxwell, Harriet Creelman, Dhana Gilbert, Colin Wilson and Marc Resteghini.[4] Ritchie previously helmed two unrelated cinematic Holmes adaptations: Sherlock Holmes (2009) and Sherlock Holmes: A Game of Shadows (2011). The role of the nineteen year old Holmes is played by Hero Fiennes Tiffin, who had previously worked with Ritchie on The Ministry of Ungentlemanly Warfare.[5]

In June, Fiennes Tiffin's uncle Joseph Fiennes was cast as Sherlock's father, alongside Natascha McElhone as his mother.[6] In July, Zine Tseng, Colin Firth and Dónal Finn joined the cast.[7][8][9] Max Irons was seen filming scenes in late August, and he was revealed to be playing Mycroft Holmes shortly afterwards.[10]

Filming of the series began in the United Kingdom in July 2024.[11] Scenes were filmed in Bristol.[12] In 2024, filming took place in Spain (specifically Jerez, Cádiz and Seville),[13][14][15] and Cardiff, Wales.[16][17] Filming on the series wrapped in late February 2025.[citation needed]
