With all the wit and charm of Guy Ritchie’s Sherlock Holmes feature films, Young Sherlock follows the origin story of Sir Arthur Conan Doyle’s beloved detective in an explosive re-imagining of this character’s early days. Sherlock Holmes is a disgraced young man – raw and unfiltered – when he finds himself wrapped up in a murder case that threatens his liberty.

His first ever case unravels a globe-trotting conspiracy that changes his life forever. Unfolding in 1870s Oxford and adventuring abroad, the series will expose the early antics of the anarchic adolescent who is yet to evolve into Baker Street’s most renowned resident.

Previously announced cast members of Young Sherlock include 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). Guy Ritchie directs the first two episodes and executive produces.

The series is created for television and executive produced by showrunner Matthew Parkhill with executive producers Dhana Rivera Gilbert, Marc Resteghini, Simon Maxwell, Ivan Atkinson, Simon Kelton, Colin Wilson, and co-executive producers Harriet Creelman and Steve Thompson. Motive Pictures led physical production for Young Sherlock.
