Before he became Baker Street's most renowned resident, Sherlock Holmes was a disgraced young man wrapped up in a murder case that threatened his liberty.
Young Sherlock, premiering on Prime Video in 2026, will explore the iconic detective's early adventures in an irreverent, action-laden mystery series.
Guy Ritchie, who previously directed the Sherlock Holmes feature films starring Robert Downey Jr., serves as the director of the first two episodes and executive producer for Young Sherlock.
The series follows the origin story of Sir Arthur Conan Doyle's beloved detective in an explosive re-imagining of Sherlock's early days. Unfolding in 1870s Oxford and adventuring abroad, Young Sherlock exposes the early antics of the anarchic adolescent before he evolved into the master detective fans know today. His first ever case unravels a globe-trotting conspiracy, culminating in an explosive showdown that changes his life forever.
