Colin Firth has boarded Young Sherlock, Prime Video’s new series from Guy Ritchie, which tells the origin story of Sir Arthur Conan Doyle’s beloved detective. He joins previously cast Hero Fiennes, Zine Tseng, Joseph Fiennes and Natascha McElhone.

Written by Matthew Parkhill inspired by Andy Lane’s Young Sherlock Holmes book series, the show re-imagines Sherlock Holmes at age 19. Disgraced, raw, unfiltered, and unformed, he finds himself caught up in a murder mystery at Oxford University which threatens his freedom. Diving into his first-ever case with a wild lack of discipline, Sherlock (Fiennes Tiffin) manages to unravel a globe-trotting conspiracy that will change his life forever.

Firth will play Sir Bucephalus Hodge. Fiennes and McElhone play Sherlock’s parents; Tseng plays Princess Gulun Shou’an.

Ritchie will be directing and executive producing. Parkhill will serve as executive producer and showrunner. Simon Kelton, Ivan Atkinson, Simon Maxwell, Dhana Gilbert, Colin Wilson, Marc Resteghini also executive produce. Harriet Creelman co-executive produces. Physical production is running through Motive Pictures.

Oscar winner Colin Firth was recently seen as Michael Peterson in the 2022 Max limited series The Staircase, which warned him his second Emmy nomination. (His first one was for the 2001 HBO film Conspiracy.) He is repped CAA and Independent Talent.
