“Astounding. You should be a detective.” Ha ha. Prime Video has unveiled the first teaser trailer for a new Young Sherlock series streaming next March, another new Sherlock Holmes series coming up. This one is actually a spin-off from the Guy Ritchie movies (Sherlock Holmes in 2009, A Game of Shadows in 2011), described as an “explosive re-imagining of the iconic character’s early days.” From Guy Ritchie, witness the legendary beginning of Sherlock Holmes life in solving crimes in this “irreverent, action-laden mystery that follows the detective’s early adventures.” 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, culminating in an explosive showdown 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. Featuring Hero Fiennes Tiffin as Sherlock, with Dónal Finn as James Moriarty, Zine Tseng, Joseph Fiennes, Natascha McElhone, Max Irons, and Colin Firth as Bucephalus Hodge. Not sure why Holmes needs an origin story like this, hope it’s good.
