Ahead of its Prime Video premiere on March 4, Guy Ritchie's Young Sherlockhas presented us with another trailer showing off Hero Fiennes Tiffin as the rough-around-the-edges sleuth. Also starring the lead actor's real-life uncle Joseph Fiennes (as Silas Holmes), Natascha McElhone (Cordelia Holmes), Colin Firth (Sir Bucephalus Hodge), Max Irons (Mycroft Holmes), Zine Tseng (Princess Gulun Shou'an), and Dónal Finn (James Moriarty), this eight-episode series looks like everything you'd expect from a Ritchie joint.
