‘Young Sherlock’ creator Matthew Parkhill says Hero Fiennes Tiffin stood out from the very first audition, and that early moment helped shape the Prime Video series. Parkhill also opened up about the pressure of handling one of fiction’s most famous characters and explained how the show sets itself apart from earlier versions of Sherlock Holmes. Along the way, he shared a surprising link to Indian cinema, revealing that one actor in the series also appeared in the Bollywood film ‘Lagaan.’ His comments offer a closer look at how the new series took form.
‘Young Sherlock’ Hero Fiennes Tiffin casting details
Speaking to Hindustan Times about the casting process, Parkhill said Hero Fiennes Tiffin was the first actor to audition for the role of Sherlock. He said co-creator Guy Ritchie already knew the actor from ‘The Ministry of Ungentlemanly Warfare,’ but the audition still made a strong impression. “Guy Ritchie (co-creator) had worked with Hero on a movie called ‘The Ministry of Ungentlemanly Warfare.’ So he knew him already but Hero was the first person to audition for the role,” Parkhill said.Parkhill added, “I remember, when we did his audition, he was on holiday in Thailand and he did a Zoom call from his hotel room. In the show, Sherlock has a sense of wonder and innocence in the way he looks at the world. Hero did that on that first read and then all the other Sherlocks I met after that, I kept coming back to Hero. That’s usually a sign that he’s your man for the role.”
‘Young Sherlock’ and ‘Lagaan’ connection explained
Parkhill also said he worked hard to make ‘Young Sherlock’ feel fresh instead of repeating what audiences had already seen. He admitted he felt nervous because so many “brilliant writers and actors” had already worked on Sherlock Holmes stories. To find his own way in, he returned to the books. “I thought I will not touch anything after the first book, ‘Studying in Scarlet,’ and before that is my playground,” he said, explaining that this gave him “creative permission to play.”That approach also shaped how he viewed Sherlock in the series. Parkhill said this version begins as a young man, not yet the detective the world already knows. “In every Sherlock adaptation before, he’s already a detective. But here, if he’s not a detective, he’s not just going to take a case,” he said. “In this show, it is more like he is pulled into the case.”He also wanted to explore how Sherlock became the eccentric figure readers know from Arthur Conan Doyle’s work. Parkhill called him “a very strange character,” “very eccentric,” and “an oddball,” then said he became interested in asking, “how does he become that person?”For Indian audiences, Parkhill also revealed an unexpected link to ‘Lagaan.’ He said, “There’s a character Mrs. Tilcott in the later episodes, who adopts or looks after a major character in the show. She played Elizabeth in ‘Lagaan.’” Looking ahead, Parkhill said he already sees “multi-seasons” for the series and hopes to continue if viewers embrace it.‘Young Sherlock’ is a 2026 eight-episode series directed by Guy Ritchie and led by Hero Fiennes Tiffin. It premiered on Amazon Prime Video on March 4, 2026. The story follows a 19-year-old Sherlock Holmes at Oxford University as he takes on his first major murder case. Impulsive and sharp, this young version of Sherlock is still finding his footing while stepping into a dangerous mystery.
