With Guy Ritchie leading the troops, “Young Sherlock” promises to be a propulsive19th century rendering of Sir Arthur Conan Doyle’s iconic detective, seen for the first time as an “anarchic adolescent” teenager in Prime Video’s 8-episode adventure series.

This Holmes is embodied by Hero Fiennes Tiffin, 28, who, yes, is indeed a member of the storied thespian family that includes his uncles Joseph Fiennes (“Shakespeare in Love”) and Ralph Fiennes.

He certainly stands out being named Hero.

“It’s a lot to live up to,” Tiffin conceded in a Zoom interview from London. “I feel like my parents took it upon themselves to use naming their kids as a chance to demonstrate their creativity which I’m now really grateful for. It’s a great icebreaker.”

Growing up in this family, was there ever a doubt about acting?

“My parents are both in the industry as well” — Martha Fiennes directs, George Tiffin is a cinematographer – “and growing up I felt like what your parents do isn’t very cool.

“So like almost every other kid in South London, I grew up wanting to be a footballer. That’s a very, very difficult thing to do. So, later I was very lucky to have acting opportunities through my family at a young age. By the time I got to 17, I started to take it a bit more seriously.”

That just happens to be when we meet Sherlock. How different is he from old Sherlock?

“A very good question,” Tiffin allowed. “Hopefully, different enough to warrant telling an origin story. But similar enough for people to believe that he would eventually become the character that Conan Doyle created that we all know and love.

“That was a challenge I was aware of when developing the character. What was important was placing him somewhere where audiences recognize the similarities, the natural curiosity and brilliant mind Sherlock has, but also placing him further enough away.

“We aren’t telling how he became this enigma, this incredible detective that we all know and love. But where to put him on the scale was something we were really conscious of.

“In a lot of Conan Doyle’s works the portrayals we see of his later life, he is emotionally shut off. Cold and distant from the world.

“I always love how when he’s solving crimes, where other people are very emotionally affected, like the crime victims, he’s completely, emotionally detached.

“I find that quite funny to watch, onscreen anyway. So I’ve enjoyed exploring the mysteries that are closer to home and affect him more emotionally.

“We’re trying to give him a youthful positivity. If we’re lucky enough to have more seasons and continue to document his journey, sadly, we’re going to see those traits slowly wear off.”

Prime streams all 8 episodes of “Young Sherlock” on March 4.
