[INTERIOR. DAYTIME] HARRISON OSTERFIELD APPEARS ON SCREEN, SANS GEORGE CLOONEY WHO DIRECTED HIM IN THE “CATCH-22” MINI-SERIES, OR THE PRINCELY ATTIRE HE’S DONNED FOR “THE IRREGULARS,” HIS NEXT PROJECT SET IN THE SHERLOCK HOLMES UNIVERSE, WHICH WILL DROP ON NETFLIX THIS WEEKEND. AND SUDDENLY, A LOUD MEOWL IS HEARD.

The cat is ready to interview you now, Mr. Osterfield.
Love that. Those are the best Zoom meetings, when you’ve got a dog or a cat in the background. I will warn you, that’s where all my attention will go.

We’re about to be locked down again in Paris. How’re things for you in London?
I’m in my flat in South London, and I feel like I’ve gone through every lockdown activity there is to do. Baking classes, yoga classes, zoom cocktail classes – I feel like I’ve done it all. I’m lucky that I have a bit of space so I can exercise outside a bit.

What’s your forte then?
Definitely not the baking. I’ve tried that a couple of times and it hasn’t turned out too well. So I’d say the cocktail making, but I can’t really remember them.

They must have been good then. Maybe ask Sherlock Holmes to give you a hand at sleuthing what they were?
A key part of investigation is remembering things, yeah. And I struggle at that. (Laughs.) So I’m glad I’m play acting it and not having to do it in real life.

So why become one of the Irregulars?
Sherlock is really at the lowest of the low, and he’s a shell of the man he once was. He can’t solve these crimes that he once could. So out of necessity, Dr. Watson really turned to these five kids who get thrust into a series of investigations. They, or rather we, start taking on these sort of investigations and crimes, and start to realize that something much more sinister and possibly darker is going on. It’s a very different Sherlock to the one that we’ve seen before. Our showrunner, Tom Bidwell, has done an amazing job of taking the may four or five lines out of Arthur Conan Doyle’s work that mention the Baker Street Irregulars and create this eight-hour episodic extravaganza.

And if that wasn’t an excellent lockdown activity on his part, I don’t know what is.
Yeah, exactly. I wish I could do that. I’ve just been messing up baking every day.

At least you went from baking to Baker Street.
I will say that. That is a very good connection. I should have run with that.

You mentioned you’d be the posh kid of the Irregulars. How posh are we talking?
Not just posh. He’s actually a prince of England, Queen Victoria’s youngest son. And in the first episode, he decides not to tell the other regulars that he is a prince. And I think that’s because he wants to sort of be accepted as a normal teenager and not have these things that have been held holding him back his whole life.

And let me guess: he has a gorgeous American actress wife in his future.
(Laughs.) Yeah, probably. Leo’s been kept in his room at Buckingham Palace for 17 years of his life, so he doesn’t really have any friends his own age. So that’s why he wants to experience London and on his very first outing, he encounters the other Irregulars.

What about you? How posh are you in real life? Do you know your fish knife from your butter knife?
I definitely fell into that sort of princely thing quite quickly. My first day on set, I put on this incredible princely royal attire and just went “yeah, this is for me.” (Laughs.) In real life, I’m pretty posh but when I read the script and saw how well-mannered and well-spoken he was, I started taking notes whenever I spent time with my granddad, who is just the most perfect man in terms of being well-spoken and perfectly mannered. I can’t wait for lockdown to end, so I can take up the curry night tradition I have with him and one of my cousins.

So how’re you occupying your time until curry’s on the menu again?
At the moment, I’m gearing up for the release of the Irregulars. It’s been a very big part of my life for the last two years. But as an actor, you have long stretches of time where you’re between roles, so I’ve set up a sustainable marketing company with some of my school friends.

It’s called Addvert, with the double D. You see the #ad hashtag on social media? Well, this is about going the extra mile to ensure the profits are going to charity or that the product we are supporting is a genuinely sustainable one, not just something that’s been greenwashed. We work on fundraisers for charities that we support or doing campaigns for sustainable products online or projects promoting mental health. It’s been really rewarding and fun.

What’s the product that we should all be paying attention to, then?
An amazing search engine called Ecosia. It’s very similar to Google, except that each search contributes to getting trees planted in Madagascar and South America. It’s quite an easy thing to put into your life and the benefits are there. So we’ve got quite a few projects like these coming up. They’re all under wraps at the moment, but I’m excited for the future.
