Okay, let’s be real for a second. Have you ever found yourself deep in a House of the Dragon rabbit hole, watching Prince Jacaerys Velaryon fly through the clouds, and suddenly thought, “Wait… how old is that actor?” You aren't alone. It’s a totally normal curiosity, especially when the characters age so fast on screen.
So, let’s talk about Harry Collett. He’s the young British actor who brings Jace to life with such intensity and quiet dignity. By the time 2026 rolls around, how old will this rising star actually be?
Let’s do the simple math, shall we? Harry Collett was born on March 17, 2004. That makes him a spring baby, a Pisces to be exact. If we fast-forward to 2026, he’ll be turning 22 years old.

Think about that for a second. Twenty-two. That’s the age where you’re officially an adult, but still young enough to make questionable decisions about late-night snacks. It’s the sweet spot between college graduation and real responsibility.
What’s really cool is how his age aligns with his character’s timeline. In House of the Dragon, Jace starts as a shy kid and grows into a commander and heir by the end of Season 2. Harry was around 18 when he first played the role, which is a wild jump from playing a ten-year-old prince in flashbacks.
Why 22 feels like the perfect age for Harry
At 22, you’re still riding the wave of your early twenties. You’re not a teenager anymore, but you’re also not fully settled. It’s an exploratory age, full of energy and potential. That fits Harry’s career perfectly right now.

He’s already got an impressive resume for someone so young. Before dragons, he was in Dunkirk and the BBC’s Doctors. He even voiced a character in Thomas & Friends, which is the kind of childhood job that makes you smile.
By 2026, he’ll have more experience under his belt. He’ll likely be filming seasons 3 or even 4 of House of the Dragon. Can you imagine carrying a massive fantasy show on your shoulders at just 22? That’s a lot of pressure, but he handles it like a pro.
Fun comparisons to make you smile
Let’s put it in perspective. At 22, most of us are figuring out how to do laundry without shrinking our favorite sweater. Harry is out there memorizing High Valyrian lines while riding a CGI dragon named Vermax. Not the same thing, right?

Here’s another one: at 22, Tom Holland was swinging through Spider-Man: Far From Home. At 22, Zendaya was starring in Euphoria and Spider-Man. Harry’s walking a similar path—young, talented, and about to explode into global fame.
Even funnier? When he’s 22, he’ll still be younger than some of the characters he plays. Jace is supposed to be about 24 or 25 by the time the Dance of the Dragons really heats up. So Harry is actually playing older than he is, which is a classic actor trick.
What will Harry be doing at 22?
We can only guess, but the signs point upward. He’s already been nominated for awards, and his performance in Season 2 of House of the Dragon was praised for its emotional depth. By 2026, he might be leading his own spin-off or a huge movie.

One thing’s for sure: he won’t be stuck in a cubicle. He’s living the dream, and it’s only getting bigger. Every new season adds layers to his character, and at 22, he’ll have the maturity to handle even darker material.
It’s also interesting to think about his personal life. At 22, he’ll probably be more open about his hobbies, his favorite video games, or his go-to comfort food. We already know he loves Star Wars and sports, so maybe he’ll start a podcast or something.
The bottom line on Harry Collett’s age
So, to answer the burning question: Harry Collett will be 22 in 2026. That’s a prime age to be a leading man in a massive franchise. It’s also the age when you start realizing that your twenties go by fast, so you’d better enjoy the ride.
Harry Collett's profile: Age and all about the House of the Dragon star
Isn’t it funny how we get so invested in an actor’s age? It’s like we’re trying to figure out if they’re “old enough” to play a king or a warrior. But really, age is just a number—especially when you have dragon fire and a good script.
Next time you watch Jace argue with Rhaenyra or fly across the Stepstones, just remember: the guy playing him is probably still figuring out his own laundry situation. And that’s what makes him so relatable, even when he’s saving a kingdom.
Keep an eye on Harry Collett. 22 is just the beginning for this actor, and honestly, we can’t wait to see what he does next. For now, we’ll just enjoy the ride, one dragon flight at a time.
