How Old Was Finn Wolfhard In It Chapter 2

So, you’re rewatching It Chapter Two and suddenly wonder: how old was Finn Wolfhard when he played the young Richie Tozier? It’s one of those fun little trivia questions that pops up when you’re deep into a movie marathon. You’re not alone—plenty of fans get curious about the cast’s real ages compared to their characters.

Finn Wolfhard was sixteen years old during the filming of It Chapter Two in 2018. That might surprise you, because in the movie’s flashback scenes, the Losers’ Club is supposed to be around twelve or thirteen. But here’s the cool part: Finn was already a seasoned actor by then, thanks to Stranger Things and the first It film.

Why does his age matter so much?

Honestly, it’s impressive that a sixteen-year-old could still convincingly play a twelve-year-old. Think about it: most teens are towering over their parents by that age, but Finn’s youthful face and energetic vibe made him a perfect fit. Plus, he had to match the same energy from Chapter One, which he filmed when he was just fourteen.

It’s a bit like watching a time-lapse of a kid growing up on screen. In Chapter One (2017), Finn was fourteen and looked every bit the awkward, loud-mouthed Richie. By Chapter Two, he was sixteen and had to act younger than he actually was—which is a hilarious twist for an actor.

A quick age timeline for the curious

Let’s break it down simply: Finn was born on December 23, 2002. Filming for It Chapter Two started in June 2018, so he was fifteen turning sixteen during production. That means he was technically a year older than his character in the movie’s timeline, but still way younger than the adult actors (like James McAvoy, who was almost forty!).

Here’s what’s wild: the gap between his age in the first film and the second is only two years. But in the story, the Losers’ Club jumps ahead twenty-seven years. So Finn’s real-life aging is a tiny blip compared to the movie’s massive time skip. It’s like he hit pause on growing up for us.

Why is this cool for fans?

Because it makes you appreciate how believable the younger cast was. You don’t watch It Chapter Two and think, “Hey, that kid looks too old.” Instead, you’re completely sucked into the terror and nostalgia. Finn and the other young actors—like Sophia Lillis and Jack Dylan Grazer—had that magical ability to look both childish and wise at the same time.

Also, Finn Wolfhard has a face that just works for period horror. Whether he’s cracking a joke or staring down a cosmic clown, his age made the character feel authentic. Imagine if they’d cast a twenty-year-old to play a middle-schooler—you’d be yanked out of the story immediately.

So, does his age change how you see the movie?

Maybe a little. Next time you watch Chapter Two, pay attention to the scenes with young Richie. Notice how he still has that playful, adolescent energy that makes you believe he’s just a scared kid. For a sixteen-year-old to pull that off? That’s talent, plain and simple.

And here’s a fun comparison: Finn was almost the same age in the second film as Joseph Gordon-Levitt was in Third Rock from the Sun—both teens playing younger characters. It’s a weird little Hollywood hat trick. So the next time someone asks, “How old was Finn Wolfhard in It Chapter Two?” you can casually say, “Sixteen, but he looked twelve. And that’s why the movie works.”
