Mason Thames has been quietly building a résumé for years, but this fall the 18-year-old actor is getting the kind of moment most young performers wait a decade for.
He leads the live-action "How to Train Your Dragon" as Hiccup, a role that puts him at the center of one of Universal's biggest bets of the year.
For anyone who only knows him as the kid from "The Black Phone," this is the leap that changes the category.
The Dragon casting didn't come out of nowhere.
Thames had already proven he could carry a film's emotional weight in Scott Derrickson's 2021 horror hit, holding his own opposite Ethan Hawke with a performance that was more vulnerable than scary.
That mix of likability and quiet intensity is exactly what a studio wants when it's handing over a beloved animated franchise to a flesh-and-blood teenager.
What makes the timing interesting is how the internet has responded.
Clips of Thames in the Dragon trailer racked up millions of views within days, and the comment sections filled up with a familiar refrain: people saying they didn't expect to get emotional over a boy and a dragon again.
Nostalgia is a powerful engine, and Thames is riding it while still looking like a normal high schooler who wandered onto a soundstage.
He's also got range that the Dragon role alone doesn't reveal.
Thames came up through smaller parts in "For All Mankind" and "Walker," learning on sets where the stakes were lower and the notes were plenty.
Directors who've worked with him tend to mention the same thing: he listens, he adjusts, and he doesn't need to be told twice.
In an industry full of young stars who arrive fully packaged, he still reads as a working actor.
Some fans are calling him the next big leading man of his generation, which is the kind of praise that can curdle fast if a movie underperforms.
But Thames has something working in his favor that hype can't manufacture: he seems genuinely uninterested in being famous for its own sake.
His interviews are low-key, slightly awkward, and refreshingly free of the polished soundbites that make young actors sound like press releases.
That authenticity matters to the streaming-era audience that decides what trends.
Viewers who grew up on the original "How to Train Your Dragon" are now old enough to buy tickets and post reactions, and they're emotionally invested in whether the remake respects their childhood.
If he lands it, the conversation shifts from "who is this kid" to "what's he doing next." There's also a quieter story here about how Hollywood builds stars now.
Thames didn't come from a Disney Channel pipeline or a pop career.
He came from auditions, small roles, and one breakout horror film that made casting directors pay attention.
In a moment when studios are desperate for fresh faces with actual acting chops, that path looks less like luck and more like a blueprint.
If the Dragon remake connects, Thames becomes a name that gets attached to every YA adaptation and coming-of-age drama in development.
If it doesn't, he's still young enough to pivot, and his horror pedigree gives him a fallback that most teen leads don't have.
Our take: Thames is the rare young actor who benefits from being slightly under-famous right now.
Final Thoughts
The less the internet knows about him, the more room he has to actually become a movie star instead of just playing one online.
