Mason Thames
Mason Thames has a way of stopping viewers from scrolling.
Maybe it’s the way he carries an entire horror film on his teenage shoulders. Maybe it’s the fact that he played opposite Ethan Hawke and never once looked like the junior actor in the room. Whatever the reason, people want to know more — his age, his height, what he’s working on next, and whether the McKenna Grace dating rumors hold any truth.
Here’s everything confirmed, verified, and worth your time.
How Old Is Mason Thames?
Mason Thames was born on July 25, 2007, in Phoenix, Arizona. As of mid-2026, he is 18 years old and will turn 19 this coming July.
That number surprises people every time. He was 14 when he filmed The Black Phone and just 17 when How to Train Your Dragon wrapped. For someone with his level of screen presence, 18 feels almost impossible — yet the birth records don’t lie.
How Tall Is Mason Thames?
Based on consistent reports from public appearances and on-set sources, Mason Thames stands at roughly 5 feet 7 inches (approximately 1.70 meters).
He’s still in his late teens, so a modest growth spurt remains possible. For now, his lean build suits him well in physically active roles, giving directors a leading man who can sprint through a basement scene without it looking staged.
Mason Thames Movies: Every Role, Listed
His resume moves fast for someone his age. Here’s a clean look at every confirmed screen credit through mid-2026:
| Year | Title | Role | Notes |
|---|---|---|---|
| 2019 | For All Mankind (TV) | Young Danny Stevens | Guest appearance |
| 2022 | The Black Phone | Finney Shaw | Lead role, breakout performance |
| 2022 | The Gray Man | Young Six | Flashback sequence |
| 2025 | How to Train Your Dragon | Hiccup Horrendous Haddock III | Live-action lead |
| 2026 | The Black Phone 2 | Finney Shaw | In active development |
He went from a single-episode guest spot to leading a $161 million horror hit in three years. That kind of trajectory is rare in Hollywood at any age.
The Black Phone: Why This Role Changed Everything
If you want to understand Mason Thames’s career, start here.
Scott Derrickson’s The Black Phone (2022) put him opposite Ethan Hawke in a story about a kidnapped boy who communicates with previous victims through a disconnected rotary phone. The premise sounds wild. The execution was devastating.
Thames played Finney Shaw with a quiet, controlled terror that never tipped into melodrama. Critics singled him out specifically — not as “impressive for his age” but as genuinely effective full stop. The film grossed over $161 million worldwide, and his performance was the emotional engine behind every dollar of that run.
The sequel is now in development with Thames expected to return as Finney. That alone tells you how the industry feels about what he delivered the first time.
How to Train Your Dragon (2025): The Next Big Swing
Landing the role of Hiccup in the live-action How to Train Your Dragon adaptation was a significant shift — from indie horror to DreamWorks blockbuster territory. The casting was first reported by Deadline, and it confirmed what many in the industry had already started saying quietly: Mason Thames is the kind of young actor studios build franchises around.
Mason Thames Girlfriend: What’s Actually Known
Search traffic around “Mason Thames girlfriend” spikes after every interview or red-carpet appearance. The honest answer in 2026 is simple: he has not publicly confirmed a romantic relationship with anyone.
He keeps his personal life deliberately private. There are photos with friends and co-stars at events, but nothing that constitutes evidence of a relationship. His approach to fame has been consistent since day one — share the work, protect everything else.
Are Mason Thames and McKenna Grace Dating?
This rumor picked up speed after the two appeared at industry events and exchanged friendly posts on social media. McKenna Grace, known for Ghostbusters: Afterlife and The Handmaid’s Tale, and Thames have an obvious on-screen-peer chemistry that reads as warm and genuine.
But neither has ever confirmed a romance. Interviews from both actors describe their relationship in professional, collegial terms. No verified outlet has reported otherwise. The dating narrative appears to be exactly what fan communities sometimes create from two people simply being friendly and talented at the same time.
Early Life: How He Got Here
Thames grew up in Southern California after being born in Phoenix. He came to acting through local theater and short films — not through a viral video or industry connection. His parents recognized an early drive and supported him through small auditions before the For All Mankind opportunity arrived.
What followed wasn’t an accident. He worked with acting coaches, studied classic films, and spent serious time on craft before walking onto the set of The Black Phone. That preparation is audible in every quiet moment of the performance.
He’s cited Ethan Hawke and Joaquin Phoenix as actors he studied closely — both known for disappearing into difficult characters rather than decorating them. That influence shows.
Mason Thames’s Upcoming Projects
Two threads to follow right now:
The Black Phone 2 — Officially in development, with Thames expected to reprise Finney Shaw. Tone and plot details remain closely guarded, but the studio has confirmed the sequel is moving forward.
A psychological thriller — Industry sources have hinted at a new project pairing him with another well-regarded director. Nothing confirmed publicly as of this writing.
Given his track record of choosing roles that demand emotional weight rather than spectacle, expect his next announcement to be interesting.
