Mason Thames is an American actor born on July 10, 2007, making him 18 years old as of late 2025. A native of Dallas, Texas, Thames grew up in McKinney and attended school in Prosper, Texas. He was raised in an artistic family – his father, Byron Thames, is also an actor – and his older sister Brooke-Madison Thames is a trained ballet dancer. In fact, Mason followed Brooke into ballet training for four years, a discipline that later helped him develop an athletic, lean build on screen. Thanks to this dance background, he gained remarkable poise and even a keen sense of core strength (some fans note his toned abs), which benefits his action-oriented roles.
Beyond the studio lights, Thames keeps his private life mostly out of the spotlight. He has not publicly announced any girlfriend as of 2025, and while tabloids speculate about romances (often linking him with co-star McKenna Grace), there are no confirmed relationships. Instead, Mason remains focused on his craft. He celebrated his 18th birthday on July 10, 2025, marking another year of a career that started when he was just a child.
Breakthrough in Horror – The Black Phone and Beyond
Mason Thames’s film career took off with a chilling lead role. He made his feature-film debut as Finney Blake in the Blumhouse horror hit The Black Phone (2021). Acting opposite Ethan Hawke as a kidnapper known as “The Grabber,” Mason delivered a powerful performance that critics praised. In fact, director Scott Derrickson later said Thames has “a gift that very few actors…have” for conveying raw emotion onscreen. The movie earned generally positive reviews, and Thames’s role earned him widespread acclaim.

He reprised that character in The Black Phone 2, which was released on October 31, 2025. The sequel builds on the success of the first film, giving Mason a darker, more emotionally intense storyline. His return as Finney has been noted as one of the film’s strongest elements, with many viewers praising how he’s grown in the role while still keeping the heart of the character intact.
Shooting the sequel right after his dragon movie created a funny crossover moment – Thames told PEOPLE he sometimes found himself “sounding like Hiccup” while filming Black Phone 2, still coming down from his role as the Viking hero. Director Scott Derrickson would even quip on set, “I hear Hiccup,” when Thames slipped into the character’s voice.
In addition to The Black Phone, Mason has built a diverse résumé. He appeared on television in 2019 as Danny Stevens on Apple TV+’s sci-fi series For All Mankind, and later in three episodes as young Cordell Walker on The CW’s Walker reboot. On the big screen, he expanded beyond horror: Thames starred in the high-school comedy Incoming (2024) and the indie thriller Monster Summer (2024). Each role showcased his range and kept him on the radar for Hollywood producers.

Dream Role – How to Train Your Dragon Live-Action
One of the most buzzed-about moments of Mason Thames’s career is his casting as Hiccup Horrendous Haddock III in DreamWorks’ live-action remake of How to Train Your Dragon (2025). For Mason, it was a childhood dream come true – he grew up watching the original animated films and even dressed as Hiccup for Halloween as a kid. In interviews he’s been open about how he idolized the character. As Thames told PEOPLE, “Hiccup… was my hero growing up. There’s so much about him that I could relate to.”.
He also drew parallels between Hiccup’s story and his own: just as the young Viking had to prove himself, Mason found that “my journey becoming an actor reminded me a lot of Hiccup”. Landing the role was a landmark moment – Thames admits he literally “started freaking out” and “jumped out of [his] chair” when director Dean DeBlois offered him Hiccup’s part. It was, by Mason’s account, “one of the best moments” of his life.

As the reluctant hero Hiccup, Mason Thames brings a mix of youthful charm and sincerity to the live-action adaptation. The film also features Nico Parker as Astrid and veteran talent like Gerard Butler returning as Stoick the Vast. Fans have praised Mason’s dedication to the role — he trained with animal-handling consultants and even worked with a full-size Toothless puppet to capture Hiccup’s movements and bond with the dragon authentically. Both critics and audiences have been curious to see how he steps into a character originally voiced by Jay Baruchel, and many agree he makes the role his own.
Since the film’s release, Thames has stayed active in promoting it across events and interviews. With DreamWorks already confirming a sequel for 2027, Mason Thames looks set to continue leading the franchise, taking Hiccup’s story into its next chapter.
On-Screen Chemistry: Regretting You and the McKenna Grace Buzz
In another high-profile project for 2025, Mason Thames stars opposite McKenna Grace in Regretting You, a film adaptation of Colleen Hoover’s best-selling novel. The story centers on teenage romance and family drama – fitting, since Mason plays a character named Miller, the romantic lead opposite Grace’s character. This pairing immediately got fans talking: as Elle magazine noted, “Regretting You’s Mckenna Grace and Mason Thames are playing love interests”*, and their friendship off-screen has had people wondering if there’s more to the story. A TikTok video of Mason and McKenna playfully sharing a staged kiss in April 2025 went viral, fueling the rumor mill. They’ve also been seen together at events (including the film’s premiere) looking very comfortable with each other.
Despite the fan buzz, neither Thames nor Grace has confirmed any real-life romance. As one report put it, “neither actor has explicitly confirmed they’re romantically involved”. Mason himself has downplayed it, describing the viral kissing TikTok as a bit of on-set fun and saying he was “hilarious” at the reaction. In media interviews, he’s been complimentary about Grace, praising her work ethic, but he insists they’re just good friends and colleagues.
