Mason Thames is an American actor who has quickly become one of the recognizable young faces in Hollywood. Born on July 10, 2007, he began performing at a young age and developed his skills through ballet before moving into acting. His early experience as a dancer helped him build confidence, discipline, physical awareness, and an understanding of performance that later became useful on film and television sets.
Thames first attracted wider attention through his role as Finney Blake in the supernatural horror film The Black Phone. The performance placed him opposite Ethan Hawke and gave him a demanding lead role at a very young age. He later returned as Finney in Black Phone 2, expanding on one of the performances that originally introduced him to a much larger audience.
His career then moved into different genres. He appeared in projects such as Incoming and Monster Summer before taking on one of his most recognizable roles, Hiccup Horrendous Haddock III, in the 2025 live-action adaptation of How to Train Your Dragon. The role was particularly meaningful because Thames had been a fan of the animated franchise before eventually being cast as its central character.
With appearances in horror, comedy, adventure, fantasy, and romantic drama, Mason Thames has continued expanding his acting range. His recent credits include Regretting You, Black Phone 2, How to Train Your Dragon, and other film projects, while his career continues to develop.

Who Is Mason Thames?
Mason Thames is an American actor who began working professionally while still young. Although many audiences discovered him through The Black Phone, his entertainment journey started before that film. His early years included ballet training and performance experience, giving him a foundation in movement and stage discipline.
His screen career includes both television and feature films. One of his early notable television appearances came in Apple TV+’s For All Mankind, where he appeared as Daniel Stevens in several episodes. He also played a younger version of Cordell Walker in Walker.
The major turning point arrived with The Black Phone. Playing Finney Blake required Thames to carry many emotionally intense scenes, and the film gave him an opportunity to demonstrate that he could lead a feature rather than simply appear as a young supporting performer.
After that breakthrough, Thames continued accepting projects from different genres. His later work includes teenage comedy, family adventure, horror, fantasy, and romance. This variety has become an important part of his developing filmography.
Mason Thames Age and Birthday
Mason Thames was born on July 10, 2007. As of September 2026, he is 19 years old. His birthday places him under the Cancer zodiac sign.
His age is an important part of his career story because he entered professional entertainment while he was still a child and reached major film roles during his teenage years. Instead of waiting until adulthood to begin building a filmography, Thames accumulated television, short-film, dance, and feature-film experience from an early stage.
Because many of his most recognizable roles were played when he was a teenager, older articles can contain outdated information about his age. Articles describing him as 16, 17, or 18 should be understood according to their publication date rather than treated as his current age.
Mason Thames Early Life
Mason Thames developed an interest in performance before becoming widely known as an actor. According to biographical interviews and profiles, he grew up in Texas and was exposed to movies and performance from an early age.
His early interests were not limited to acting. Ballet became a major part of his childhood. Thames trained in ballet alongside his sister Brooke-Madison Thames and eventually performed with a professional ballet company. He toured from 2013 through 2016 and performed in The Nutcracker.
That background is significant because dance can teach performers skills that transfer directly to acting. Ballet requires coordination, repetition, body awareness, timing, concentration, and the ability to communicate emotion through movement. Those qualities can be useful when working in front of a camera, especially during physically demanding scenes.
Thames later shifted his attention toward acting. His transition did not erase his dance background. Instead, it became another part of his overall performance training.
Mason Thames and Ballet
Before audiences knew Mason Thames as Finney or Hiccup, he was already familiar with professional performance through ballet.
Thames trained in ballet for several years and toured with a professional company as a child. His sister Brooke-Madison Thames also developed a strong background in dance. This shared interest gave the siblings an early connection to the performing arts.
Ballet is also an interesting part of Thames’s career because his later acting roles have included physical and action-oriented work. Training in dance can help an actor understand posture, movement, rhythm, balance, and physical characterization.
His experience demonstrates that an actor’s preparation does not always begin with acting classes alone. For Thames, years of dance contributed to his development as a performer before his film career became his main focus.
Mason Thames Family and Sister
Mason Thames comes from a family that supported his involvement in the performing arts. His older sister is Brooke-Madison Thames, who also has a background in dance and ballet. Public profiles describe Brooke as a dancer and ballerina.
Thames has spoken about his family and his childhood experiences with performing. His father’s influence has also been mentioned in interviews, including stories about watching movies together and developing an early interest in cinema.
Some entertainment websites publish different names for Thames’s parents, while others provide incomplete family information. Because those details are not consistently documented across reliable public sources, it is better not to treat conflicting parental names or family claims as established facts.
What is clear is that family support played an important role during Thames’s childhood, particularly while he balanced school, dance, auditions, travel, and professional acting opportunities.
Mason Thames Education
Detailed information about Mason Thames’s education is relatively private. Public biographies indicate that he attended school while growing up in Texas, including time in the Prosper area, but a comprehensive record of his schooling has not been widely published.
This is understandable given that Thames entered professional entertainment at a young age. Child and teenage performers often have to balance traditional education with auditions, rehearsals, travel, filming schedules, and other professional commitments.
Rather than relying on unsupported claims about his private education, the better-documented part of his early development is his training and experience in performance.
Mason Thames Acting Career
Mason Thames began building his acting career before his major breakout. His early screen work included the short film After Omelas, followed by television appearances.
His television credits include For All Mankind, where he played Daniel Stevens, and Walker, where he portrayed a younger version of Cordell Walker. These roles gave him experience working within established television productions.
The move from television appearances to a major feature-film lead represented a significant step in his career. That opportunity came with The Black Phone.
Since then, Thames has continued moving between different types of productions instead of remaining associated with only one genre. His filmography includes horror, comedy, adventure, fantasy, and romance.
Mason Thames in The Black Phone
The Black Phone became the breakthrough project that introduced Mason Thames to a much larger audience.
In the film, Thames plays Finney Blake, a young boy who becomes trapped by a masked kidnapper portrayed by Ethan Hawke. The story places much of its emotional and dramatic weight on Finney, making Thames one of the central performers in the movie.
The role was particularly demanding because Finney’s experience involves fear, isolation, uncertainty, and attempts to survive an extremely dangerous situation. Thames had to communicate much of that experience through facial expressions, reactions, and dialogue while working within the tense atmosphere of a horror film.
The movie helped establish him as more than a child performer. It showed that he could handle a central dramatic role in a feature film.
Director Scott Derrickson selected Thames from a large group of applicants and publicly praised the young actor’s ability to process emotional moments naturally without excessive performance.
Mason Thames in Black Phone 2
Mason Thames returned as Finney in Black Phone 2, continuing the character’s story after the original film.
The sequel gave Thames an opportunity to revisit a character who had been closely associated with his early rise to prominence. Returning to an established role can present a different challenge from creating a new character because the actor has to preserve the character’s identity while also showing how that person has changed.
Black Phone 2 was among Thames’s major 2025 projects and helped keep the actor connected to the franchise that originally brought him widespread attention.
Mason Thames as Hiccup in How to Train Your Dragon
One of the biggest milestones in Mason Thames’s career came when he was cast as Hiccup Horrendous Haddock III in the 2025 live-action version of How to Train Your Dragon.
Hiccup is the central character of the story, a young Viking who does not fit the traditional image of a warrior. His relationship with Toothless, a Night Fury dragon, becomes the foundation of the story and challenges the long-standing conflict between Vikings and dragons.
Thames’s casting was especially notable because he had been a fan of the animated franchise since childhood. Profiles have reported that portraying Hiccup was a long-standing personal ambition, making the role more meaningful than a typical casting opportunity.
The live-action film was directed by Dean DeBlois, who was closely involved with the original animated trilogy. Thames appeared alongside Nico Parker as Astrid, Gerard Butler as Stoick, Nick Frost as Gobber, and other members of the ensemble cast.
The role required Thames to combine emotional acting with physical performance, fantasy adventure, and the distinctive mannerisms associated with Hiccup.
Why Hiccup Became an Important Role for Mason Thames
Hiccup represents a major change from Finney Blake.
Finney is a frightened teenager placed in a horror story, while Hiccup is an inventive Viking teenager whose curiosity leads him to challenge the beliefs of his community. The characters operate in completely different worlds and require different performance approaches.
For Thames, playing Hiccup demonstrated his ability to move from a dark horror franchise into a large-scale fantasy adventure. It also placed him at the center of a globally recognized story with an established fan base.
His previous experience with physical performance through ballet was another useful part of his preparation. Hiccup’s story involves movement, action, training, flying sequences, and interaction with a digital dragon character.
Mason Thames Movies

- The Black Phone as Finney Blake
- Incoming as Benj Nielsen

- How to Train Your Dragon as Hiccup
- Black Phone 2 as Finney
- Regretting You as Miller Adams
- Nimrods

His movie career is notable for its variety. Rather than repeating the same type of role, Thames has moved between horror, comedy, adventure, fantasy, and romantic drama.
Mason Thames TV Shows
Mason Thames also has television experience dating back to his early acting years.
His television credits include:
For All Mankind
Thames appeared in For All Mankind as Daniel Stevens. The series gave him an early opportunity to work in a major television production and become familiar with professional filmmaking.
Walker
He also appeared in Walker, playing a younger version of Cordell Walker. This role allowed him to work within a television franchise while portraying a character at a different age.
These early television roles were important stepping stones before his feature-film breakthrough.
Mason Thames in Incoming
In 2024, Thames appeared in Incoming, a coming-of-age comedy centered on high school students and their experiences at a major party.
He played Benj Nielsen in the film. The project was considerably lighter in tone than The Black Phone, giving audiences a different look at his range.
Moving into comedy was another useful development because comedic acting often depends on timing, reactions, chemistry with other performers, and an ability to create believable awkward or unexpected moments.
Mason Thames in Monster Summer
Thames also starred in Monster Summer, a coming-of-age adventure thriller directed by David Henrie.
He played Noah Reed in the film and appeared alongside Mel Gibson and other cast members. The project combined elements of childhood adventure, mystery, and supernatural storytelling.
The film further demonstrated Thames’s ability to work in stories that blend young characters with darker or more mysterious themes.
Mason Thames in Regretting You
Another significant project in his filmography is Regretting You, a romantic drama based on Colleen Hoover’s novel.
Thames plays Miller Adams in the film and appears alongside Mckenna Grace and other established performers. The project represents another shift in genre for Thames, moving away from horror and fantasy toward relationship-focused drama.
The variety of roles in his recent filmography shows how his career has been expanding beyond the role that first made him famous.
