Mason Thames has quickly become one of the young actors to watch in Hollywood. Born on July 10, 2007, in Dallas, Texas, he first gained major attention as Finney Blake in The Black Phone. Since then, his career has expanded into comedy, fantasy, drama, and major studio productions, including How to Train Your Dragon and Regretting You.
As of 2026, Mason Thames is 19 years old. Fans often search for his age, birthday, height, Instagram account, and movie roles because they have watched him grow from a teenage horror star into a leading young actor. This guide covers those details while also looking at how old he was in some of his best-known movies.
Mason Thames Age – Rising Hollywood Star
Mason Thames was born on July 10, 2007, making him 19 years old in 2026. He was born in Dallas, Texas, and began building his acting career while still very young. IMDb lists his acting credits from productions including For All Mankind, The Black Phone, Incoming, Monster Summer, and several later feature films.
Before becoming widely known as an actor, Thames also trained in ballet. According to his IMDb biography, he toured with a professional international ballet company from 2013 to 2016 and was the youngest cast member. He later moved into acting, making his television debut in For All Mankind.
His breakthrough came with The Black Phone, where he played Finney Blake opposite Ethan Hawke. The role put him at the center of a major horror film while he was still a teenager.
His career then moved into bigger projects. In 2025, he played Hiccup in the live-action How to Train Your Dragon, reprised Finney in Black Phone 2, and appeared in Regretting You.
Mason Thames Images
Mason Thames images from red carpets, movie premieres, interviews, and film sets show how much his appearance has changed since his early acting roles. Because he started working professionally at a young age, fans have been able to follow his transition from a child actor to a young adult performer.
His most recognizable images come from The Black Phone, where he appeared as Finney Blake. Later promotional photography for How to Train Your Dragon presented a very different look, reflecting his role as Hiccup.
For readers looking for current photos, social media and official movie publicity channels are generally more useful than older celebrity biography pages. Images can also vary depending on the year, hairstyle, clothing, posture, and whether a photo was taken during filming or at a public event.
Mason Thames Instagram
Mason Thames is active on Instagram under the handle @masonthames. A current Instagram analytics listing identifies the account by that username, while a production-related source for Nimrods also lists @masonthames as his Instagram account.
His Instagram has become another way for fans to follow his career outside movie releases. Posts have included professional appearances, travel photos, behind-the-scenes moments, and updates connected with his work.
For example, a January 2026 Instagram post was publicly documented from the @masonthames account.
Because social media usernames can change and impersonator accounts exist, fans should check for verification and cross-reference an account with reliable film or production sources before assuming it is authentic.
Mason Thames age 2026
Mason Thames is 19 years old in 2026. His date of birth is July 10, 2007, so he turned 19 on July 10, 2026.
His age is especially interesting because many audiences first saw him when he was much younger in The Black Phone. The difference between his early roles and his more recent work reflects several years of natural growth and professional experience.
At 19, Thames has already worked across several genres and with established actors. His 2025 film slate included How to Train Your Dragon, Black Phone 2, and Regretting You, while his credits also include Incoming, Monster Summer, and Nimrods.
Mason Thames height
Mason Thames’ exact height is not officially confirmed in a major studio biography. Current celebrity height sources generally place him around 5 feet 8 inches (172.7 cm), although other websites have published different figures.
For that reason, 5 feet 8 inches is best described as an estimate, not a verified measurement.
Height information about young actors can become especially inconsistent because older sources may have been published while the actor was still growing. Photography also isn’t a reliable way to determine someone’s exact height because footwear, camera angles, posture, and perspective can affect comparisons.
Mason Thames age in Black Phone
Mason Thames was born in 2007, while The Black Phone was released in 2021. That means he was 14 years old when the movie was released, although his exact age during filming depends on the production dates.
In the movie, Thames plays Finney Blake, a shy teenager who is abducted and held in a soundproof basement by the Grabber, played by Ethan Hawke. The character is younger than Thames was at the time, with Finney portrayed as a 13-year-old boy.
The role became the defining early performance of Thames’ career and introduced him to a much wider audience.
Mason Thames age in Black Phone 2
Black Phone 2 was released in 2025, with Thames returning as Finney. Since he was born on July 10, 2007, he was 18 years old when the sequel was released. IMDb lists the film among his 2025 acting credits.
The sequel gave audiences a chance to see Thames return to a character that had helped establish his career several years earlier. His real-life age had changed significantly from the first film, making the difference between the actor and his original teenage character more noticeable.
Mason Thames age in Incoming
Mason Thames was 17 years old when Incoming was released in 2024. He played Benj Nielsen in the Netflix teen comedy, which follows a group of incoming high school freshmen dealing with the chaos surrounding their first big party.
The movie showed a different side of Thames compared with his serious horror performance in The Black Phone. Instead of playing a frightened teenager trapped in a dangerous situation, he took on a lighter comedy role focused on teenage friendship and awkward social experiences.
That contrast helped demonstrate the range of roles he was beginning to explore.
Mason Thames birthday
Mason Thames’ birthday is July 10. He was born on July 10, 2007, in Dallas, Texas.
His birthday means his age changes each year in the middle of July. He turned 18 on July 10, 2025, and celebrated his 19th birthday on July 10, 2026.
The date is useful when checking older articles about him because many biographies can become outdated quickly. For example, a page describing Thames as 17 or 18 may have been accurate when published but no longer reflects his current age.
Mason Thames movies
Mason Thames has built a growing filmography despite being only 19 in 2026. His movie credits include horror, comedy, fantasy, and drama, giving him experience across several different genres.

Mason Thames’ career is notable because he has continued moving into different types of roles rather than being identified with only one genre. His journey from Finney Blake in The Black Phone to Hiccup and other leading roles shows how quickly his professional opportunities have expanded.
Final Thought
For anyone searching Mason Thames age, the key detail is that he is 19 in 2026, but his career already stretches back many years. Born in 2007, he began performing young, trained in ballet, entered television, and eventually became known worldwide through The Black Phone.
His current filmography includes major studio projects alongside smaller productions, giving fans a clear picture of an actor who has grown considerably since his breakthrough. His exact height remains an estimate, while his July 10 birthday and 2026 age are well documented. As his movie career continues, those early roles provide useful context for understanding just how young he was when he first reached a national and international audience.
