How Old Is Mason Thames?
If you were born in 2007, you likely spent your childhood watching Mason Thames on a screen somewhere. He started acting at just 10 years old, but it was his 2022 performance as Finney Blake that turned him from a working child actor into a genre icon. Now, he’s stepping into the boots of a franchise legend, and the pressure is on.
The English Wikipedia entry states: “Mason Thames (born July 10, 2007) is an American actor.”
What’s often tricky is that the internet doesn’t agree on the basics. Some biographies say he’s from Dallas, others say Phoenix. His height is listed as both 5’7″ and 5’9″ depending on who you ask. This guide doesn’t just give you the numbers; it shows you the receipts, explains the discrepancies, and tells you which sources are most reliable when it comes to his personal stats and filmography.
The internet has a habit of turning trivia into a guessing game. For Mason Thames, the most significant discrepancy lies in where he was born and how tall he is. According to the English and Portuguese Wikipedia pages, he hails from Dallas, Texas. However, several celebrity biography sites claim Arizona. Similarly, his height fluctuates by about two inches depending on the source you check.
What Is Mason Thames’ Height and Other Personal Details?
- Birthdate: July 10, 2007 (confirms he is 17 as of 2025).
- Birthplace (Wiki): Dallas, Texas, U.S.
- Birthplace (Alt): Phoenix, Arizona, USA (per some celebrity bios).
- Height (Wiki/Alt): 5’8″ (1.73 m).
- Height (Rumor): Ranges from 5’7″ to 5’9″ across other bio sites.
Screen Dollars confirms: “Mason Thames was born on July 10, 2007, making him 19 in 2026.”
The trustworthiness of this data breaks down by source type. The Wikipedia portal provides the foundation, but even its entry acknowledges variance. A celebrity data aggregator (BiographyKind) lists the height as 5’7″, while a separate biography site (BiographyKind) claims 5’9″.
Because he is a minor, his management is notoriously strict about releasing personal measurements. This has led to a vacuum where fan-edited wikis and low-tier gossip sites fill in the gaps with estimates. The core metric to remember is that official sources remain silent; the 5’8″ figure is an approximation based on visual comparison with co-stars, not a published stat.
The implication: readers should treat height figures as estimates until official sources release measurements.
Is Mason Thames in a Relationship?
There is no confirmed public information about Mason Thames being in a relationship. Speculation, particularly about a possible connection with McKenna Grace, has circulated online but remains unverified. He has not been married, and his dating history is not disclosed.
Who Is Mason Thames’ Father?
Mason Thames’ father is not identified in any credible public source. Wikipedia lists only his birth and career, omitting parent details. The actor has kept his family life intensely private.
What Movies Has Mason Thames Starred In?
Mason Thames’s career trajectory is more defined than his birth certificate. He began with a role in a short film and quickly moved into television before his movie star turn. Here is how his credits stack up, according to the Internet Movie Database (Filmography portal).
Credited Screen Entries
- 2017 – After Omelas: An early short film credit that kicked off his career.
- 2021 – The Black Phone: His breakout as Finney Blake (though filmed in 2021, it released widely in 2022).
- 2024 – Incoming: A Netflix comedy where he plays Benj Nielsen, showcasing his range beyond horror.
- 2025 – How to Train Your Dragon: The live-action remake where he voices Hiccup Horrendous Haddock III.
There is a persistent rumor that he had a recurring role in the Apple TV+ series For All Mankind. One celebrity lifestyle magazine (Healthy Celeb) mentions this, but the main Wikipedia filmography does not list it among his screen credits. This suggests either a very early, uncredited background role or an error propagated across the web.
The pattern: secondary sources may inflate his filmography, so IMDb and Wikipedia remain the most reliable check.
What’s Next: The Dragon Franchise and Beyond
His upcoming schedule is what separates him from other teen actors. The live-action How to Train Your Dragon is a massive risk and an even bigger opportunity.
The Stakes of Hiccup
Taking over a role voiced by Jay Baruchel is a tall order. The trailers released in late 2024 show Thames with a thick Scottish accent, a departure from his natural American tone. Early reactions to The Black Phone proved he can carry a film’s emotional weight, but a franchise of this scale demands a different kind of star power.
His current Instagram following sits at over 3 million, a number that will likely swell significantly once the film hits theaters in June 2025. For now, he remains relatively low-key compared to his Disney Channel peers, often focusing on press tours rather than personal brand drama.
The critical question is whether he can transition from “horror kid” to “action lead.” His performance as Hiccup will tell us if he’s a one-hit-wonder or a A-list mainstay. The casting directors clearly love him—he secured this role just two years after his breakout—but the audience will have the final say.
