Mason Thames: Hometown, Age, Movies & Pronunciation Guide

Age: 19 (born July 10, 2007) · Known For: The Black Phone (2022) · Upcoming: How to Train Your Dragon (2025)

Key facts at a glance

Eight rows, one pattern: the verified columns are all professional, while the personal blanks stay blank.

The pattern: the personal rows are either absent or explicitly marked as rumored; the professional rows carry the citations.

What is Mason Thames’ hometown?

The short answer: no reliable public record pins down a single hometown. The long answer is a lesson in how quickly unverified facts spread.

Early life and birthplace

• Wikipedia’s actor biography says Thames is an American actor and places his upbringing in Dallas, Texas, specifically McKinney, but it reads like a fan-summary rather than a primary record. (Wikipedia (actor biography))
• His IMDb page, by contrast, lists a birth date but no verified hometown. (IMDb (filmography database))

Family background

• No primary sources in the public record name his parents or siblings. The only family-adjacent detail that keeps appearing is the same Dallas/McKinney location claim. (Mason Thames’ biography site)

The pattern is: the closer to official information, the less there is. Until a primary source — an interview, a birth record, a verified profile — steps in, treat “Texas hometown” as a rumor, not a fact.

Who plays Hiccup in How to Train Your Dragon?

The casting list is one of the few rock-solid facts in Mason Thames’ public record. He’s the actor attached to play Hiccup in the live-action adaptation.

Casting announcement

• IMDb’s professional credits list Mason Thames as Hiccup in the live-action How to Train Your Dragon, directed by Dean DeBlois, with release plans pointing to 2025. (IMDb (filmography database))

Mason Thames’ other movies

• His breakthrough was playing Finney Blake in The Black Phone (2022). (Wikipedia (career summary))
• His IMDb filmography also includes For All Mankind, Incoming, Monster Summer, and the short After Omelas. (IMDb (filmography database))
• He also appeared as Young Walker in the CW series Walker and was attached to an Evel Knievel biopic that stalled during the pandemic. (Mason Thames’ biography site)

The implication: Hiccup is not a first shot at leading-man pressure — it’s the next escalation after a horror hit and a pile of smaller credits.

How do you pronounce Mason Thames?

It trips people up because the spelling looks like it should rhyme with “names,” but the traditional English pronunciation takes a different route.

Correct pronunciation of ‘Thames’

• The River Thames is conventionally pronounced “temz” — with a silent h and a short e, not “thay-mes.” (Wikipedia (river guide))
• Mason Thames’ surname, in bios and fan pronunciation guides, follows the same river pronunciation, so his full name sounds like “MAY-son temz.” (Wikipedia (actor biography))

Common mispronunciations

• Reading the h and the a as written gives “thay-mes” or “th-ames,” which is how newcomers almost always say it before they hear the river pronounced. (Wikipedia (river guide))

What this means: if you nail the pronunciation, you already sound more like someone who reads the credits than someone who just watches the trailer.

Is Mason Thames his real name?

Publicly, Mason Thames is the name that appears in casting lists, film reviews, and festival programs. Whether that matches a legal birth certificate is a separate, unanswered question.

Stage name vs birth name

• All credible professional listings — IMDb, Wikipedia, official biographies — use “Mason Thames” as his working name. (IMDb (filmography database))
• No source has published a different birth name or a formal stage-name announcement. (Wikipedia (actor biography))

Origin of the surname Thames

• The surname traces back to the river’s ancient name: the Latin Tamesis and the Old English form Temese. (Etymonline (etymology dictionary))
• Etymologists commonly connect the root to a word meaning “dark” or to the idea of flowing, but the exact origin is not settled. (Wiktionary (language reference))

The trade-off: the name gives him automatic memorability and a built-in trivia hook, but it also creates an expectation of a British heritage that no public record yet supports.

Why is Thames so famous?

Blame the river, not just Hiccup. The name Thames has been attached to one of Europe’s most important waterways for more than a thousand years.

History of the River Thames

• The River Thames is the longest river entirely in England, flowing through London and into the North Sea. (Wikipedia (river guide))
• Its Latin name, Tamesis, and its Old English form Temese show how the modern spelling slowly settled into “Thames.” (Etymonline (etymology dictionary))

Why it’s called Isis

• The section of the river passing through Oxford was historically referred to as Isis, a scholarly nickname that still appears in rowing contexts. (Wikipedia (river guide))

The French name for the Thames

• In French, the river is la Tamise, which follows the same Latin stem with a French twist. (Wiktionary (language reference))

The takeaway: the river was memorable before Mason Thames was born, and that’s exactly why his name works as a search phrase, a talking point, and a small piece of linguistic history.

Timeline: the career so far

Four entries, one trajectory: from short film debut to franchise lead in under a decade.

The pattern is fast and deliberate: horror to family dramedy to a fantasy franchise, with Hiccup as the clear commercial ceiling.

What we actually know — and what stays fuzzy

A quick reality check separates the verified from the recycled.

The balance is lopsided: the career is solid, the personal data is mostly shadow.

In their own words

Here are three statements from the sources that anchor this profile.

“Mason Thames, the 19-year-old actor out of the How to Train Your Dragon and Black Phone franchises, has inked a deal to star in Narcs.”

Mason Thames’ biography site

“Thames played Finney Blake in Scott Derrickson’s horror film The Black Phone.”

IMDb (filmography database)

“The River Thames name appears in Latin as Tamesis.”

Etymonline (etymology dictionary)

Three citations, one through-line: the actor’s name and the river’s name do the same work — getting you to click, remember, and maybe look up the etymology.

The final read

Mason Thames is a real actor with a verified filmography and a surname that turns every pronunciation guide into a trivia page. The catch is that the public knows him best through roles, not records: his hometown, height, and birth name are still unofficial. For How to Train Your Dragon fans, the practical question is easier — the actor playing Hiccup is Mason Thames, say it “MAY-son temz,” and wait for the first trailer. For anyone trying to verify his backstory, the choice is clear: trust the filmography over the fan wikis, or Mason Thames will keep having a Texas hometown that no primary source confirms.
