Mason Thames

At just 19, Mason Thames has already carved out a distinctive space in Hollywood. He stepped onto the global stage as Finney Blake in the 2021 horror phenomenon The Black Phone, a performance that earned widespread critical praise for its emotional depth and raw intensity. Since then, the young actor has continued to build a filmography that suggests a career with serious staying power, moving from period horror to science fiction and preparing to take on one of animation’s most beloved characters in a live-action adaptation.

Born on July 10, 2007, Thames is a product of the digital age, but his on-screen work recalls a more classical approach to acting. He has worked alongside veterans like Ethan Hawke and is now stepping into the shoes of Hiccup for a live-action How to Train Your Dragon. For audiences tracking the next generation of leading men, Mason Thames represents a compelling case study in early, focused success.

Who is Mason Thames? Age, Bio, and Early Life

Mason Thames was born in the United States and began his acting career relatively early. His first credited role came in 2017 on the television series The Fosters. This marked the beginning of a steady climb through guest appearances and smaller projects, including the 2019 short film The UFO Project. While his early work was modest, it provided the foundational experience he would need for a breakout role.

Confusion exists around his parents’ names. Multiple sources list his parents as Chad Thames and Elizabeth, while others suggest Byron Thames and Lisa Alpart. Because these records conflict, and his family has largely stayed out of the public eye, the information remains unverified. What is clear is that Thames keeps his personal life separate from his public persona, a choice that has fueled fan curiosity without yielding definitive answers.

Mason Thames Height and Physical Profile

One of the most frequently searched questions about Thames concerns his height. Across multiple biography sites, the most consistently reported figure is 5 feet 7 inches (approximately 170 cm). Some sources stretch this to 5’8″, while one outlier lists 5’3″. The 5’7″ figure appears the most reliable, as it is the median and most frequently repeated measurement.
