Early Life: From Ballet to Film Sets
Thames was born in Dallas and raised in the McKinney–Prosper area of North Texas, where he grew up with his parents, Chad and Elizabeth, and his older sister, Brooke-Madison. His sister — a trained ballerina who went on to study at the Colburn Dance Academy in Los Angeles — pulled him into dance as a young boy. Thames trained in ballet for about four years, performed in productions of The Nutcracker, and was reportedly the youngest member of an international ballet company.
That training turned out to be a secret weapon. Directors have noted that Thames carries an unusual physical discipline for a young actor — the stillness and body awareness that ballet teaches are visible in his horror performances, where holding back matters as much as bursting out. At around age 11, he traded dance shoes for headshots and began auditioning, making his acting debut in the 2017 short film After Omelas.
Breakthrough: The Black Phone
Thames' big break came at 14 when he was cast as Finney Blake, the kidnapped teenager at the center of The Black Phone (2021), opposite Ethan Hawke as the masked villain the Grabber. The Scott Derrickson-directed horror film was a critical and commercial success, and Thames' terrified-but-resilient performance drew widespread praise — he won the Editor's Eyeball Award for the role.
The performance was no fluke. When the sequel Black Phone 2 arrived in 2025, Thames reprised Finney in a continuation that confirmed him as one of the rare child actors who can anchor a franchise. Around the same time, he had also appeared as Danny Stevens in Apple TV+'s acclaimed series For All Mankind, showing range beyond the horror genre.
Becoming Hiccup in How to Train Your Dragon
In 2025, Thames took the biggest swing of his career: playing Hiccup in Universal's live-action remake of How to Train Your Dragon. Casting a beloved animated character in live action is one of Hollywood's riskiest moves, but Thames' performance won over skeptics and audiences alike, earning him a Saturn Award nomination. The film's success cemented his jump from promising young actor to leading man, and a sequel, How to Train Your Dragon 2, was announced.
The same year also brought Regretting You, a romantic drama in which Thames took his first romantic lead opposite McKenna Grace — his Black Phone co-star, with whom he went public as a couple in April 2025.
What Is Mason Thames' Height and Appearance?
Thames is reportedly around 5 ft 10 in (178 cm) tall, though — like many young actors — his exact height has not been officially confirmed by a studio or verified source and should be treated as an estimate. He has brown eyes and light brown hair, and is known on Instagram as @masonthames.
What's Next for Mason Thames?
At 19, Thames has one of the most open runways in Hollywood. How to Train Your Dragon 2 is in the pipeline following the first film's success, and industry trackers list him attached to Dynamic Duo, a film slated for 2028. The arc of his career so far — horror breakout, franchise lead, romantic lead — suggests a deliberate strategy to avoid being typecast as "the horror kid." His cited influences, Timothée Chalamet, River Phoenix, and Heath Ledger, hint at ambitions beyond blockbusters: character-driven dramatic work alongside the tentpoles.
The other open question is his public relationship with McKenna Grace. Young Hollywood romances are famously fragile under the spotlight, but the pair have handled theirs with relative maturity, appearing together at premieres and sharing low-key moments on social media rather than courting tabloid drama.
Mason Thames' Net Worth
Mason Thames' net worth has not been publicly disclosed. Online fan sites publish estimates ranging from roughly $1 million to $5 million, but none of these figures comes from a reputable wealth tracker such as Forbes or Celebrity Net Worth, and the numbers vary too widely to be reliable. What is clear is that starring roles in major studio releases and their sequels have set him up well for a long career.

Thames Among Hollywood's Young Stars
Thames belongs to a generation of young actors who have moved from streaming and genre films to franchise leads in record time. Millie Bobby Brown made the same leap from child star to leading woman in her teens, while Jenna Ortega built a fortune on horror and streaming hits before turning 25. On the music side, fellow Gen Z breakout Jessie Murph shows how quickly young performers can command mainstream attention. Among his nearest peers, Thames cites actors like Timothée Chalamet — himself a former child actor turned franchise star with an estimated $25 million fortune — as an influence.
