For years, audiences watched Iain Armitage grow up on television. First as the quiet, sensitive Ziggy in Big Little Lies, then as the brilliant young genius at the center of Young Sheldon, Armitage became one of the rare child actors whose career unfolded in public without losing its sense of warmth.
Now, with Young Sheldon officially over, the teenage actor is stepping into a quieter chapter — one shaped less by studio schedules and more by family time, flying lessons, and the uncertainty that comes after growing up on screen.
It’s a transition many young performers never really get the chance to experience slowly. Armitage, though, appears to be doing exactly that.
A childhood spent around stories
Long before network television, Armitage was already comfortable in the spotlight.

He first gained attention through his YouTube channel Iain Loves Theatre, where he reviewed Broadway productions with an enthusiasm that felt genuine rather than rehearsed. The videos eventually led to appearances on red carpets and interviews with major theater stars at the Tony Awards.
Entertainment was already part of family life. His father, Euan Morton, is a respected stage actor, while his mother, Lee Armitage, works as a producer.
That background helped introduce Armitage to the industry early, but his breakout came quickly. At just seven years old, he was cast as Ziggy in Big Little Lies, the HBO drama that became one of television’s biggest cultural moments in 2017.
The series earned 16 Emmy nominations in its first season and later returned for a second run, with Armitage reprising his role alongside stars including Nicole Kidman and Reese Witherspoon.
Becoming television’s young Sheldon
That same year, Armitage landed the role that would define much of his childhood.
In Young Sheldon, the prequel to The Big Bang Theory, he played a younger version of Sheldon Cooper — socially awkward, intellectually gifted, and often misunderstood in his small Texas town.
The series ran for seven seasons and 141 episodes before ending on May 16, 2024.
For viewers, the finale marked the end of a familiar comfort show. For Armitage, it marked the end of a routine that had shaped much of his adolescence.
In interviews around the finale, he spoke warmly about the cast and crew, describing them less as coworkers and more as an extended family. That feeling seems to have lasted beyond production.
Over the past year, Armitage has continued sharing moments with former co-stars including Jim Parsons, Ed Begley Jr. and Wallace Shawn.
He also reunited in late 2024 with actresses who played his television mothers — Zoe Perry from Young Sheldon and Shailene Woodley from Big Little Lies.
Armitage later credited Woodley with helping him feel safe and comfortable when he first joined the HBO series as a child. He said the positive atmosphere on set played a major role in convincing him to continue acting professionally.
Life after a hit show
Since Young Sheldon wrapped, Armitage has largely stepped away from major acting commitments.
Instead, he has been focused on aviation.
In late 2024, he revealed that he had earned a student pilot’s license and hoped to qualify for a private pilot’s license once he turned 17. He described flying as something that brought him joy while spending time in Los Angeles between auditions.
The shift may seem unexpected for a teenager known primarily through television, but it also reflects a growing pattern among young actors seeking balance after years in the public eye.
Rather than rushing immediately into another long-running project, Armitage appears to be allowing space for a more ordinary kind of adolescence — one not entirely defined by cameras or production schedules.
He has still remained connected to Hollywood in smaller ways. In 2026, he appeared as himself in an episode of the CBS comedy Ghosts, playing a heightened version of himself during a poker game storyline at the show’s mansion setting.
No future starring projects have been publicly announced.
The possibility of returning to Monterey
Even without a confirmed next role, Armitage may eventually return to one of the projects that launched his career.
Development on a third season of Big Little Lies continues to move forward, according to Kidman and Witherspoon. Author Liane Moriarty is once again involved creatively.
In March 2026, Moriarty announced a new novel titled Big Little Truths, which is expected to provide the foundation for the upcoming season.
For longtime viewers, the possibility of seeing the original cast together again carries a certain emotional weight. Many of the child actors from the series are now young adults, and revisiting those characters years later could give the story an entirely different tone.
Whether Armitage returns to Monterey or heads somewhere completely new, his career already stands apart from many former child stars. Much of that may come down to timing, support systems, and the fact that he never seemed pushed to grow up too quickly.
For now, he appears content living somewhere between two worlds — still connected to acting, but also discovering who he is outside of it, thousands of feet above the ground.
