The New Era: Post-Sheldon Projects and Career Pivot
After dedicating nearly a decade to the character of Sheldon Cooper, Armitage is making calculated moves to define his career's next phase. Rather than jumping immediately into another long-term series, his current projects suggest a desire for variety, challenging roles, and a pivot towards more mature, high-concept material.
1. The Adam Trials: A Major Sci-Fi Thriller Role
Perhaps the most exciting and significant new project for Armitage is the psychological thriller film, The Adam Trials. This marks his first major live-action film role since 2017 and a stark departure from the family-friendly comedy of Young Sheldon.
The film is described as a psychological thriller with a science-fiction twist, centering on a man (played by Martin Freeman) who undergoes a radical experimental procedure to confront his personal demons. Armitage is confirmed to star alongside Freeman, a veteran actor known for his roles in The Hobbit and Sherlock.
This project is crucial for Armitage’s career, as it allows him to shed the "child prodigy" image and tackle a role that will undoubtedly require a different kind of intensity and dramatic depth. Working opposite an actor of Martin Freeman's caliber will also provide a masterclass in screen performance, solidifying his transition into more adult-oriented cinema.
2. A Surprising CBS Return: Guest Starring on Ghosts
In a delightful and unexpected twist, Armitage is set to return to the CBS network, the long-time home of Young Sheldon, with a guest-starring role in Season 5 of the hit comedy series Ghosts.
The appearance is scheduled for an upcoming episode, rumored to air in April 2026, and is particularly unique because Armitage will be playing a "heightened version of himself." This type of meta-humor allows him to directly address his fame and the legacy of Sheldon Cooper in a fresh, self-aware, and comedic way.
While only a guest spot, this role keeps him connected to the network and allows him to showcase his comedic timing outside the confines of his iconic character, proving his versatility and willingness to have fun with his public persona. It’s a smart, low-pressure way to re-enter the television landscape.
The Foundational Roles: Why His Early Work Still Matters
Before he became a household name as Sheldon Cooper, Iain Armitage had already built a remarkable resume working with Hollywood heavyweights. These foundational roles are essential viewing for any fan wanting to understand his range and topical authority.
3. Big Little Lies (2017–2019): The Dramatic Breakthrough
Armitage’s first major role was as Ziggy Chapman, the son of Shailene Woodley’s character, Jane, in the critically acclaimed HBO drama Big Little Lies. This role was a dramatic powerhouse, requiring him to portray a child struggling with bullying, a complicated family life, and eventually, the revelation of his parentage.
His performance as Ziggy was a masterclass in conveying emotional turmoil and vulnerability, earning him early critical praise and proving his dramatic chops long before Young Sheldon premiered. The series also provided him with the invaluable experience of working alongside A-list stars like Reese Witherspoon, Nicole Kidman, and Laura Dern.
Topical Authority Note: There is significant buzz and speculation regarding a potential Season 3 of Big Little Lies. Should the series move forward, a return for Armitage as Ziggy Chapman would be a highly anticipated event, bridging his early career with his current trajectory.
4. Our Souls at Night (2017): Working with Legends
In the romantic drama film Our Souls at Night, Armitage played Jamie, the grandson of Jane Fonda’s character. The film, which also starred Robert Redford, saw Armitage hold his own alongside two Hollywood legends. His character was central to the emotional core of the story, providing a catalyst for the main relationship.
5. The Glass Castle (2017): A Gritty Memoir
Based on the memoir by Jeannette Walls, The Glass Castle saw Armitage take on the role of the younger version of Brian Walls. The film, which explored a dysfunctional and nomadic family life, further demonstrated Armitage’s ability to handle complex and emotionally raw material in a feature film setting.
Iain Armitage's Voice Acting Success
Beyond live-action, Armitage has established a strong presence in the world of voice acting, ensuring his voice is recognizable even when his face isn't on screen. This work highlights his ability to convey character and emotion using only his vocal talents.
6. The PAW Patrol Franchise (2021, 2023): Chase
Armitage took over the voice role of Chase, the German Shepherd police dog and one of the main protagonists in the PAW Patrol franchise, for the major animated feature films, including PAW Patrol: The Movie (2021) and PAW Patrol: The Mighty Movie (2023). This role cemented his status in the animation world and introduced him to a new generation of younger fans.
7. Scoob! (2020): Young Shaggy Rogers
In the animated Scooby-Doo origin story, Scoob!, Armitage provided the voice for the younger version of Shaggy Rogers. This performance showed his ability to capture the essence of a classic, beloved cartoon character, adding another layer to his versatile filmography.
Iain Armitage’s career is currently in an exciting state of flux. While he continues to enjoy personal interests like his passion for flying, his upcoming roles in The Adam Trials and Ghosts signal a deliberate and intriguing pivot.
