He first attracted public attention through his YouTube series Iain Loves Theatre, in which he reviewed Broadway and off-Broadway productions. Beyond television, Armitage has appeared in feature films and provided voice work for major animated projects, establishing himself as one of the most recognizable young performers in contemporary Hollywood.
Born in Savannah, Georgia, Armitage grew up in a family deeply connected to the performing arts and public service.

His early immersion in theater, combined with disciplined home study, helped him move smoothly from online reviews to professional acting opportunities.
Early Life and Background
Iain Armitage was born on July 15, 2008, in Savannah, Georgia. He is the son of Euan Morton, a Scottish actor known for his work on Broadway, and Lee Armitage, an American theater producer. His maternal grandfather is Richard Lee Armitage, who served as United States Deputy Secretary of State, giving the family a blend of artistic and public-service roots that shaped Armitage’s upbringing.
From a young age, Armitage was surrounded by the world of live performance. His parents’ involvement in theater exposed him to musicals, plays, and the wider New York and regional theater scenes. This environment nurtured his enthusiasm for reviewing productions, an interest that eventually grew into the YouTube series Iain Loves Theatre, where his thoughtful commentary on Broadway shows gained a wide following and brought him to the attention of industry professionals.
Armitage is homeschooled, a structure that has allowed him to balance rigorous academics with professional acting commitments. He has also studied multiple languages to varying degrees, including Russian, Armenian, German, Spanish, Italian, Assyrian, and Sinhalese, demonstrating a curiosity that extends well beyond the stage and screen.
Path to Acting
Armitage’s entry into entertainment began online. His Iain Loves Theatre videos impressed theater insiders for their depth and clarity, and the series’ popularity led agents and producers to take notice. In 2015, his online profile earned him an invitation to serve as a correspondent for entertainment personality Perez Hilton during the 2015 Tony Awards, an appearance that was even acknowledged in the ceremony’s opening number.
The recognition from his theater reviews quickly translated into professional opportunities. In January 2017, Armitage guest-starred in the Law & Order: Special Victims Unit episode Chasing Theo, playing a kidnapped child in a dramatic television role. That same year, he joined the HBO drama Big Little Lies as Ziggy Chapman and appeared in the feature film The Glass Castle, an adaptation of Jeannette Walls’ memoir.
These early performances positioned Armitage for the role that would define his career. In March 2017, he was cast as the young Sheldon Cooper in Young Sheldon, a single-camera comedy on CBS that ran from 2017 to 2024. The casting marked his transition from internet theater critic to a leading young actor on a major American television series.
