Isla Gie Wiki

Isla Grace Gie, professionally known as Isla Gie, is a British actress originally from the United Kingdom and is of half South-African heritage on her mother’s side. She began her stage career in 2018, performing in the UK and Ireland tour of Les Misérables as Young Éponine, later also playing Little Cosette. The following year, at the age of 8, she played the lead role of Cindy-Lou Who in the UK premiere tour of Dr. Seuss’ How the Grinch Stole Christmas! The Musical, performing across multiple cities including London, Manchester, Edinburgh, Salford, and Birmingham.

Her major West End breakthrough came in 2022, when she was cast as Matilda Wormwood in the Royal Shakespeare Company’s production of Matilda the Musical at the Cambridge Theatre. She held the role from March to September 2022, performing a total of 62 shows as Matilda and serving as standby for another 56. Notably, she was the first Matilda in the production to perform the Mafia scene in Bulgarian, after the show switched the language away from Russian in the week before her debut.

Her television career began in 2021 with the BBC and Amazon Prime comedy series The Outlaws, in which she played Holly, the granddaughter of Frank (played by Christopher Walken), directed by Stephen Merchant and John Butler. She has since built an impressive list of credits including:

She trains at Harrow Gymnastics Club and has competed at her first British Championships, after which she was invited to trial for and successfully gained a place on the GB Aspire Squad and the Scotland PPP Squad. She combines her stage and screen work with serious physical training, which has given her the kind of discipline, coordination, and stage presence that few young actors her age can match.

Isla Gie as Tali in NCIS: Tony & Ziva

Isla’s most prominent role to date is Tali DiNozzo, the daughter of Tony DiNozzo (Michael Weatherly) and Ziva David (Cote de Pablo), in the Paramount+ spin-off series NCIS: Tony & Ziva. Her casting was officially announced in July 2024, with production beginning in Budapest shortly afterward. The series premiered on September 4, 2025, with three episodes dropping at once and subsequent episodes released weekly through the season finale on October 23, 2025.

The show was a milestone for the NCIS franchise as the first NCIS series to feature a child actor in a lead role, and Isla’s casting was seen by both producers and franchise fans as a critical creative decision. Cote de Pablo and Michael Weatherly, who also served as executive producers, were vocal in their praise for her work, with de Pablo describing her as “perfect for the show” and consistently engaged in the craft. The series holds an 82% approval rating on Rotten Tomatoes based on 11 critic reviews.

On December 19, 2025, Paramount+ confirmed that NCIS: Tony & Ziva would not return for a second season, ending Isla’s run on the show after one season. Despite the cancellation, the role brought her substantial new international recognition and significantly expanded her audience beyond the UK.

Isla Gie Personal Life and Interests

Outside her acting and athletic pursuits, Isla has spoken publicly about her love of singing and her broader interest in performance as a whole, not just acting. She is also reportedly taking flight lessons, an unusual hobby that speaks to the same curiosity and ambition that characterizes her professional work. She has expressed enthusiasm for the physical demands of certain roles, including prosthetic work in Villain and the unconventional setups required for some of her TV scenes.

Her favorite song to perform during her Matilda run was “Quiet,” which she has described as deeply powerful because of the moment of stillness it creates with the audience. She has cited the opening night of Matilda the Musical at the Royal Shakespeare Company as one of the best days of her life, particularly because she had watched the same production at age 4 and had been singing the songs ever since.

• Selection to the Scotland PPP Squad (2024)
