Alisha Weir is an Irish actress who has rapidly ascended to international stardom, best known for her titular role in Roald Dahl's Matilda the Musical (2022) and her captivating performance in the horror-thriller Abigail (2024). Her filmography spans musical theater, voice acting, dark comedy, and supernatural horror, showcasing a versatile "triple-threat" skill set.
As of 2026, Alisha Weir is recognized as one of the most promising young talents in the global film industry. After a meteoric rise that began in Dublin’s theater scene, she has successfully transitioned from a child prodigy to a formidable leading actress capable of anchoring big-budget studio productions and indie darlings alike. This guide explores her career trajectory, detailed filmography, and the specific roles that defined her path to the top of the "ones to watch" lists in Hollywood.
The Breakout: Roald Dahl's Matilda the Musical (2022)
The definitive turning point in Alisha Weir’s career came with her casting as Matilda Wormwood in the film adaptation of the stage musical. Directed by Matthew Warchus and released globally on Netflix (and theatrically in the UK and Ireland), the project was a massive undertaking that required a lead who could act, sing, and dance with professional precision.
Casting and Preparation
Weir was selected from thousands of young girls who auditioned for the role. At just 11 years old during filming, she had to navigate the immense pressure of following in the footsteps of Mara Wilson (the 1996 film Matilda) and the various stage actresses who won Olivier and Tony awards. Her preparation involved rigorous vocal coaching and choreography rehearsals for complex numbers like "Naughty" and "Quiet."
Impact and Critical Reception
Critically, Weir was lauded for bringing a "fierce intelligence" and "steely resolve" to the character. Unlike previous iterations, her Matilda felt grounded in a modern sensibility—less of a whimsical child and more of a revolutionary. This role earned her several award nominations, most notably a nomination for the Irish Film and Television Awards (IFTA) for Best Actress in a Lead Role, establishing her as a serious dramatic contender.
Expanding the Range: Abigail (2024)
If Matilda established Weir as a musical star, the 2024 film Abigail proved her range in the horror genre. Directed by Matt Bettinelli-Olpin and Tyler Gillett (the duo known as "Radio Silence"), the film follows a group of kidnappers who discover that the 12-year-old girl they have snatched is actually a bloodthirsty vampire ballerina.
Navigating the Horror Genre
In Abigail, Weir had to balance the facade of a terrified victim with the physical intensity of a predatory monster. The role required significant stunt work and the ability to perform ballet while covered in practical blood effects. Her performance was frequently cited as the highlight of the film, with critics noting her ability to switch from vulnerable to terrifying in a single frame.
Genre-Bending Success
The film was a critical success within the horror community, praised for its campy tone and innovative take on the vampire mythos. For Weir, it served as a successful "pivot" role, ensuring she would not be typecast solely in family-friendly or musical roles as she aged into her mid-teens.
Early Career and Irish Roots
Before her international breakout, Alisha Weir built a solid foundation in the Irish entertainment industry. Born in 2009 in Dublin, she was active in local theater and television from a very young age.
- Darklands (2019): In this gritty Irish crime drama, Weir played the role of Laura. While a supporting role, it provided her with early experience on a professional TV set, dealing with more mature themes than typical child-acting roles.
- Don't Leave Home (2018): This was Weir’s first foray into the horror/thriller genre. In this indie film, she played Siobhan. The film follows an American artist who travels to Ireland to investigate an urban legend, and Weir's performance, even at a very young age, showed an innate comfort with unsettling narratives.
- Two by Two: Overboard! (2020): Also known as Ooops! The Adventure Continues..., this animated feature saw Weir providing the voice for Primrose. Voice acting requires a different set of technical skills—relying entirely on inflection and tone—which further diversified her professional portfolio.
Collaboration with Elite Talent: Wicked Little Letters (2023)
In the 2023 dark comedy Wicked Little Letters, Weir played Nancy Gooding, the daughter of Rose Gooding (played by Jessie Buckley). This project was significant because it placed Weir alongside Academy Award-winning and nominated actors like Olivia Colman and Jessie Buckley.
Working on a period piece (set in 1920s Littlehampton) required Weir to adapt to a different linguistic style and historical context. The film revolves around a scandal involving anonymous, profanity-laden letters, and Weir’s performance added a layer of grounded familial stakes to the chaotic comedy. Being part of such a high-caliber ensemble cast solidified her reputation as a reliable professional capable of holding her own against the industry's best.

Acting Style and Technical Prowess
Industry analysts often point to Alisha Weir’s "emotional maturity" as her defining technical trait. Unlike many child actors who rely on "stageiness" or exaggerated expressions, Weir utilizes a more internal, cinematic approach.
- Vocal Control: Her background in musical theater (specifically at the Billie Barry Stage School in Dublin) provided her with exceptional breath control and pitch accuracy. This is evident not just in her singing, but in her ability to maintain consistent accents—such as the specific English regional accents required for Matilda and Wicked Little Letters.
- Physical Acting: In Abigail, the choreography wasn't just about dance; it was about "creature work." Weir had to learn how to move with an animalistic, supernatural speed while maintaining the poise of a ballerina. This level of physical commitment is rare for actors her age.
- Presence: Weir possesses what directors call "eyes that tell a story." In the quieter moments of Matilda, her ability to convey isolation and resilience without dialogue was what ultimately sold the performance to global audiences.
