Notable roles and where to find them
McCormack’s largest television role to date is Alison in Netflix’s Everything Now, a coming-of-age drama that ran for eight episodes in 2023. That same year she appeared as Rouge Contestant in Dungeons & Dragons: Honor Among Thieves, the fantasy heist film that brought the tabletop role-playing game to a wide mainstream audience.
In The Witcher, Netflix’s adaptation of Andrzej Sapkowski’s novels, she played the elven sorceress Lara Dorren in a single episode. The part carries weight within the series’ mythology, as Lara Dorren is a significant figure in the show’s backstory. Her filmography also includes a 2022 episode of Disney+’s Willow, the film The Magic Flute (2022), and the thriller Witness Number 3.
More recently, she has a supporting role as Teen Wendy in the six-episode series Small Town, Big Story (2025). A complete picture of her credits can be found on her IMDb profile, which lists both released and upcoming projects. Readers interested in detailed filmography guides may also find the coverage of Dominic Cooper Movies and TV Shows – Complete Filmography Guide 2025 useful for comparing career trajectories.
House of Guinness and the role of Ellen Cochrane
McCormack’s most high-profile role to date is Ellen Cochrane in the Netflix series House of Guinness, set in the late 1860s and centred on the rise of the Guinness brewing dynasty. According to Screen Daily, her character is described as one of the leaders of the Irish Republican Brotherhood (IRB). The series, which also stars James Norton, is expected to release in 2025 and has already generated significant industry buzz.
House of Guinness marks McCormack’s first lead role in a major period drama. Playing a political operative within the IRB places her character at the intersection of the Guinness family story and the broader historical currents of 19th-century Ireland. The series is produced by Netflix and has been described by Screen Daily as a key project for her career trajectory.
Who is Niamh McCormack’s partner?
Based on available public records and media coverage, there is no confirmed information about Niamh McCormack’s current relationship status or partner. The articles and interviews that document her career focus on her professional work, her training, and her upcoming projects. No reliable source has published details about a romantic partner.
This absence of information is common for actors who are early in their careers and who have not chosen to discuss their private lives in interviews. McCormack’s public profile, as reflected in the coverage from Screen Daily, IMDb, and her management agency, is almost entirely professional in nature.
Are Niamh McCormack’s lips real?
Questions about whether McCormack’s lips are natural have circulated in online spaces, but no authoritative or medical source has addressed this topic. There is no statement from McCormack herself, no medical documentation, and no credible media report that confirms or denies any cosmetic procedure. This question remains in the realm of public speculation and cannot be verified from the available evidence.
No reliable source — including industry publications, official biographies, or McCormack herself — has provided information about cosmetic procedures. Claims about her lips being “real” or otherwise are not supported by any verifiable evidence and should be treated as speculation.
How old is Niamh McCormack?
According to her Wikipedia entry, Niamh McCormack was born on 17 January 2001, which makes her 24 years old as of 2025. Some databases have previously listed her birth year as 1995, but the 2001 date is the one used in her primary biographical sources. Given the discrepancy, the 2001 date is the more consistently cited figure in recent profiles.

Why is Niamh McCormack considered a rising star in 2025?
The label “Rising Stars Ireland 2025” applied by Screen Daily reflects both the quality of McCormack’s recent work and the industry anticipation surrounding House of Guinness. Her career has moved from small roles in established fantasy franchises to lead parts in Netflix’s most anticipated historical dramas, all within about six years.
Her ability to work across genres — fantasy, comedy, period drama, and coming-of-age television — has made her a versatile talent in a competitive market. The fact that she is also developing her own writing projects suggests a long-term approach to her career that extends beyond acting alone.
Public interest in her personal life, particularly around her relationship status and physical appearance, mirrors the typical curiosity directed at young actors experiencing a rise in visibility. However, the available evidence base for those topics remains thin, and McCormack herself has not engaged publicly with those questions.
