Early Life and Education

Isabelle Nélisse was born on December 3, 2003, in Windsor, Ontario, Canada, to Hugues Nélisse, an engineer specializing in acoustics, and Pauline Belhumeur, a former schoolteacher who later managed the careers of Isabelle and her sister Sophie.

At age four, the family moved to Montreal, Quebec, where Isabelle grew up alongside her older sister, Sophie Nélisse, a fellow actress known for The Book Thief, and older brother, Vincent Nélisse.

Isabelle’s interest in acting was sparked by her siblings; Vincent initially wanted to act, leading their mother to sign both Sophie and Isabelle with a talent agency. The family’s French-Canadian heritage and supportive environment fostered Isabelle’s early career.

Details about her formal education are limited, but she likely attended schools in Montreal while balancing acting roles, possibly with on-set tutoring due to her early start in the industry at age eight.

Career

Isabelle Nélisse began her acting career at age eight with a role as Chloé, fille de Daniel, in the Canadian drama series Mirador (2010). Her breakthrough came in 2013 with the horror film Mama, directed by Andy Muschietti, where she played Lilly, a feral child, alongside Jessica Chastain and her sister Sophie, who played Annabel. The role earned her critical praise and a nomination at the Young Artist Awards.

That year, she also appeared in Whitewash as Chloe. In 2014, she played Emma Arnot in three episodes of the FX horror series The Strain and had a minor role in Mommy, directed by Xavier Dolan.

In 2016, she starred as Mary in Wait Till Helen Comes (also known as Little Girl’s Secret), a horror film co-starring Sophie Nélisse. In 2017, she played Judith in It, another Muschietti-directed horror film, and appeared in Et au pire, on se mariera (Worst Case, We Get Married) as Aïcha.

Her most notable role came in 2018 as Jenny in The Tale, an HBO drama about childhood sexual abuse, where her performance opposite Laura Dern was lauded for its emotional depth. Her final credited role is in Dérive (The Far Shore, 2018) as Mélissa.

Since 2018, no new acting projects have been documented, suggesting a possible hiatus or shift in focus, though her agency, Agence M, still lists her as an active client.
