Sermon’s breakthrough came with Jurassic World: Fallen Kingdom, released in 2018. She was selected to play Maisie Lockwood after a large casting search for the character. Production information has reported that thousands of young actors were considered during the casting process.

The role was especially significant because it became Sermon’s feature-film debut. Instead of starting with small background roles, she immediately entered one of the world’s biggest film franchises alongside established actors such as Chris Pratt and Bryce Dallas Howard.

In Jurassic World: Fallen Kingdom, Sermon plays Maisie Lockwood, a young character connected to the mysterious Lockwood family. Her performance introduced audiences to a character who became increasingly important to the story.

While promoting Jurassic World Dominion, Sermon was also continuing her education and was reported to be sitting her GCSEs around that period. This meant she was balancing school responsibilities with the demands of working on a major film production.

Her career has also expanded beyond the Jurassic World films. In 2023, she contributed to the BBC Radio 4 audio drama People Who Knew Me, showing an interest in work outside traditional feature films.

Isabella Sermon’s acting career may still be relatively young, but she has already worked on major international productions. After making her feature-film debut in Jurassic World: Fallen Kingdom, she returned for Jurassic World Dominion and later explored audio drama. Her career has continued to develop beyond the dinosaur franchise.

Isabella Sermon and Jurassic World

Sermon’s biggest career milestone remains her portrayal of Maisie Lockwood in the Jurassic World franchise. She won the role for Jurassic World: Fallen Kingdom after a major casting process involving more than 3,000 young actors in the UK and United States.

The 2018 movie introduced audiences to Maisie, a mysterious young girl connected to the Lockwood family. Sermon’s performance marked her professional feature-film debut and placed her alongside established stars including Chris Pratt and Bryce Dallas Howard.

Her involvement with the franchise continued with Jurassic World Dominion, released in 2022. In the film, Sermon played Maisie again and also portrayed the younger Charlotte Lockwood.

Returning for Jurassic World Dominion

Returning to a major franchise after several years gave Sermon an opportunity to approach her character differently. She had grown considerably between the two productions and was able to take on more responsibility as an actress.

In interviews, Sermon has discussed how much she learned from working with the cast and crew. She also described the production environment as supportive and said that watching experienced actors helped her understand more about the entertainment industry.

The production of Jurassic World Dominion was also unusual because filming resumed during the COVID-19 pandemic. Sermon was part of a production that had to follow strict health and safety procedures when cameras started rolling again.

People Who Knew Me

After her work in the Jurassic World movies, Sermon moved into audio drama. In 2023, she worked on People Who Knew Me, a BBC Radio 4/BBC Sounds drama involving actress Rosamund Pike. Sermon voiced the character Claire in the production.

The project gave her an opportunity to explore performance in a different format. Unlike film, audio drama relies heavily on voice, emotion and delivery because the audience cannot see the actor’s expressions or physical performance.

She has also shared advice for aspiring performers, emphasizing the importance of giving full effort to whatever work they choose to pursue.
