She is known for roles in Mortal Engines, The Kid, Animal Kingdom, Gonzo Girl, Disclaimer, The Beast in Me, and the 2026 series Love Story. She is also the daughter of actors Vincent D’Onofrio and Greta Scacchi, which gave her an early connection to the entertainment industry. However, George has gradually established her own identity as a performer rather than relying solely on her family’s reputation.
Born in Sydney, Australia, Leila George D’Onofrio grew up primarily in England and later studied acting in Australia, London, and the United States. Her education included training at Sydney Film School and the Lee Strasberg Institute in New York. These experiences gave her exposure to different approaches to acting before she began taking on professional roles.
George first attracted wider attention with projects such as Mother, May I Sleep with Danger? and Mortal Engines. Her career then took a major step forward with Animal Kingdom, where she played the younger version of Janine “Smurf” Cody, the character portrayed in the present-day storyline by Ellen Barkin. George’s performance became an important part of the show’s later seasons and gave her an opportunity to explore a complicated character over different periods of her life.
In recent years, she has continued expanding her television and film work. Her credits include Disclaimer, The Beast in Me, and Love Story. She is also part of the cast of Runner, an action thriller scheduled for theatrical release in September 2026.

Early Life and Family Background
Leila George was born in Sydney, New South Wales, Australia. She comes from a family deeply connected to acting because both of her parents are established performers.
Her father is American actor Vincent D’Onofrio, who has appeared in films and television productions including Full Metal Jacket, Law & Order: Criminal Intent, and Daredevil. Her mother is Italian-British actress Greta Scacchi, known for films such as Presumed Innocent, White Mischief, and The Player.
Despite being born in Australia, George spent much of her childhood in England. IMDb notes that she was raised by her mother in the Brighton area of East Sussex. Her early exposure to different countries and cultures later became useful as she developed a career that moved between Australian, British, and American productions.
Having famous parents naturally meant that George grew up around the entertainment world. Nevertheless, her career path involved formal acting education and training rather than simply entering the industry through family connections.
Leila George’s Education and Acting Training
George began developing her interest in acting at a relatively young age.
In 2008, she took acting classes at Brighton College. The following year, she attended Crawley College, which her mother had also attended. She later studied at Arts Educational Schools in London.
Her education then took her to Australia, where she studied at Sydney Film School in 2011. A year later, she moved to the United States and studied at the Lee Strasberg Institute in New York.
This international education is an important part of her background. Rather than limiting her training to one country, George experienced acting programs in England, Australia, and the United States.
That background also reflects the international nature of her later career.
Leila George’s Early Acting Career
George began appearing professionally during the 2010s. One of her early credited projects was Mother, May I Sleep with Danger?, a television film released in 2016.
The project gave her an opportunity to work in front of a larger American television audience. Although it was an early role, it helped George begin building a screen résumé before she moved into larger film and television productions.
She also became associated with The Seagull, a production that demonstrated her interest in classical and dramatic material. These early projects helped her gain experience before her first major feature-film opportunities.
Mortal Engines Was a Major Career Step
One of Leila George’s most recognizable early film roles came in Mortal Engines.
Released in 2018, the science-fiction adventure film was produced by Peter Jackson and directed by Christian Rivers. George played Katherine Valentine, a young character connected to the powerful Valentine family.
The film featured a large-scale futuristic world involving mobile cities, political power, and survival. George appeared alongside actors including Hera Hilmar, Robert Sheehan, Hugo Weaving, and Jihae.
Although Mortal Engines did not become the major commercial success its studio hoped for, it was still significant for George because it placed her in a large international production early in her career. Rotten Tomatoes lists the film among her notable credits.
The project also gave her experience working on a production involving substantial visual effects and an international cast.
The Kid and Working With Her Father
George next appeared in The Kid, a Western directed by her father, Vincent D’Onofrio.
The 2019 film featured Ethan Hawke, Dane DeHaan, Chris Pratt, and other well-known actors. George played Sara Cutler.
The movie gave George an unusual professional experience because she was working under her father’s direction while also sharing the screen with established actors.
The role helped demonstrate that she could work comfortably in a more traditional dramatic setting rather than being limited to large-scale fantasy productions.
Leila George in Animal Kingdom
Arguably the most important television role of Leila George’s career came with Animal Kingdom.
She joined the TNT crime drama as Janine, the younger version of Ellen Barkin’s character, Janine “Smurf” Cody. The role was particularly demanding because George had to portray a character at several different stages of her life.
In the series, flashbacks explore Smurf’s younger years and show how she developed into the powerful and ruthless matriarch seen in the main timeline.
George’s version of Janine appears during multiple seasons and became a significant part of the show’s backstory. She was credited in 39 episodes of the series.
The casting was announced ahead of the show’s fourth season, with George described as playing a younger Janine who was a resourceful and street-smart survivor.
Her work on Animal Kingdom was important because television gave her more room to develop a character over time. Instead of appearing in only one film, she returned repeatedly and helped audiences understand how Smurf’s personality and criminal instincts developed.

Leila George’s Later Movie Career
After establishing herself through Animal Kingdom, George continued appearing in films.
She played September McAvoy in Gonzo Girl, a 2023 film starring Willem Dafoe and Patricia Arquette. The movie offered George another opportunity to work within an ensemble cast and explore a more character-focused story.
She subsequently appeared in He Ain’t Heavy as Jade. The 2024 film added another dramatic credit to her growing filmography.
George has also continued taking television roles, showing that she is not focused exclusively on movies.
Leila George in Disclaimer
In 2024, George appeared in Alfonso Cuarón’s Apple TV+ psychological thriller series Disclaimer.
The series starred Cate Blanchett, Kevin Kline, Sacha Baron Cohen, and other major actors. George played Young Catherine, contributing to the show’s story through its layered timeline.
Disclaimer was another important project because it placed George in a prestigious television production with an internationally recognized director and a high-profile cast. IMDb lists her among the series’ cast for seven episodes.
The role further strengthened her television résumé after her work in Animal Kingdom.
The Beast in Me
George also appeared in the 2025 Netflix limited series The Beast in Me.
She played Madison Ingram Jarvis in the series, which stars Claire Danes and Matthew Rhys.
Although George’s role is not the central character, appearing in another high-profile streaming production shows the continued development of her television career. IMDb lists the series among her recent credits.
Leila George in Love Story
One of George’s most recent television roles is in Love Story, the 2026 series centered on John F. Kennedy Jr. and Carolyn Bessette.
George plays Kelly Klein, a character connected to the fashion world and Carolyn Bessette’s professional circle. The series features Paul Anthony Kelly as John F. Kennedy Jr. and Sarah Pidgeon as Carolyn Bessette, with Naomi Watts portraying Jacqueline Kennedy Onassis.
George’s casting was announced as part of the recurring cast, and IMDb credits her as Kelly Klein.
The series represents another change in genre for George, moving away from crime dramas and science-fiction films toward a historical romantic drama inspired by real people and events.
Leila George’s Upcoming Movie Runner
Another important project for George in 2026 is Runner.
The film stars Alan Ritchson, Owen Wilson, Rodrigo Santoro, and Leila George. Ritchson plays Hank Malone, while George plays Kate Baker. The story follows a former soldier who becomes the target of a cartel while attempting to deliver critical medical supplies.
Runner is scheduled for a wide theatrical release on September 11, 2026.
For George, the film represents another move into action-oriented mainstream cinema. It also puts her alongside actors with significant experience in action and comedy.
All the Sinners Bleed
George is also attached to Netflix’s All the Sinners Bleed, a limited crime series based on S. A. Cosby’s novel.
The series was ordered by Netflix in 2025, and George joined the cast in November of that year. Current film databases list her role as Marlow Stoner. Production began in Atlanta in late 2025 and continued into 2026.
The project gives George another opportunity to work within a crime-focused story, a genre that already connects with her successful Animal Kingdom experience.

Leila George and Sean Penn
Leila George’s personal life attracted considerable media attention because of her relationship with actor Sean Penn.
The pair began dating in 2016 and married on July 30, 2020. Their wedding took place during the COVID-19 pandemic and was described by Penn as a small “COVID wedding.”
However, the marriage did not last. George filed for divorce in October 2021. The divorce was finalized on April 22, 2022. Court documents cited irreconcilable differences, and neither party sought spousal support from the other.
George and Penn did not have children together.
Since then, George has largely focused attention on her acting career and professional projects.
Does Leila George Have Children?
Leila George does not have children with Sean Penn. The former couple’s marriage lasted from 2020 until their divorce was finalized in 2022.
George generally maintains a relatively private personal life, so information about her relationships outside her well-documented marriage is limited.
Leila George’s Acting Style and Career Development
One of the most interesting aspects of George’s career is the variety of characters she has played.
She has appeared in science fiction through Mortal Engines, Western drama through The Kid, crime drama through Animal Kingdom, psychological drama through Disclaimer, and historical television through Love Story.
Her role in Animal Kingdom particularly helped distinguish her from being known simply as the daughter of two famous actors. Playing a younger version of one of the show’s central characters required her to create a believable connection with Ellen Barkin’s portrayal while also making the younger Janine feel like her own person.
At the same time, her more recent projects suggest that she is continuing to experiment with different genres rather than repeating one successful formula.
What Is Leila George Best Known For?
For viewers who discovered George through television, Animal Kingdom is probably her most important role. Her portrayal of young Janine “Smurf” Cody gave her a substantial recurring part and allowed her to remain on the show across several seasons.
Movie audiences may know her from Mortal Engines and The Kid, while more recent streaming audiences may recognize her from Disclaimer and The Beast in Me.
Her 2026 work is also expanding her visibility through Love Story and Runner. As these projects reach wider audiences, George’s profile is likely to continue growing.
