Oona Castilla Chaplin

Oona Castilla Chaplin (; born 4 June 1986) is an actress. Her roles include Talisa Maegyr in the HBO TV series Game of Thrones, Kitty Trevelyan in the BBC drama The Crimson Field, Zilpha Geary in the series Taboo, and Varang in the Avatar film series.

Early life Chaplin was born in Madrid to English-American actress Geraldine Chaplin and Chilean cinematographer Patricio Castilla. She has a half-brother named Shane from her mother's previous relationship with film director Carlos Saura. A member of the Chaplin family, she is a granddaughter of English filmmaker and actor Charlie Chaplin, and great-granddaughter of American playwright Eugene O'Neill. She was named after her maternal grandmother Oona O'Neill, Charlie Chaplin's fourth and final wife.

Growing up, Chaplin spent time in Spain, the United Kingdom, Switzerland and Cuba. She travelled often because of her mother's film career. She started dancing ballet, salsa and flamenco at an early age.

When Chaplin was 15, she began studying at Gordonstoun School in Scotland on a drama scholarship. She appeared in several school plays; toured the United Kingdom in an adaptation of Romeo and Juliet; and impersonated her grandfather in the role of Bottom in an adaptation of A Midsummer Night's Dream at the Edinburgh Festival Fringe. After leaving Gordonstoun, she was accepted into the Royal Academy of Dramatic Art (RADA) in London, where she graduated in 2007. In 2024, she presented the BBC radio documentary Hollywood Exiles, which covered her grandfather's blacklisting by the House Un-American Activities Committee.

In 2025, Chaplin co-starred in Avatar: Fire and Ash, directed by James Cameron, as the villainous Varang. On casting the relatively unknown Chaplin, Cameron explained: "There was something [Chaplin] just locked into. There's a sexuality; there's a dominating psychology, and there's a lot of fury. There are a lot of layers to what she's doing there and the forces that are driving her. Oona was able to move fluidly back and forth between those in a way that I wasn't seeing with the others."
