- "We came to Australia only the day before filming. We did the last costume fitting -- which was only the second costume fitting -- so it was very nerve-wracking for them just in case things didn't fit. But it all went fine. I liked the whole look of the thing. It made me feel really proud to be wearing it."
- ―Keisha Castle-Hughes
Castle-Hughes received her Academy Award nomination for Best Actress in 2004 for her role in the film Whale Rider. While she did not win the award, she was at the time the youngest person nominated for the category, as well as the second Polynesian to be nominated for an Oscar. However, she won the Broadcast Film Critics Association Award for Best Young Actor/Actress for the role.
In 2006, Castle-Hughes played with Oscar Isaac in The Nativity Story, in which they portrayed the roles of Mary and Joseph. In 2009, Castle-Hughes appeared with Rena Owen (Taun We in Episode II and Nee Alavar in Episode III) in the TV movie Piece of My Heart. She played the young version of Owen's character. In 2011, Castle-Hughes also shared the screen with Rohan Nichol (Captain Raymus Antilles in Episode III) in the film Red Dog, and with Rachael Leigh Cook (voice of Jaesa Willsaam in the Star Wars: The Old Republic video game) in the film Vampire the same year.
From 2015 to 2017, she appeared in Game of Thrones alongside Jessica Henwick. In 2016, she worked on Roadies, a television series produced by J.J. Abrams, including on an episode directed by Jon Kasdan.
