Early life

Claudia Kim was born Kim Soo-hyun on 25 January 1985 in Seoul, South Korea. She spent part of her childhood in the United States, in New Jersey, which gave her fluent English and an international outlook. She first worked as a model and won a Korea-China modelling contest before turning to acting.

Career and breakthrough

Her global breakthrough came step by step: a warrior role as Khutulun in Netflix's Marco Polo (2014) led to Avengers: Age of Ultron (2015), one of the biggest films in the world. She then joined The Dark Tower and played Nagini in Fantastic Beasts: The Crimes of Grindelwald (2018), becoming one of the few Korean actresses with major roles in several Hollywood franchises.

She showed a fun new side in The Atypical Family (2024) as Bok Dong-hee, and in Sacred Jewel (2026) she plays Wang-hee in a sweeping historical story.
