About Milly Alcock

Edited by the community

Milly Alcock is an Australian actress who has built an international career in television and film. She started acting professionally around age 14, and since then she has appeared in a range of projects that show her versatility. Her breakthrough role came as young Rhaenyra Targaryen in the HBO fantasy series House of the Dragon (2022–2024), a performance that earned her a Critics' Choice Television Award nomination for Best Supporting Actress in a Drama Series.

Before that, she gained attention in her home country with the Foxtel comedy-drama Upright (2019–2022), for which she received an AACTA Award nomination. Born in Sydney, New South Wales, Australia, she grew up there and lived with her family while taking on side jobs to support her acting ambitions. Her career soon took her to London, where she first stayed in Primrose Hill before moving to an East London flat.

In January 2024, it was announced that she had been cast as Kara Zor-El / Supergirl in the DC Universe film Supergirl: Woman of Tomorrow (2026). She will also appear in the Netflix dark comedy limited series Sirens, alongside Julianne Moore and Meghann Fahy. Milly stands 5'2" with a slim build, brown hair, and blue eyes, and she maintains an active presence as an influencer, with 2.0m followers on Instagram. She is still early in her career, and her upcoming roles promise to expand her reach.

She is 26 years old.
