Film & Television · Sydney, New South Wales
Sydney-born actress whose career has tracked from local Australian drama through the largest fantasy franchise on television to the lead of a tentpole DC feature in three years. Alcock played Meg Adams across three seasons of Foxtel's Upright opposite Tim Minchin, earning an AACTA nomination, before her international breakthrough as the young Princess Rhaenyra Targaryen in HBO's House of the Dragon — a performance that drew Critics' Choice and Saturn nominations.
In 2025 she appeared as Simone DeWitt in Netflix's Sirens and reprised her DC role in James Gunn's Superman; in 2026 she leads Supergirl as Kara Zor-El, the studio's next solo outing. She is, by industry consensus, one of the most in-demand Australian actresses of her generation.
