Part of Lost featuring Matthew Fox, Josh Holloway, Jorge Garcia, Terry O'Quinn, and Naveen Andrews.
Rise to Fame
She had almost no credits when she auditioned for Kate Austen in 2003. Around 75 women tried for the part. Lost premiered in September 2004 and became one of the defining TV events of the decade, taking her from commercials and uncredited background work to a Golden Globe nomination in under a year. The kind of breakthrough that looks obvious in retrospect but genuinely wasn't.
In the Spotlight
After Lost ended in 2010, she came back for The Hobbit films as an elf invented specifically for the movies. Then the MCU, playing Hope van Dyne/Wasp across four films from 2015 through 2023, including Avengers: Endgame. The Wasp was the first female superhero to headline an MCU title. In 2024 she announced stepping away from acting. Then in May 2025, she fell face-first into a boulder at a Hawaii beach and confirmed in January 2026 that the accident caused brain damage affecting her entire brain. She's been recovering in Australia since.
Side Notes
She has a degree in International Relations from the University of British Columbia and ran a world development and human rights committee while there. She made multiple trips to Rwanda for charity work. In 2022 she marched against vaccine mandates in Washington D.C., which cost her some public goodwill. The profile that emerges isn't really a Hollywood actress. It's someone who kept treating acting like a day job.
