A natural-born scene stealer, this versatile actress made a splash in her native Canada in TV-movies (The Diary of Evelyn Lau) and films (Double Happiness, which snagged her a Genie Award, the Canuck equivalent of an Oscar). In 1996 she became a familiar face on U.S. television on Arli$$ as a sports agent's sassy assistant. Oh continued to appear on the big screen, both in her homeland and Hollywood. In 2004 her career got a big boost when her then-husband, director-writer Alexander Payne, cast her as a sexpot in the Oscar-nominated film Sideways. The next year, she landed the star-making role of a sexy and sarcastic doctor on the hit drama Grey's Anatomy. Oh stresses the importance of acting on stage to her work as an actress and often finds time to return to the theater.
