Ellen Wong

Wong was born in Scarborough, Ontario, to Chinese Cambodian parents who fled Cambodia during the Cambodian genocide. She began acting in community theatre while attending L'Amoreaux Collegiate Institute and worked in a variety of television production jobs from the age of 14. She later studied radio and television arts at Ryerson University.

Wong continued acting while at university, and in 2005, she landed a role in the television series This Is Wonderland followed by Runaway in 2006. She also studies taekwondo but had to stop sparring competitively due to her acting schedule. Wong's martial arts background helped her land the role of Knives Chau in Scott Pilgrim vs. the World in October 2009. She auditioned for the part three times. On her second audition director Edgar Wright was surprised to find out that she studied taekwondo and was intrigued by this "sweetfaced young lady being a secret badass".

Wong expressed that the role of Knives Chau caught her eye because "it's not every day that as an Asian female, you get to be able to read a role that's empowering, that has a great arc, and that's so integral to the story as a whole". She also appeared in the television show Unnatural History. In 2011, she had a recurring role as Nurse Suzy Chao in the Global/ABC series Combat Hospital. In January 2012, she was nominated for an ACTRA Award for Outstanding Performance by a Female for her work portraying an illegal immigrant smuggled across the ocean in a shipping container in the short film Silent Cargo.

In February 2012, Wong was cast in the Sex and the City prequel series, The Carrie Diaries, playing Jill "Mouse" Chen, Carrie's best friend from high school who is described as "pragmatic, bright, and super loyal". In April 2012, it was reported that she had joined the cast of Silent Night, a loose remake of the 1984 horror film Silent Night, Deadly Night.

In June 2016, Wong was cast in the second season of the Syfy series, Dark Matter, and in October, she was cast in the Netflix comedy series GLOW, which was inspired by the 1980s female professional wrestling league of the same name. In the series, Wong plays Jenny, an immigrant from Cambodia who is obsessed with pop culture. Wong was initially dismayed to find out the character's wrestling persona was named "Fortune Cookie" but stated, "What is really awesome about GLOW is that we play these two characters. In the ring, you are these stereotypes. But then you see who these characters are in real life outside of the ring and how they feel... Jenny is trying to be this all-American girl in the '80s, and she's basically trying to fight all these stereotypes and at the same time here she is playing this stereotype." The creators of the series wrote the character's background as Cambodian after several meetings with Wong.

In 2017, Wong appeared in the thriller film The Circle, starring Emma Watson and Tom Hanks, and in Katy Perry's music video for "Swish Swish" as her character from GLOW.
