2006–2017: Early work and breakthrough with Downsizing Chau began acting in film and television in 2006. In the early 2010s, she had guest roles on the
CBS TV series
NCIS and
How I Met Your Mother. One of her first major roles was in the TV series
Treme (2010–2013), which was set in New Orleans. Her first feature film role was in the 2014 film
Inherent Vice. For two years after her role, she was not able to get an audition for another film role. She subsequently appeared in a supporting role in the 2017 film
Downsizing, She was nominated for several awards for best supporting actress (see
accolades). She appeared in guest roles in several TV series, including
BoJack Horseman and
Forever. She had a supporting role as a corporate secretary in the first season of the
Amazon Prime Video series
Homecoming.
The Ringers Alison Herman said another actor would have sought to accumulate more recurring roles on TV series. Herman said, "In the Peak TV Era, Chau opted for something much savvier: taking some choice guest parts in a few critically acclaimed TV shows ... Chau benefits from these shows' prestige; the shows benefit from her talents." Chau had her first leading roles in the films
Driveways and
American Woman, both released at film festivals in 2019. For
Driveways, Chau was familiar with director
Andrew Ahn's previous film
Spa Night, recognized his name when he contacted her with an offer for the role, and readily accepted the offer. Also in 2019, Chau appeared in the HBO limited series
Watchmen as the trillionaire Lady Trieu, whose performance
The Hollywood Reporters TV critic Tim Goodman said was one of the series' "exceptional, memorable performances". In May 2020, Chau had a larger role in
Homecomings second season, in which she moves from secretary to a person in charge in the series's featured corporation.
Entertainment Tonights Stacy Lambe said Chau "has become something of a scene stealer over the years". Lambe said, "What's notable about most of her projects is that they feature a diverse cast of actors of color who get to shine in unexpected ways," highlighting
Treme,
Watchmen, and
Homecoming. While Chau had filmed a small part as
Opal Koboi in the 2020 film
Artemis Fowl, her appearance was ultimately cut. Her character's voice was used, but Chau was not officially credited. Her deleted scene became available on
Disney+.

The Whale,
Showing Up,
The Menu, and
Asteroid City. Chau was initially reluctant to audition, preferring to stay home with her newborn and doubting she would get the role as it was originally played by a white actress. For
The Menu, Chau was a fan of the TV series
Succession and wanted to work with director
Mark Mylod, who had directed over a dozen episodes in the series. She also wanted to work with actor
Ralph Fiennes.

2022 Cannes Film Festival, and in September,
The Whale premiered at the
79th Venice International Film Festival, and
The Menu premiered at the
2022 Toronto International Film Festival. Both
The Whale and
The Menu had commercial releases in theaters later in the year. Chau said she gives directors "a wide range of line readings and reactions each time they call 'action'".
Variety wrote, "It's resulted in a string of performances of remarkable versatility, star turns." For her role in
The Whale, Chau was nominated for the
Academy Award for Best Supporting Actress. Chau appeared as a guest star in an episode of the TV series
Poker Face, which premiered in January 2023. Chau also appeared in the TV series
The Night Agent, which premiered on March 23, 2023. Chau was familiar with series creator

The Shield and
Terriers and accepted the opportunity to work with Ryan and to have a role in a political thriller that would be new genre territory for her. Chau had a single scene in
Asteroid City, which premiered at the
2023 Cannes Film Festival. She was part of another ensemble cast in
Yorgos Lanthimos's
absurdist anthology film

Doug Liman. == Personal life ==
