For the better part of 10 years, Chau took on smaller roles in various TV shows. After her appearance in "Inherent Vice," Chau got her big break in the 2017 film "Downsizing," in which she shared the screen with veteran actors Matt Damon, Christoph Waltz, and Laura Dern. She revealed the impact of the film to UpRoxx, saying, "Even though I had done 'Treme' and 'Inherent Vice,' I struggled to get auditions and I was still in the youth department of this agency that I was with because nobody in the adult department wanted to take me."
She continued, "It wasn't until 'Downsizing' came along that I had an opportunity to, I guess, showcase myself. And the people who did see it saw that there was an actor there who was making choices, and they weren't confusing me for the character."
