When she's acting, Ella draws from strong, assertive female actresses for inspiration, including Natalie Portman and Jodie Foster. "When preparing for the role of Cassandra Cain, I actually used them as inspiration, especially Natalie in The Professional and Jodi in Taxi Driver," she explained to A Book of Us. Her greatest idol, however, is fellow Asian-American actress Sandra Oh. "I really want to represent the Asian community," she added. "That alone inspires me to act, because representation and diversity in the industry is super important to me."
