Considering its roots in Chinese culture, it's only natural that Over The Moon's cast and crew was filled with people of Asian descent. This wasn't an accident. According to Peilin Chou, one of the producers of Over the Moon, this cast make-up was essential to her, as a Taiwanese immigrant, and to other members of the film's creative team.
In an interview with NBC, Chou explained that many cultural norms and familial dynamics seen in the movie, such as Fei Fei's grandmother asking if she has eaten enough, are crucially important, but "not really something you can research." They're intimately understood and recognized, however, by many Asian people. As Chou noted, "It's not the same if you're a white person from Cleveland, Ohio, and you are supposed to play a Chinese moon goddess. I don't know how you connect with that in anywhere near the same way."
Chou also spoke about the film's voice talent and how they related to their characters, saying," Philippa Soo, who is half Chinese and plays Chang'e, she talks a lot about, for example, when she embodies the role, how much it was influenced by growing up knowing the myth ... Culturally, growing up in that kind of family just really informed what she brought to the role."
