Gao was reported to have been cast by Deadline on 2 November 2020 alongside Donal Logue and Chad Rook. Rook would confirm on his Instagram Gao was indeed playing the role of Ada Wong.[3] Although more material was filmed, the theatrical version would only include Gao's Ada in a mid-credits scene, and one other was made available online for viewing. Following her appearance in the film, Gao was asked to reprise the role by Capcom, who were satisfied with her performance and had interests in committing to Asian actor-character representation for the franchise. Capcom's commitment to "stoic" voice direction and the departure of previous Ada voice actress Jolene Anderson led to harassment and cyberbullying on social media shortly after the game was released.[4]
