Rejecting critiques of the final line of Greta Gerwig's Barbie as a bioessentialist classification of gender, we engage with the Deleuzian concept of becoming to argue that this final line is not only gender inclusive but gender expansive, particularly within the current political moment. Challenging settled, hegemonic gender identities through the unsettled and dynamic possibilities of becoming, we explore how this dialogue can be interpreted as messaging to promote bodily autonomy for all by focusing on the essential role of reproductive and sexual health as necessary for liberation. Despite Barbie exemplifying white feminism and commodifying liberatory messages into a product, the audience and their connections with the film's messages generate the possibilities of liberating white feminism from its self-imposed limitations through becoming and deterritorialisation.
