In this article the author discusses Foucault's heterotopia analytic and applies it to a film analysis of Quinceañera. Engaging in feminist and critical media scholarship, the author outlines U.S. discourses on girlhood and their collusion with patriarchal and heteronormative discourses on Latino cultural nationalism in the regulation, control, and representation of Latina youth living in the United States. Heterotopia is used as a critical tool to explore two scenes in Quinceañera that push conceptual boundaries of gender and sexuality. The author suggests that heterotopia is a useful pedagogical tool and that Quinceañera is a useful pedagogical source in conceptualizing girls' agency and resistance. Ultimately, this analysis traces some of the ways that the film's Latina youth protagonist regulates and transgresses gender and sexuality norms that are upheld by U.S. discourses on girlhood and patriarchal and heteronormative discourses on Latino cultural nationalism.
