Queer Theory challenges traditional notions of gender and sexuality, viewing them as social constructs rather than fixed categories. It examines concepts like heteronormativity, performativity, and queer temporality, while also exploring the creation of queer spaces and the intersectionality of marginalized identities. LGBTQ+ representation in cinema has evolved from early stereotypes and censorship to more nuanced portrayals. Pioneering filmmakers like Kenneth Anger and Pedro Almodóvar paved the way for diverse queer narratives, while contemporary cinema grapples with issues of stereotyping, intersectionality, and the impact of new media on queer storytelling.
