This paper analyzes director Roberto Fiesco's narrative and ethnographic approach in the documentary "Quebranto" (2013), focusing on Coral Bonelli, a transgender woman, dancer, and sex worker from Mexico City. Fiesco blends audiovisual techniques and archival footage to biographically depict Bonelli, using oral testimony and innovative editing. Drawing on Diana Taylor’s and Sarah Pink’s theories, the study explores how these elements manage the biographical and emotional depth of Bonelli's story. It examines spatial elements in the film, which construct a narrative voice and contribute to Bonelli’s portrayal. Ultimately, the paper explores how Fiesco’s strategies convey Bonelli’s transcendence through archival footage, personal performance, and narrative innovation, pushing the boundaries of documentary cinema in representing queer subjectivity.
