The aim of this article is to analyse how 15 students at a public elementary school detach from immobile representations of identity through aesthetic self-expressive work with cinema. Drawing on Deleuze and Guattari's concept of assemblage, I interrogate students' experiences of discrimination and challenge their processes of developing a short film within cinema workshops at school. I find that when new components regarding cinema, such as material apparatuses (e.g. cameras, stages, sound recorders) and expressive devices (e.g. improvisation, dialogues, corporeal movements), are applied to both the school and subjectivities, there is a rupture of rigid systems of representation and the creation of novel assemblages.
