This chapter traces a circular and transnational research journey across migrant and Indigenous screen media, interweaving activism, scholarship, and storytelling. It reflects on my trajectory from anti-racist activism with migrants and refugees in Bologna, to collaborations with Indigenous scholars and artists in so-called Australia, and finally back to Italy to engage in participatory action research with migrant youth in Prato. Through this path, I develop an activist research methodology rooted in decolonial theory, Indigenous sovereignty, and relational accountability. Combining autoethnographic reflection with close analysis of Ningla A-Na (1972) and Far Away is Home (2012), the chapter explores how migrant and Indigenous filmmakers have created transcultural collaborations that challenge settler-colonial narratives and dominant representations of both migration and Indigeneity. I argue for an expanded definition of migrant cinema—one that includes collaborative productions shaped by ethics of participation, custodianship, and mutual recognition. The chapter bridges screen studies and migration studies by showing how participatory storytelling and digital media practices can foster new forms of belonging and social engagement. Drawing on my recent work with youth in Prato, I reflect on how digital storytelling and arts-based participatory methods can reveal the complexities of urban superdiversity and open up spaces for intercultural dialogue. Ultimately, this chapter proposes a transdisciplinary model of scholar-activism that invites researchers to decolonise migrant cinema by centring Indigenous knowledges, engaging in collaborative practice, and reimagining media as a space of solidarity between migrant and Indigenous communities across diverse contexts.
