Social-issue documentaries are art for civic imagination and social critique. Today, audiences experience documentaries that interrogate topics like sexual assault in the military (The Invisible War), the opioid crisis (Heroin(e)), racial injustice (13th), government surveillance (Citizenfour), animal captivity (Blackfish), and more. Along a continuum of social change, these intimate nonfiction films have changed national conversations, set media agendas, mobilized communities and policymakers, and provided new portals into social problems and lived experiences—accessed by expanding audiences in a transforming dual marketplace that includes mainstream entertainment outlets and grassroots venues. Against the activism backdrop of the participatory networked culture, the contemporary function of social-issue documentaries in civic practice is embodied also in parallel community engagement—the active role of civil society, communities, and individuals—that has dynamically evolved over recent decades. Story Movements: How Documentaries Empower People and Inspire Social Change explores the functions and public influence of social-issue documentary storytelling in the networked era. At the book’s core is an argument about documentary’s vital role in storytelling culture and civic practice with an impulse toward justice and equity. Intimate documentaries illuminate complex realities and stories that disrupt dominant cultural narratives and contribute new ways for publics to contemplate and engage with social challenges. Written by a documentary producer, scholar, and director of the Center for Media & Social Impact, the book features original interviews with award-winning filmmakers and field leaders to reveal the motivations and influence of some of most lauded, eye-opening stories of the evolving documentary age.
