The document discusses the 'Challenge for Change' project initiated by the National Film Board of Canada in 1967, aimed at using documentary filmmaking as a tool for social change and poverty alleviation in underrepresented communities. Over 140 films were produced, allowing community members to participate in the filmmaking process and share their stories, thereby emphasizing community dialogue and empowerment. This approach marked a shift in documentary practices and underscored the potential for films to facilitate social transformation.
