Documentary film is a popular resource amongst peacebuilding organisations and practitioners. Despite this popularity, research on documentary film is still emerging in peace and conflict studies. This article explores documentary film’s role in the study and practice of peacebuilding by examining the documentary Demons in Paradise and its engagement with issues of peace and conflict in post-war Sri Lanka. This article makes conceptual, methodological, and empirical contributions. Drawing from empirical research, I identify and discuss documentary film’s engagement along three analytical angles: documentary film as a text, within social processes, and within research processes. Under each angle, I explore how empirical observations and understanding of peace emerge through the visual, using diverse methods and data, including interviews, participant observation, visual elicitation in post-screening focus groups, and film analysis. I conclude that documentary film can contribute to the study and practice of peacebuilding by offering multiple analytical angles that elucidate plural, disparate understandings of peace in post-war societies.
