This chapter examines the writing and development of a cinematic virtual reality (CVR) documentary titled Impact: Beyond the Night Sky (2020), that was written, directed and co-produced by the author. The chapter adopts an exegetical style as it reports on this creative research project, providing an opportunity to explore the concepts presented in the previous chapters through practice, and demonstrating a creative-critical approach in action. The author explores how the physical expression of a CVR documentary concept captures the conceptual and technical aspects that are imperative for successful realisation of the work. Through an analysis of the script and other planning documentation for Impact: Beyond the Night Sky, this case study evidences the challenges associated with writing for a spatialised medium.
