This presentation is an account of my approach to visualising and structuring some elements of the research underpinning my recent television documentary film The Trouble with Merle (2002) about Merle Oberon, the Hollywood star of the 1930s and 40s. The film unpicks the competing stories and claims made by different groups for Oberon’s ethnicity and nationality: that she was either born in India of Anglo-Indian ancestry or that she was Tasmanian-born of Chinese ancestry. In the process of uncovering these stories, the film reflects on celebrity and memory and the way in which racism can shape a life.
