I had to imagine myself into certain aspects of [Julian Assange] character for our version of events. That involved extrapolating based on clues in his biography, his public persona, photographs, and other accounts of him by people who encountered him during that extraordinary period from 2007 to 2010 that we charted in the film [The Fifth Estate ]. So, it involved a lot of research but, sadly, no contact with the man himself.
