An Australian TV movie that chronicles the WikiLeaks founder’s years as a teenage computer hacker in Melbourne in the late 1980s screens Saturday at the Toronto International Film Festival. Newcomer Alex Williams plays Assange, with Rachel Griffiths as his activist mother Christine, Laura Wheelwright as his girlfriend, and Anthony LaPaglia as the cop who investigates the case. Written and directed by Robert Connolly and based on the 1997 novel Underground: Tales Of Hacking, Madness And Obsession On The Electronic Frontier by Suelette Dreyfus, the telepic was commissioned by Australia’s Network Ten, which will air it next month. NBCUniversal International is distributing worldwide. Assange is currently holed up inside the Ecuadorian Embassy in London to avoid being arrested and extradited to Sweden for questioning about alleged sexual misconduct or to the U.S. over Wikileaks’ release of confidential diplomatic information.
