French director Andre Techine said his new drama which debuted at the Berlin International Film Festival looks at the start of the AIDS epidemic in the 1980s because it deeply marked his personal life. "I lived through this period. And I have the feeling to have been spared a fate which many of my friends were not," he said after a press screening of "Les Temoins" (The Witnesses). "I wanted to talk about it because it changed my life, the way I live my relationships. I realised I was mortal." Emsie Ferreira reports.
