Christopher Vourlias Palestinian director Hana Elias’ “If These Stones Could Talk,” which follows a Palestinian man’s return to his homeland to restore his family’s ancestral garden, and Argentine filmmaker María Silvia Esteve’s “Mailin,” about a woman’s painful struggle to overcome her childhood trauma, took the top prizes at the Thessaloniki Documentary Festival’s industry award ceremony Wednesday night. During an emotionally charged conclusion to the festival’s Agora strand, in which several filmmakers voiced their strident support for Palestine and called for a ceasefire to the more than five-month-old Israel-Hamas war in Gaza, a tearful Elias took the stage alongside producer Asmahan Bkerat to receive the top prize in the Agora’s pitching forum, a €10,000 ($10,900) cash prize from the International Emerging Film Talents Assn. (IEFTA).
