Manori Ravindran International EditorThe Cannes Film Festival invited eight male directors for an hours-long symposium on the future of cinema on Tuesday — a session that raised uneasy questions for those working with streaming services, and paid no attention to the lack of female filmmakers on the panel.Moderated by Cannes festival director Thierry Fremaux and Canal+ correspondent and festival associate Didier Allouch, guests included Guillermo del Toro, Claude Lelouch, Costa Gavras, Gaspard Noé, Paolo Sorrentino, Nadav Lapid, Mathieu Kassovitz and Robin Campillo. The directors were interviewed individually, with Del Toro present on stage throughout.The session — which ran for two and a half hours, with speakers remaining a mystery until the event was underway — is one of two forums about cinema organized by the festival.
