Nick Vivarelli International Correspondent Oscar-nominated Tunisian filmmaker Kaouther Ben Hania (“Beauty and the Dogs,” “The Man Who Sold His Skin”) is back in Cannes with “Four Daughters” a powerful drama that mixes documentary and fiction to delve into the story of Tunisia’s Olfa Hamrouni who rose to international prominence in April 2016 when she publicized the radicalization of her two teenage daughters who had left Tunisia to fight with ISIS. The film, which is the only Arab entry in competition, stars Egyptian-Tunisian star Hend Sabri in the lead role of an actor who must play Hamrouni and gets coaching from the real Olfa on how to prepare for the role. Ben Hania spoke to Variety about the bold choice she made.
