Jack Thorne has said he wanted to be involved in a film about a Syrian refugee who competed at the Olympics because there needs to be a change in attitudes. Netflix film The Swimmers is based on the inspirational true story of the Mardini sisters, who fled their war-torn home of Damascus in 2015 by boat and helped save the lives of their fellow refugees. The film will show how just a year after their treacherous journey, younger sister Yusra competed in swimming events at the 2016 Rio Olympics as part of the Refugee Olympic team.
