Production finally started on Sally El Hosaini's latest film The Swimmers after a year-long delay, online magazine Variety reported.
The Netflix and Working Title film tells the true story of sisters Yusra and Sarah Mardini, who left Syria in 2015 and were at the Rio Olympics one year later.
The sisters' story made international headlines when, after fleeing the war, they left for Greece from Turkey in an overcrowded dinghy. But, when the engine failed 15 minutes into the trip, they had to swim for three and a half hours in a bid to stop the boat from capsizing.
Yusra went on to compete in swimming events in Rio in 2016 as part of the Refugee Olympics Team.
According to Variety, the film was only five days away from principle photography when the pandemic shut down productions worldwide last year.
Lebanese sisters Manal and Nathalie Issa will play the roles of the swimming sisters on screen. Manal won best actress at the Les Arcs European Film Festival for the 2015 film Parisienne.
James Krishna Floyd will also star in the film. He was the lead actor in El Hosaini's 2012 debut film My Brother The Devil, which picked up prizes at the Sundance, Berlin and London film festivals.
Announcing the start of production on his Facebook page, Mr Floyd said he was proud and humbled to be working on the project.
Based on a screenplay by El Hosaini and Bafta-winning screenwriter Jack Thorne, The Swimmers is set for global release next year. Shooting will start this week in the UK, then Turkey and Belgium, Variety said.
