The stars of Suicide Squad, Jai Courtney and Margot Robbins, visited the John St. lemonade stand of 5-year-old Na’ama Uzan set up to help her brother Nadav. He suffers from Angleman Syndrome, a rare congenital disorder caused by genetic malformations. “I heard about Na’ama’s story and what she’s doing for her brother Nadav,” Courtney told CTV Toronto. “There’s no act too small when you’re talking about making a difference.”
