Tanya Moodie says her mother's history working in the NHS helped to inspire her performance as a nurse in Sam Mendes drama Empire of Light.The Motherland star plays Delia in the film — hard-working mum to Micheal Ward's character Stephen, who forms a surprising romance with cinema manager Hilary (Olivia Colman)."I felt an extra layer of responsibility because my mother is a nurse," Moodie told Yahoo UK. Empire of Light is in UK cinemas now.
