In 2017, at the age of 80, Redgrave made her directorial debut with the feature documentary "Sea Sorrow", which covers the plight of child migrants in the Calais refugee camps and the broader European migrant crisis. It premiered at the 2017 Cannes Film Festival. Critics praised the documentary's message but criticised the structure for a "scattershot lack of focus" and the "ungainliness of its production values."
