Director Nabil Ayouch pays tribute to artistry of Morocco's Sheikha singers

Moroccan director Nabil Ayouch tells us about the Aïta tradition of sung poetry at the centre of "Everybody Loves Touda" as his latest film gets a release in France. He tells us why actress Nisrin Erradi was the perfect choice to play the central character, sharing some of her personality traits, and about Nisrin's commitment to the serious training required to take on the role. Ayouch also tells us about challenging gender stereotypes and social norms in Morocco through his cinema and about music's expressive power when it comes to saying the unsayable.
