Marta Balaga Lille-born filmmaker Benoît Chieux has been coming to Annecy for 30 years. This year, to his own amazement, he is opening the festival with “Sirocco and the Kingdom of Air Streams.” “It’s an incredible surprise and a huge honor. Today’s competition [in animation] is very tough and there are so many high-quality feature films out there,” he says, calling the event “an exceptionally rich place to meet and discover new things.” In “Sirocco,” two sisters, Juliette and Carmen, discover a secret passage to the world of their favorite book, the Kingdom of Air Streams. Transformed into cats and separated from each other, they will have to find their way back and – with the help of talented singer Selma – confront the mysterious Sirocco, the master of winds and storms.
