Spain’s Fernando León de Aranoa is among many Directors’ Fortnight entrants working in English this year. His English-language debut, and first Cannes premiere, “A Perfect Day” stars Benicio del Toro (who also has Denis Villeneuve’s “Sicario” in competition), Tim Robbins, Olga Kurylenko and Melanie Thierry.

Adapted by de Aranoa from humanitarian doctor and author Paula Farias’ novel “Dejarse Llover,” the film follows a group of aid workers as they try to resolve a crisis in an armed conflict zone: Sophie (Thierry) is a newcomer who wants to help; Mambrú (del Toro) has seen it all and wants to go home; Katya (Kurylenko) once wanted Mambrú; Damir (Stukan) wants the war to end, and B (Robbins) doesn’t know what he wants.
