MADRID – London-based WestEnd Films will handle world sales rights outside Spain on Fernando Leon de Aranoa’s “A Perfect Day,” starring Benicio del Toro and Tim Robbins, Oscar winners for “Traffic” and “Mystic River,” and Olga Kurylenko (“To the Wonder,” “Quantum of Solace”), Melanie Thierry (“The Zero Theorem”) and Fedja Stukac (“In the Land of Blood and Honey”).

Just announced, “A Perfect Day” marks the sixth fiction feature of a distinguished Spanish director who has attracted high-profile thesps, and  won critical plaudits and often a large audience and international sales through films – “Barrio,” Javier Bardem-starrer “Mondays in the Sun,” “Princesses” – which feature a careful delineation of singular, robust individuals reacting, often with hangdog humor, to specific, often troubled social contexts.

“A Perfect Day” – on which pubcaster TVE has taken free-to-air Spanish TV rights – is no exception, turning on a group of aid workers in a conflict zone embark on a journey to find a rope in order to haul a dead body out of a well.

In neo-realist vein – though “A Perfect Day,” like realistic war films, mixes “humor, drama, emotion, routine, drama, and hope,” Leon de Aranoa said – that apparently simple, necessary task serves as a metaphor for a far larger view of the world and humanity, “one where the real enemy could be irrationality itself,” Leon commented.

“’A Perfect Day’ deals with a subject that’s not seen on the big screen very often. In that, it’s original. Its treatment is too: intelligence, warmth, humanity and that incredibly smart humor that’s the director’s trademark,” said Eve Schoukroun, at WestEnd Films.

She added: “We are very excited to work with such a talented director, quality actors and great producers.”

Rolling from March 17 in and around Granada, Andalusia, and one of the highest-profile Spanish films to shoot this year, “A Perfect Day” is produced by Reposado Producciones and Mediapro.
