TAULL, Spain — In an early prize at the Locarno film festival, Pablo Delgado Sanchez’s “The Tears” has topped the Swiss fest’s second Carte Blanche pix-in-post showcase.Featuring seven Mexican features, all courting completion finance, Carte Blanche carries a Swiss Franc 10,000 ($10,300) cash prize. “Tears” centers on Fernando and Gabriel, two brothers from a broken home who escape for a weekend in the woods, where Gabriel witnesses his elder brother’s self-destruction. Shot in 16mm off a 20-page bible, “Tears” relied on constant improvisation. According to Delgado Sanchez, it turns on a theme that he would like to explore in further movies: the family and its conflicts. “Tears” is Delgado Sanchez’s feature debut and graduate film at Mexican film school the Centro de Captacion Cinematografica (CCC), which doubled up as the film’s producer. The Locarno plaudit reps another step-up for the CCC, an emerging production force in Mexico. Two movies from CCC alums — Daniel Castro’s “Tau” and Jimena Montemayor’s “Land of Nod” — also screened at Carte Blanche. Deckert Distribution has meanwhile acquired sales rights to Europe, Asia and Africa on Tatiana Huezo’s docu “The Tiniest Place,” a CCC production which proved a standout at last year’s Guadalajara festival. The CCC has now completed production on Luciana Kaplan’s docu “Eufrosina’s Revolution” and Isabel Munoz Cota’s “Inertia,” and finished shooting David Pablo’s “La vispera del abismo.” “Inertia” and “Vispera” are both fiction features.
