John Hopewell Chief International CorrespondentA leading light of Latin America’s new generation of female cineastes – think Michelle Garza Cervera, Valentina Mourel – “To Kill the Beast” director Agustina San Martín is teaming with Buenos Aires-based Vega Cine and Cordoba Argentina’s Gualicho Cine for a new feature, “Todo el Mundo.”Selected for San Sebastian’s 2022 Europe-Latin America Co-Production Forum in September, “Todo el Mundo” unspools in a world not so distant from “To Kill the Beast” (“Matar a la Bestia”) or the sensibilities of San Martín. A ’90s-set coming-of-age tale, it turns on the burgeoning relationship between Serena, 15, whose face is deformed after an accident, and Enzo, 17, a “dark” goth boy attracted by Serena’s scar. Serena begins to skip school, get home late and lie her mother. Her high-school friendships aren’t what they were before.
