Holly Jones Coinciding with its world premiere at the Venice Film Festival, Warsaw-based New Europe Film Sales has provided Variety with an exclusive peek at the trailer for Chilean writer-director Fernando Guzzoni’s (“Jesus”) thriller, “Blanquita.” Based on the young witness at the center of the Spinak case, a scandal involving Chilean pedophilia and prostitution networks that rocked the country, the film grapples with morality and the struggle towards justice for those without means. In the film, Blanca (Laura López) leads investigators, and the public, on a baffling journey as she plants herself at the center of a trial against powerful politicians.
