Production, announced by Variety, will be in charge of the Mexican company Caponetled by Martínez-Ulanosky, and Argentina Ajimolido. The film was selected to participate in the Europa-Latin America Co-production Forum of the San Sebastián International Film Festivalwhich will be held from September 19 to 27, with the forum planned from 22 to 24.


“When I read ‘It is not a river’ for the first time, their silences and their stark gaze on the wounded masculinity were persecuted”explained Martínez-Ulanosky, who will assume direction, script and production.
The forum as “ideal platform”
Almada’s novel, translated into more than 30 languageshas been consolidated as one of the most influential works of recent Latin American literature. His plot follows a teenager who accompanies two old friends of his deceased father at a weekend of fishing on the island where he died. There, the appearance of two young women blur the border between memory and reality, dragging the protagonists to an adjustment of accounts with the rivalry, the unpared desire and a past that refuses to disappear.
The Caponeto-Ajimolid Alliance is not new: they have already worked together in “I am afraid bullfighter” by Pedro Lemebel, presented at the Venice Festival, and “The Virgen de la Tosquera”inspired by Tales by Mariana Enriquez, who debuted in Sundance 2025 and won the Grand Prix in El Bafici.
For Livi Herrera, producer of Caponeto, the selection in San Sebastián represents “a great step”: “Acquiring rights was a real challenge, but each effort was worth it. This forum is the ideal platform to add collaborators who share our passion and help take the film to your next stage”
