Imagine two strangers, bound by terror, forced to trust each other after a harrowing roadside kidnapping. This gripping premise is at the heart of I’ll Keep My Mouth Shut (No diré nada), a Colombian horror thriller that’s already making waves in the film industry. But here’s where it gets even more intriguing: Argentina’s Del Toro Films, known for their spine-chilling genre masterpieces, has just joined as a co-producer. Could this be the collaboration that takes this film from promising to unforgettable?
In a deal sealed at Ventana Sur—the bustling Latin American film market (https://variety.com/t/ventana-sur/)—Del Toro Films (https://variety.com/t/del-toro-films/) officially boarded the project, marking a significant step for director Óscar Adán’s feature debut. Adán, who co-wrote the script with María Adelaida Palacio Duque, brings a fresh voice to the genre. The film, presented at the VS Fantastic! Lab (https://variety.com/t/fantastic-lab/) by Colombia’s Cinematografiando, follows two women who form an unlikely alliance in the wake of a terrifying abduction.
Leading the charge are Colombian stars Paula Castaño (Dear Gentlemen) and Ángela Rodríguez (The Black Snake), supported by a powerhouse cast including Juan Pablo Barragán (The Squad), Nelson Camayo (One Hundred Years of Solitude), and Gerardo Calero (1989). Their talent alone promises a gripping performance, but it’s the film’s exploration of fear, survival, and human connection that’s truly captivating.
Produced by Cinematografiando’s Diana Contento, Andrés Tous, and Mario Cubillos Peña—a team celebrated for their cultural events, documentaries, and short films—the project gains an extra layer of depth with Del Toro Films’ involvement. Led by Arelis Ruiz and Néstor Sánchez Sotelo, Del Toro brings a wealth of experience in horror, with hits like On the 3rd Day, Auxilio, and The Funeral Home under their belt. These films have not only graced genre festivals but have also found distribution across multiple territories, setting a high bar for I’ll Keep My Mouth Shut.
And this is the part most people miss: the film is already on a winning streak. After participating in Mexico’s Feratum Pitch Hub and Colombia’s Fantasolab, it snagged the Special Jury Prize for Best Project and earned mentorship from VDF Connection. With financing nearly secured, principal photography is slated for the second quarter of 2026.
The co-production agreement was signed by Contento and Tous from Cinematografiando and Ruiz and Sánchez Sotelo from Del Toro Films. Meanwhile, talks are ongoing with Lucas Pelegrino of Brazil’s LPB Content, hinting at an even broader international collaboration.
But here’s the controversial question: Can a horror thriller rooted in such a dark, visceral premise truly resonate with a global audience? Or will its intensity alienate viewers? The Fantastic! Lab, which featured standout projects like Sitges Festival winner La Huida, Peek a Boo (a Pulsar Santa Fe 2025 Fast Track winner), and Belgium’s Vautours (awarded at the Brussels International Fantastic Film Festival), suggests there’s an appetite for bold storytelling.
Organized by Argentina’s INCAA, Uruguay’s ACAU, and the Marché du Film – Festival de Cannes, Ventana Sur (held in Buenos Aires from December 1-5) proved once again to be a hotbed for innovative cinema. As I’ll Keep My Mouth Shut moves forward, it’s not just a film—it’s a conversation starter.
What do you think? Will this thriller live up to the hype, or is it too niche for mainstream success? Let us know in the comments—we’re eager to hear your take!
