More than 700,000 people in Spain were affected by the preferred-shares scandal, in which customers were sold variable-income products without being properly informed of their terms. Many believed they were buying fixed-income investments and could withdraw their savings whenever they wished. When the financial crisis deepened, some discovered they could not get their money back.

That anger provides the starting point for Colisión, Daniel Sánchez Arévalo’s first thriller. The film imagines a bank heist as an act of revenge by people harmed by the scandal. It arrived on Netflix over the weekend and has reached the top of the platform’s most-watched films.

Set in 2013, the story combines the aftermath of the crisis with a structure that revisits the same events through different viewpoints and timelines. Sánchez Arévalo has described that approach as a kind of “multiverse,” while avoiding further details that could reveal the plot. The director said the idea came from producer Ramón Campos, who shared part of the script with him while they were finishing Rondallas.

Although Colisión marks a shift into action and suspense, Sánchez Arévalo says his focus remains on telling stories about characters. He was interested in the tensions within the group planning the robbery, including the relationships and personal conflicts that lead them to take part. He has described the film less as action for its own sake than as a story in motion.

The director also connects the film’s 2013 setting with conditions he says remain familiar in 2026: frustration, difficulty accessing housing and a sense that people at the top have failed to act. That social backdrop gives the heist story its foundation, while the film’s shifting perspectives drive its thriller structure.

Sánchez Arévalo has said he was initially concerned that making a thriller might feel out of place in his filmography. Instead, stepping away from his usual approach gave him a greater sense of freedom to take risks. He has also said he hopes to return to a smaller-scale story after Colisión.

Netflix has announced another project with the director, Chapapote, which will address the Prestige disaster as a dramatic comedy.
