The 2023 film is notably less focused on individual heroism and more attentive to the collective experience — the group as a social organism, the ongoing negotiations about food and leadership and hope, the specific relationships between people who had to depend on each other completely. It uses a narrator who is one of the dead — a passenger who died in the crash and whose body became part of the survival — as a device for maintaining the perspective of those who died alongside those who lived.
The difference in approach between the two films reflects the different book sources on which they draw. Read’s *Alive* was written in the immediate aftermath of the survival, drawing on interviews conducted in 1973 and 1974. Vierci’s *Society of the Snow* was written thirty-five years later, drawing on the survivors’ accumulated understanding of what they had been through — an understanding shaped by decades of reflection, public speaking, return visits to the crash site, and the ongoing conversations among survivors that have continued since 1972.
Both films take creative liberties with the historical record that viewers should be aware of. Neither is a documentary. Scenes are condensed, timelines adjusted, and specific moments invented or combined for dramatic effect. The films are valuable as emotional and interpretive responses to a historical event, not as historical records in themselves.
The survivors’ own accounts — Parrado’s *Miracle in the Andes*, Canessa’s *I Had to Survive*, Pedro Algorta’s *Into the Mountains*, Eduardo Strauch’s *Out of the Silence*, and others — are the primary first-person records of the experience. They differ in some particulars, as accounts based on memory always do, and are consistent in their major outlines.
