Daybreakers (2024)

In the end, Edward watches the sunrise over a ruined city. The cured stand beside him, blinking. They are no longer predators. But they are no longer pure, either. The cure rewrites DNA imperfectly: they age fast, tire easily, and dream in echo-location. Still, it’s a start.

But Bromley Marks learns of the cure. To the corporation, a cure means the end of blood dependency—and the collapse of their trillion-dollar empire. The CEO, Charles Bromley (Sam Neill), declares Edward a terrorist. More terrifyingly, Bromley has his own solution to the blood shortage: convert the last humans into livestock farms. Breed them. Bleed them. Never let them wake. Daybreakers

But there was a problem. The human supply was running out. In the end, Edward watches the sunrise over a ruined city

Edward Dalton (Ethan Hawke) is a chief hematologist for Bromley Marks, the corporation that now runs the global blood supply. Unlike his brother Frank (Michael Dafoe)—a grizzled vampire hunter turned human-sympathizer—Edward still clings to a scientist’s hope: a blood substitute. Each batch, however, fails. The test subjects (feral, starving vampires) vomit it back. Desperation turns to panic. Without blood, the vampire population degenerates into “subsiders”—bat-like, rabid creatures that lose all reason. But they are no longer pure, either
