Daybreakers poster
This poster makes it pretty clear: Daybreakers is more of a sci-fi picture than it is a vampire one. Lionsgate will drop this in the January graveyard, so take that for what you will. The premise certainly makes Daybreakers sound more promising than the release date.
From Lionsgate:
Ethan Hawke plays Edward Dalton, a researcher in the year 2019, in which an unknown plague has transformed the world’s population into vampires. As the human population nears extinction, vampires must capture and farm every remaining human, or find a blood substitute before time runs out. However, a covert group of vampires makes a remarkable discovery, one which has the power to save the human race.
