Daybreakers (2009)

A 2009 sci-fi horror set in a dystopian 2019, where most of the population has been turned into vampires who are going hungry thanks to a limited supply of humans and their tasty blood. Big company Bromsley Marks Corp is trying to breed and harvest humans to keep the population alive but is finding it hard because the Vampire Army charged with hunting down the remaining humans tends to just eat the ones they find, which is, ya know, counterproductive. The conglomerate, therefore, is also trying to develop a synthetic blood substitute, but the chief hematologist Edward Dalton (Ethan Hawke) thinks the better plan is to cure vampirism altogether. He joins up with a secret band vampires and humans led by Willam Dafoe’s Lionel ‘Elvis’ Cormac, who may have the antidote Edward is looking for. But it’s Harriet Minto-Day who definitely has what we’re looking for - perky nips trying to break through a tight tank top!
