Vampire action flick Daybreakers is the first mainstream film to be directed by Michael and Peter Spierig.

The Australian siblings – best known so far for their 2003 zombie/alien crossover Undead – have snared some big names to bring us the story of a world where most of the population have become vampires and human blood is a precious, dwindling resource.

Starring Willem Dafoe, Ethan Hawke and Sam Neill, the film is due out at the start of 2010. While it’s built on the not-so-subtle allegory of earth’s greedy over-consumption of natural resources, it’s supposed to be as much comedy as action, and we’re asked not to take it too seriously.
