Josh Hartnett stars in this amazing, astonishing-looking, full-on horror thriller.

He’s the sheriff of Barrow, Alaska, the most northern town in the US where, for or 30 days in winter, there’s no daylight.

Ideal conditions then, for Danny Huston’s gang of bloodthirsty vampires to run amok.

But the intrepid Hartnett joins his estranged wife (Melissa George) to ensure they don’t have things all their own way, while creepy stranger Ben Foster is also hanging around.

Based on a graphic novel, this chiller is consistently startling and imaginative – and certainly doesn’t skimp on the gore, shocks and scares.
