We've got a long way to go until The Host hits theaters some time in 2013, but the first teaser trailer for the upcoming thriller is already online.
Based on a book by Stephenie Meyer - who penned something else called The Twilight Saga - The Host tells the story of an alien species that takes over the consciousness of human beings on Earth.
But these aliens didn't account for Saoirse Ronan's Melanie, who fights back against the invaders.
Check out the first trailer now, but be warned: the film hasn't even completed shooting yet. This just a preliminary tease. But it's a pretty darn intriguing one.
