The new red band trailer for Let Me In has been added to its official Facebook page. The vampire flick opens wide on October 1st, 2010. Check out the official trailer and bloody new image below.

Chloe Moretz (Hit Girl from Kick-Ass) stars as Abby, a mysterious 12-year old girl, who moves next door to Owen (Kodi Smit-McPhee, The Road). Owen is a social outcast who is viciously bullied at school and in his loneliness, forms a profound bond with his new neighbor. Owen can’t help noticing that Abby is like no one he has ever met before. As a string of grisly murders occupy the town, Owen has to confront the reality that this seemingly innocent girl is really a savage vampire.

Let Me In, a haunting and provocative thriller written and directed by filmmaker Matt Reeves (Cloverfield) and produced by legendary British horror brand Hammer Films, is based on the best-selling Swedish novel Lat den Ratte Komma (Let The Right One In) by John Ajvide Lindqvist, and the highly-acclaimed film of the same name.
