In this clip from the 'Making Of' on the upcoming Blu-ray and DVD, the kid stars of 'Let Me In' (Chloe Grace Moretz and Kodi Smit-McPhee) confess that their on-camera performances are so creepy they even scare themselves. Also, Kodi admits that he HATES 'The Exorcist.''Let Me In' is a poignant coming-of-age story and a bone-chilling horror film as a bullied young boy befriends a young female vampire. In a pop-culture landscape littered with the bloodthirsty undead, 'Let Me In' stands out as a very different kind of vampire movie – a haunting meditation on the difficult and often painful transition into adolescence. Elias Koteas, Cara Buono and Richard Jenkins co-star, in an adaptation of John Ajvide Lindqvist's Swedish novel written and directed by Matt Reeves (Cloverfield).
