Information found about 'Let the right one in'

Eli is a 12 year old girl, and she has been 12 years old for over 200 years because she is a vampire. Out of the three other films i am focusing on this is the only film with a child as the main female vampire. As Twilight uses teenagers.

Eli moves in next door to a young boy called Oscar, who is constantly bullied at school, but finally finds a friend in Eli. A similar trate between let the right one in and twilight is that both Eli and Edward say that they cannot be friends with Oscar or Bella because they know that vampires and humans cannot be friends, but in both films this is not the case. One other similarity is that both films begain as books, Let the right one in was a novel first.
