List of Let the Right One In characters

One of the few friends he has is Tommy, who is a major character in the book, but is omitted from both films save one fleeting mention by Owen in Let Me In.

Oskar/Owen is constantly harassed in school by a group of bullies that enjoy torturing and humiliating him, and he fantasizes of one day standing up for himself and injuring or disposing of them.

The two eventually form a close bond when she notices he is playing with a Rubik's cube, and, because of her fondness for puzzles, Eli's/Abby's interest is piqued.

In the 2010 film, Owen's mother is a neglectful Christian alcoholic and her face is never shown, which might explain why he is drawn to Abby.

While the character of the same name in the 2008 film is assumed to have similar characteristics, any details surrounding his potential pedophilia or history with Eli are not revealed, only hinted upon in their dialogue and a few scenes.

Within the film plots, Håkan is used as a foreshadowing of what Oskar / Owen will eventually become, while the sequel short story "Let the Old Dreams Die" features a different outcome.

Lacke is a local middle-aged male resident of Blackeberg whose story and group of friends play a major role in both the novel and the 2008 film Let the Right One In, where he eventually becomes an antagonist to the main characters.

Lacke is completely omitted from the 2010 film Let Me In, and is replaced by an unnamed authority figure credited as "The Policeman".

Lacke first becomes involved in the main storyline when his friend Jocke disappears after Eli attacks him for blood, an event that is witnessed by Gösta, one of the townspeople.

When Jocke's dead body is found and it is revealed that Eli must have killed him, Lacke is determined to investigate the situation.

Virginia in the novel and original Swedish film is a middle-aged woman who is the on-again/off-again girlfriend of major secondary character Lacke.

He is the first major character that is seen on-screen in Let Me In, and serves alongside Owen's bullies as the main antagonist of the film.

He is the leader of a posse of bullies, who is seen doing acts such as beating Owen/Oskar with an antenna rod (a light tree branch in the novel), in the 2010 film, he is seen trying to pull off a girl's bathing suit in a public swimming pool, and even willing to kill Owen/Oskar.

As he begins to drown Oskar/Owen, Eli/Abby arrives and slaughters the bullies, Jimmy was the first to die in the American film as his head was ripped off and thrown in the water.
