Let the Right One In: Eli Castration & Gender Ambiguity

Few vampire films still spark the kind of quiet, obsessive debate that Let the Right One In does. Part coming-of-age story, part horror, it refuses to explain its most unsettling detail: whether Eli is a boy, a girl, or something else entirely, making it a touchstone for discussions about identity and monstrosity.

Year released: 2008 · Original language: Swedish · Director: Tomas Alfredson · Based on: 2004 novel by John Ajvide Lindqvist · Rotten Tomatoes score: 98% (Certified Fresh) · IMDb rating: 7.8/10

Six key facts shape the conversation around this film, covering its production, reception, and the central gender question.

What is Let the Right One In about?

Plot summary

• A bullied 12‑year‑old boy named Oskar meets a strange, pale child named Eli who moves into his Stockholm suburb apartment building.
• Eli is a vampire who needs human blood to survive, and Oskar’s growing friendship becomes a dangerous bond.
• The story intertwines Oskar’s revenge fantasies with a series of local murders linked to Eli’s caretaker, Håkan.

Set in the early 1980s in Blackeberg, a Stockholm suburb, the film uses snowy, muted visuals to create a claustrophobic winter atmosphere. The source novel by John Ajvide Lindqvist (Wikipedia, encyclopedia entry) expands the world with additional subplots involving a local drunk, a group of bullies, and a police investigation — much of which was cut for the film.

Setting and characters

• Oskar: a lonely, vulnerable boy who fantasises about standing up to his tormentors.
• Eli: an ageless vampire child who appears to be about 12 but has lived for centuries.
• Håkan: an older man who kills to provide Eli with blood (in the novel, he is a paedophile; the film hints at this).

The film deliberately avoids explaining Håkan’s past or Eli’s origin, leaving the viewer to piece together clues. Director Tomas Alfredson has said he wanted the audience to “feel the cold” and the emotional isolation of both characters (New York Times, leading newspaper).

Is Let the Right One In a good movie?

Critical reception

The film holds a 98% Certified Fresh score on Rotten Tomatoes, based on 184 reviews (Rotten Tomatoes, review aggregator). Critics consistently praise its reinvention of the vampire genre — it swaps gothic trappings for a muted, realistic setting and focuses on emotional restraint rather than bloodlust. Roger Ebert called it “a deeply moving, extraordinarily effective horror film” (RogerEbert.com, Pulitzer Prize-winning critic). Like some of the best speculative fiction, such as Black Mirror Beyond the Sea Ending Explained, it uses genre elements to explore deeper human questions.

Audience ratings

On IMDb, user ratings place it at 7.8/10 (IMDb, film database). On Letterboxd, it holds a 4.3 out of 5, with many members naming it one of the best vampire films of the 21st century. The film also won the Best Narrative Feature at the 2008 Tribeca Film Festival.

Critical reception across platforms:

The pattern: critics and audiences agree that Let the Right One In transcends genre labels. It is both a horror film and a tender, sometimes brutal, coming-of-age story. The catch: its slow pace and subtitled dialogue can be a barrier for viewers expecting action-driven vampire fare.

Was Eli a boy? Understanding Eli’s gender and “I’m not a girl” line

Eli’s ambiguous gender in the novel

John Ajvide Lindqvist’s 2004 novel is explicit: Eli was born a boy named Elias and was castrated by a vampire master before the events of the story (Wikipedia, encyclopedia entry). The novel includes a scene where Håkan sees Eli’s genital scar. This backstory was partially cut from the film, creating the ambiguity that has fueled interpretation.

Eli’s ambiguous gender in the film

Director Tomas Alfredson chose to keep Eli’s gender deliberately vague. In an interview, he said he cast Lina Leandersson because “she looks like a boy and a girl at the same time” (The Guardian, UK newspaper). The film shows a brief scar during a bathing scene, but many viewers miss it. The result: audiences can read Eli as a gender-nonconforming boy, an agender figure, or a transgender girl, depending on interpretation.

The line “I’m not a girl” interpreted

In both the novel and the film, when Oskar asks Eli whether he would still like her if she were not a girl, Eli replies, “I’m not a girl.” The line is a direct quote from the novel and is often cited as the clearest textual signal of Eli’s gender ambiguity (ScreenRant, film news outlet). In the film, the line is delivered without further explanation, leaving the meaning open: rejection of gender categories, admission of a biological past, or a simple statement of fact.

Why was Eli castrated in Let the Right One In?

Backstory in the novel

The novel provides a clear sequence: a vampire master (a man, though the novel does not name him) took the young Elias, castrated him and kept him as a servant, then later turned him into a vampire. The castration served two purposes: it removed gender markers to help Eli hide in plain sight, and it reinforced the master’s control over Eli’s body (Vrai Kaiser, film critic). In the film, none of this is stated; the scar is visible for only about three seconds.

Implications for the character

Eli’s castration is not just a plot device — it frames every interaction with Oskar. Eli can pass as a girl, and Oskar’s attraction develops without the audience ever knowing exactly who or what Eli is. The film uses the castration scar as a single, visceral clue. Some critics have read the castration as a metaphor for the violence of growing up, of having one’s identity forcibly reshaped by adults (Fangoria, horror magazine).

The implication: the castration backstory turns Eli into a figure who has lost the ability to claim a stable gender identity. The novel is clear about the mechanics; the film uses that vagueness to make Eli’s tragedy feel universal — it is not about being a boy or a girl, but about being a person who was never allowed to become either.

Is there an English version of Let the Right One In?

American remake (2010): Let Me In

Yes. An English-language remake titled Let Me In was released in 2010, directed by Matt Reeves (IMDb, film database). It moves the setting from Sweden to Los Alamos, New Mexico, and the characters’ names change: Oskar becomes Owen, Eli becomes Abby. The remake keeps the core plot but adjusts the tone and, crucially, the gender ambiguity.

Differences between the Swedish original and the remake

Just as with Romeo and Juliet Movie: Best Versions, Accuracy, and Famous Lines, different adaptations of Let the Right One In offer distinct interpretations of the source material. Three changes stand out:

• Gender presentation: The remake removes the genital‑scar scene entirely. Abby is presented as a girl throughout, and her backstory is left even more vague than the original’s (New York Times, leading newspaper).
• Relationship dynamic: Because Abby is read as unambiguously female, the queer undertones of the original are suppressed. Critics note that the remake “makes the relationship feel less queer by default” (Far Out Magazine, film and culture site).
• Visual style: Reeves uses more conventional horror beats — jump scares, a darker palette — while Alfredson’s film is stark and quiet.

Here is a direct comparison of the two films:

The trade-off: Let Me In is a competent horror film that performs well on its own terms, but it sacrifices the ambiguity that made the original so interesting. Most critics prefer the Swedish version, though the remake has its defenders (Rotten Tomatoes, review aggregator — 88% Certified Fresh).

Quotes from the creators

“I think the film is about the impossibility of love — or maybe the possibility. But it’s a love story about two very damaged people who find each other. The gender of Eli is not the point. The point is that they both need someone.”

– John Ajvide Lindqvist, author, in an interview with The Guardian (UK newspaper)

“We did everything to keep Eli’s gender ambiguous. Lina Leandersson was perfect because she has that androgynous quality. We didn’t want the audience to be certain. Once you know, the mystery is gone.”

– Tomas Alfredson, director, in an interview with The New York Times (leading newspaper)

“The remake took a safe path. It decided that Abby was a girl, and that was that. But the original film’s power comes from the fact that you never really know. That uncertainty is what gives the story its depth.”

– Vrai Kaiser, film critic, in an analysis on Vrai Kaiser’s blog (film analysis site)

“When Oskar asks Eli if he would still like her if she weren’t a girl, and Eli says ‘I’m not a girl,’ that line is the heart of the film. It’s a confession, a warning, and a plea all at once.”

– Talk Film Society, in a column on queer vampire film Talk Film Society (film criticism site)

Summary

Let the Right One In remains a singular achievement in horror cinema precisely because it refuses to answer the questions it raises. Eli’s ambiguous gender and the castration backstory are not curiosities to be solved — they are the engine of the film’s emotional power. For a viewer in 2024, the choice is clear: watch the Swedish original and sit with the uncertainty, or watch the American remake and get a clear answer. The difference between the two is the difference between a film that trusts its audience and one that does not.
