Frankenstein (2025): How to investigate an adaptation without reducing it to fidelity
The credits confirm that Guillermo del Toro wrote and directed a film based on Mary Shelley; that does not settle what it takes from the book or what it transforms. This AI-assisted analysis distinguishes what is documented from what requires direct viewing and remains subject to editorial verification before publication.

The useful question to ask about Frankenstein (2025) is not whether Guillermo del Toro was faithful to Mary Shelley, as though fidelity were a final grade, but what specific relationship can be demonstrated between two distinct works. The production credits identify del Toro as the writer and director and credit the film as based on Shelley’s book; Netflix also presents it as a new version of her story. That evidence allows us to call the film an adaptation. By itself, it does not allow us to conclude that the film reproduces the novel, summarize its differences or attribute a more precise intention to its filmmaker. To make progress without confusing a credit, a statement and an analysis, it helps to begin with a verifiable formal choice: the film structures its narrative around more than one perspective. The 1818 novel also contains nested narratives, but distributes the voice differently. Comparing those frames opens up a reading of who has the right to tell this story, without making resemblance to the book a measure of value.
First, identify the work, not the myth
The title Frankenstein may refer to the novel, Victor, the creature, other films or the cultural imagination that has accumulated around all of them. So before making a comparison, the subject needs to be clearly defined: here, it is the 2025 film written and directed by Guillermo del Toro, starring Oscar Isaac as Victor Frankenstein and Jacob Elordi as the creature. Netflix lists a running time of two hours and thirty-two minutes and describes it as a new version of Mary Shelley’s story. Netflix’s presentation confirms the general attribution; the film’s production-design documentation gives the credit more specifically: “Based on the book by Mary Shelley”.This is no minor formality. A resemblance to James Whale, stage adaptations or the popular image of the “mad scientist” does not, by itself, show that a passage comes from Shelley. Nor does the title establish that the film follows a particular edition of the book. The unit of analysis must remain del Toro’s film, not the collection of images the public already associates with Frankenstein. If an article wants to claim that a scene changes, preserves or relocates an episode from the novel, it needs to identify both versions and compare concrete evidence, rather than rely on the monster’s place in the collective memory.
The material consulted confirms the film’s identity, credits and literary source, but it does not replace the complete film or a scene-by-scene record. The reading that follows is therefore limited to structural aspects described by identifiable sources; it does not present observations from direct viewing as if they were the writer’s own.
The connection to Shelley is documented; its terms are not a quality label
The connection to the novel is established in official materials and in del Toro’s statements. In an interview published by Netflix, the director discusses translating Shelley’s rhythms for the screen and his aim of recovering the anxiety he associates with the book. In another conversation, he explicitly connects the film with the relationship between creator and creature and with the creature’s growth. These statements are valuable evidence of an intention articulated by the filmmaker, but they do not automatically prove that every formal choice achieves that aim or that the result is faithful to every element of the novel.Del Toro has also described the project as the product of a personal, longstanding relationship with the material. In an interview with TheWrap, he explains that he hoped to recapture the impression of encountering the characters before they became cultural icons. That statement helps frame an analytical question: what does the film do to distinguish its story from versions already familiar to audiences? It does not justify claiming, without examining the film, that it succeeds. An interview records an intention; analysis of the work must show what resources are used to realize it—or where that aspiration comes into tension with other elements.
Thus, “based on the novel” describes a documented connection, not a promise of transcription or a critical verdict. And “faithful” requires specifying the object of comparison: plot, narrative structure, characterization, theme, tone or a particular edition. Without that specification, the word conceals several different questions beneath a single scale.
A productive contrast: who tells the story
A particularly relevant place to begin comparing the works is their narrative architecture. Reviews published after the film’s presentation describe an opening in the Arctic and a narrative that moves first through Victor and then through the creature. A review in Le Monde specifies that Victor tells his story to a sailor, after which the creature takes the floor. Netflix’s official interview confirms that the film works with two perspectives, though the specific account of its structure should be checked against the film itself before attributing effects to its editing or staging.Mary Shelley’s 1818 text offers a documented point of comparison. The novel opens with Captain Robert Walton’s letters to his sister, Margaret Saville. Within that epistolary frame, Walton passes on Victor’s story; the creature, in turn, recounts its experience to Victor. The novel does not provide a neutral voice that certifies everything that happened: the stories reach us mediated by different narrators and by the chain that transmits them. The Shelley-Godwin Archive documents the importance of Walton’s letters to the composition and opening of the novel published in 1818.
The critical question is not whether the film reproduces that structure “correctly,” but what changes when a narrative nested within letters is brought to the screen and organized, according to the sources consulted, in two stretches associated with its protagonists. Whom does the frame grant authority? Does the creature’s account correct Victor’s, expand it or leave the two in conflict? Only a direct comparison of scenes, voices, transitions and ending can answer these questions. The documented structure makes them possible to investigate; it does not answer them on its own.
The novel, too, requires a choice of edition
“Shelley’s novel” does not always refer to exactly the same text. The first edition appeared in 1818; Shelley published a revised version in 1831. The Shelley-Godwin Archive gives the date of the original publication and preserves materials from the manuscript process. For a precise comparison, the edition being used needs to be stated, and the wording of one should not be mixed with that of the other without notice. The digital edition of Project Gutenberg consulted here says that it transcribes a reproduction of the 1818 edition, making it an identifiable reference for this comparative framework.The choice matters because an adaptation may relate to a particular textual version, to a later editorial tradition or to elements that circulate in the culture without literally deriving from any of them. Accordingly, a responsible formulation would not simply be “the film changes the book,” but something like: “At this point, the film is being compared with the corresponding passage in the 1818 edition.” If that correspondence has not been established, the claim should remain a hypothesis.
This method also helps avoid a false opposition between a supposedly fixed novel and a supposedly wayward film. The text itself has a history of publication and revision. That does not remove the responsibility to identify the source or make comparison useless. On the contrary, it makes it possible to ask more precisely what textual object is being adapted and what follows from reading it alongside a later film.
From stated intention to critical reading
Del Toro’s interviews offer clues to the project’s orientation: he discusses the book’s anxiety, his own connections to the myth and an interest in the relationship between parents and children. Netflix also presents parenthood as a central element of its interpretation of the film. It is legitimate to examine how that framework engages with Shelley; it is not legitimate to state as fact that every aspect of the film was conceived to express a single thesis. A director can name an intention, but the work may produce tensions or meanings that exceed that statement.Moving from intention to interpretation requires verifiable observations of the film. On a second viewing, an analysis might record, for example, when the narrative’s centre shifts, what information audiences receive before or after each narrator speaks, and what visual and sound choices accompany those shifts. The corresponding passage in the selected edition of the novel could then be located. Each note should distinguish three levels: what appears or is heard; what an external source reports about production or intention; and the interpretation proposed by the writer.
Without such a record, it is possible to describe the general structure reported by critics and official sources, but not to rigorously attribute effects to a shot, sequence or sound design. An independent review can provide context and suggest hypotheses; it cannot replace either viewing the film or consulting the literary text. This distinction limits the article’s scope, but it also prevents a claim that sounds convincing from being mistaken for evidence.
What can be concluded—and what remains open
The evidence consulted supports three limited conclusions. First, Frankenstein (2025) is a film written and directed by Guillermo del Toro and credited as based on Mary Shelley’s book. Second, the director has spoken publicly about his relationship with the novel and specific interpretive intentions; those statements document his perspective but do not guarantee a single reading of the film. Third, the sources consulted describe a structure of perspectives that can be brought into dialogue with the nested narration of the 1818 edition.That dialogue offers a more fruitful path than asking whether the film “is faithful.” It makes it possible to investigate how the mediation of the story changes when we move from Walton’s letters and Shelley’s embedded narratives to the cinematic organization described by the sources. It also requires us not to attribute every cultural image of the monster to the book, or to turn the director’s statement into a complete explanation of the film. The outcome of the comparison may be an interpretation, not a score.
Questions remain that require direct inspection of the complete film: how shifts in perspective are constructed in specific scenes, which elements of the novel are preserved or rearranged in those passages, and what formal effects accompany the differences. Until that work is documented, it is not appropriate to assert details of staging, issue an overall judgment of fidelity or attribute a definitive intention. Comparison is a method for understanding choices, not a shortcut that replaces analysis of the film.
