Story of Your Life → Arrival (2016)

Eric Heisserer and Denis Villeneuve keep Ted Chiang's central conceit, a linguist who learns to live time non-sequentially, and wrap it in an invented geopolitical thriller the calm, physics-literate novella never has.

Hannah's exact age at death is not stated as a precise on-screen number; secondary sources describing the film place it anywhere from about twelve to fifteen, so this record describes it only as early adolescence rather than citing a single disputed figure.

Some plot detail here (e.g., the precise cause of Louise and Gary's divorce in the novella) is unstated by the source rather than unresolved by our research; the record notes explicitly where the source is silent rather than guessing.

Fidelity

Higher = more of the source is still true. Fidelity is not quality.
Plot structure70The film keeps the novella's spine in order: recruitment, first contact, cracking the heptapods' written language, Louise's foreknowledge surfacing as she gains fluency, and the aliens' departure. The two structural changes with the most weight are how the future-daughter sections are told, restructured from a transparent, continuous parallel narration into a withheld twist revealed only in the third act, and the ending, where the novella's unexplained departure is replaced by an explicit reciprocal motive (the heptapods need humanity's help in 3,000 years). Both are reorderings of existing material, plus one outright replacement; the underlying spine stays intact, which keeps this axis in the high 60s to low 70s.partial evidenceN = 17 beats, source weight 31
Character54Louise keeps her vocation, her romantic arc, and the choice to have her daughter anyway, but the novella's wisecracking narrator becomes a solemn screen protagonist and the continuous second-person narration to the daughter is restructured into a withheld reveal. Gary becomes Ian in name, in a beard-and-corduroy appearance the film drops, and in plot function, since his novella-attested physics thread barely survives. The daughter goes from unnamed and dying at 25 in a climbing accident to named Hannah on screen and dying in early adolescence of an illness, foreclosing the adult-life material the novella depicts. Weighted toward the two leads (scores in the low-to-mid 40s and low 60s) with the daughter and Weber weighing in below and around the middle, the prominence-weighted mean lands just above the midpoint; Agent Halpern and General Shang, wholly new to the story, are excluded from this mean because there is no source claim to score them against.partial evidenceN = 5 people, weight 12
Dialogue & voice38The novella's defining device, a first-person present-tense fieldwork narration interleaved with a second-person future-tense address to the daughter, cannot survive translation to a visual medium as a continuous device; the film keeps only bookend voice-over fragments of it. Louise's wisecracking register on the page becomes a serious, restrained screen performance, and the recurring closing line that marks the novella's circular structure is replaced with a different one on screen. What does carry over is the institutional caution voice around the aliens (Weber's and, on screen, Halpern's insistence on revealing little) and the pattern of the heptapods answering questions about purpose with questions of their own. More markers convert or drop than survive, which keeps this axis low.partial evidenceN = 8 voice markers
Theme & tone50The claim that learning a language reshapes cognition, and that foreknowledge of loss does not stop someone from choosing love anyway, survives intact and is the film's emotional climax. What does not survive is the novella's hard-science frame: Fermat's principle of least time, load-bearing on the page, is reduced to a single passing reference to 'more advanced physics.' The tone shifts from a calm, interior, elegiac register to a geopolitical-thriller register built around a countdown to war, and the novella's determinism, that a fixed future forecloses real choice, is inverted into a film thesis about free will chosen in spite of foreknowledge. Half the tracked thematic claims survive unchanged and half are altered, an even split rather than a clear majority either way.partial evidenceN = 6 thematic claims
Coverage82Counting the novella's alternating present-tense (first-contact) and second-person future-tense (daughter) sections as source units, 14 of 17 tracked beats appear on screen in some form, including recruitment, the Heptapod A/B breakthroughs, the marriage and its end, and the daughter's foreseen death. Two beats do not appear at all, the daughter's teenage-independence and college-age years, which cannot be depicted once the film moves her death to early adolescence, and one is replaced rather than kept: the heptapods' unexplained departure becomes an explained one. Near-total presence of the spine supports a low-80s score.partial evidenceN = 14 of 17 source units present
Additions restraint70The film invents a geopolitical crisis absent from the novella entirely: the weapon/gift mistranslation, General Shang's ultimatum, the soldiers' bomb plot and the phone call that motivates it, Louise's phone call using Shang's private number and his wife's dying words, and Agent Halpern as a new CIA-liaison character. Counted against the 14 source beats that still appear in some form, 6 wholly invented beats bring this to 70; it is not higher because the additions are not small staging choices but an entire second plot layer running alongside the kept material.partial evidenceN = 14 source beats, 6 invented

Ending

Side by side, in our words.
On the page · Story of Your Life

Louise narrates, addressed throughout to her daughter in second person, future tense, the whole arc of a life not yet conceived: infancy, a fraught adolescence, early adulthood, and a rock-climbing accident that kills the daughter at twenty-five. Louise already knows all of this because fluency in the heptapods' non-linear written language lets her experience time the way they do. The heptapods' looking-glass devices eventually go dark without any stated reason for their visit or their departure, and Louise, already aware of the marriage that will end and the daughter who will die, agrees to conceive her anyway.

On the screen · Arrival

The film reserves this same knowledge as its twist: scenes that play throughout as memories of a daughter, Hannah, are revealed at the climax to be Louise's foreknowledge of a child not yet conceived, who will die of an incurable illness in early adolescence. The heptapods explain their reason for coming: they will need humanity's help 3,000 years in the future and are offering their language now in advance of that. Ian leaves once he learns Louise always knew what would happen to their daughter. Knowing all of it, Louise still chooses to have her.

The mechanism (foreknowledge through the heptapods' language), the failed marriage, and Louise's choice to have the child anyway are unchanged. What changes is the frame: the novella presents the choice as acceptance of a fixed, unalterable future, disclosed plainly across the whole text; the film restages the same information as a withheld twist and recasts the choice as an act of free will, and it gives the heptapods an explicit, reciprocal motive for arriving that the novella never supplies. The daughter's cause and age of death also change, from a climbing accident at twenty-five to an illness in early adolescence.

November 2016
Consulted, mixed
Around the film's release, Chiang said he was not actively involved in the adaptation process and was fine with that distance, saying he did not need the film to conform to a specific vision of his own; he credited screenwriter Eric Heisserer's persistence, noting Heisserer had written close to a hundred drafts over roughly five years.

Eric Heisserer
screenwriter
November 2016
Participating adapter
Heisserer said his first, faithful pass at adapting the novella only got him halfway, because Chiang's remote, screen-based first contact produced a flat narrative without dramatic peaks and valleys; he described deliberately inventing the physical arrival of the ships, the Ian Donnelly relationship material, the military bomb plot, and the General Shang crisis to give the story a dramatic shape, while shifting the ending's emphasis away from the novella's account of human selfishness and toward collaborative hope.

Denis Villeneuve

December 2016
Participating adapter
Villeneuve said he found the short story 'beautifully intellectual' but structurally repetitive and without dramatic shape on its own, and credited Heisserer's screenplay with solving that; he confirmed the physical landed spacecraft were his and Heisserer's addition, since the novella has the heptapods appear only through remote screens, and said he changed the title from Story of Your Life because it read to him like a romantic comedy rather than a science-fiction film.
