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.Ending
Side by side, in our words.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.
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.
Mapping
18 rows. Every source unit, including the ones that never appear.| Source unit | What happens there | On screen | Notes | Tag | Evidence |
|---|---|---|---|---|---|
| Present thread: Colonel Weber recruits Louise | An army colonel brings Louise a recording of heptapod speech and asks her to help decode it, warning her to reveal as little about humanity as possible. | Film, opening act, Weber's visit to Louise's campus | kept; the recruitment beat and Weber's information-caution both carry over | strong | |
| Present thread: first exposure to the heptapods at the 'looking glass' | Louise and physicist Gary Donnelly meet the two heptapods, nicknamed Flapper and Raspberry, through a remote two-way viewing screen at a US site. | Film, first visit to the Montana 'Shell' | kept, delivery mechanism changed; the novella's remote video screen becomes a physical, landed spacecraft the humans enter and the heptapods (Abbott and Costello) are seen through a fog-filled barrier rather than on a monitor | primary | strong |
| Present thread: early analysis of Heptapod A (spoken language) | Louise begins building a working vocabulary and grammar of the heptapods' spoken language through methodical fieldwork. | Film, early linguistics montage | condensed; the fieldwork process is compressed into a short sequence | partial | |
| Present thread: Heptapod B discovered to be a separate, semasiographic written language | Louise realizes the heptapods' writing is not a transcription of their speech but an entirely different, whole-sentence pictographic system. | Film, ink-circle whiteboard breakthrough sequence | kept; one of the story's central discoveries survives intact and becomes a signature visual sequence | primary | strong |
| Present thread: military caution about disclosing information to the heptapods | Weber and the wider military effort limit what Louise and Gary may ask or reveal, wary of tipping their hand. | Film, ongoing site restrictions | condensed; the film splits this function between Weber and the added Agent Halpern | partial | |
| Present thread: Gary's physics thread and Fermat's principle of least time | Gary's parallel discovery, that Fermat's principle describes a physical process 'knowing' its endpoint in advance, mirrors and helps explain Louise's own linguistic breakthrough. | Film, single reference to the heptapods' interest in 'more advanced' physics | condensed heavily; a sustained explanatory thread is reduced to a passing line | strong | |
| Present thread: fluency in Heptapod B reveals whole-sentence, non-sequential meaning | Louise learns that Heptapod B logograms are composed with foreknowledge of the entire statement, the discovery that unlocks her own experience of time. | Film, Louise's escalating comprehension across the second act | kept; the core conceit of the source survives as the film's own central discovery | primary | strong |
| Present thread: Louise's foreknowledge of her daughter's life surfaces as her fluency grows | As Louise's Heptapod B fluency deepens, she begins to experience memories of her daughter's future transparently, addressed to the reader throughout the text. | Film, the recontextualized 'flashback' sequences | reordered; the same mechanism is restructured as a withheld twist revealed only near the climax rather than disclosed as it happens | primary | strong |
| Present thread: the heptapods' looking glasses go dark and the aliens depart unexplained | The heptapods stop responding and their looking-glass devices fall silent; the novella never states why they came or why they leave. | Film, the heptapods' explained departure | replaced; the film supplies an explicit motive (the heptapods will need humanity's help in 3,000 years and offer their language now in exchange) that the source withholds entirely | strong | |
| Future thread: the conception-night frame | The narration is retrospectively addressed from the night of the daughter's conception, a fact the text establishes early. | Film, the reframed opening and closing scenes | reordered; the film withholds this timing until the climax instead of establishing it upfront | primary | partial |
| Future thread: infancy and early childhood | Early vignettes of the daughter's infancy and toddler years. | Film, flash-forward montage fragments | condensed | partial | |
| Future thread: childhood and Louise's rapport with her daughter | Childhood scenes carry the novella's wry, joking rapport between Louise and her daughter. | Film, childhood flash-forward scenes | condensed, tonally altered; the scenes appear but the wisecracking register belongs mostly to the prose voice and is muted on screen | partial | |
| Future thread: the marriage's eventual end | The text establishes that Louise and Gary will marry and later divorce, without stating a cause. | Film, Ian's departure after learning the truth | condensed, cause added; the fact of the split survives, but the film gives it an explicit trigger (Ian learning Louise always knew about their daughter) that the novella leaves unstated | strong | |
| Future thread: the daughter's teenage years and growing independence | Scenes of the daughter as a teenager pulling away from Louise. | omitted | omitted; the film's daughter dies before reaching this stage of life | partial | |
| Future thread: the daughter's college years and early adulthood | Scenes of the daughter as a college student and young adult. | omitted | omitted; the film's daughter dies before reaching this stage of life | partial | |
| Future thread: the climbing accident and death at twenty-five | The daughter dies at twenty-five in a climbing accident, a fact Louise has known since before conception. | Film, Hannah's death from an incurable illness in early adolescence | condensed, cause and age altered; the foreknown death survives as the story's central loss, but its cause and the daughter's age both change | primary | strong |
| Future thread: the aftermath of the daughter's death | Louise's grief and the practical rituals following her daughter's death. | Film, compressed grief imagery in the final act | condensed; a specific aftermath scene becomes brief, non-specific imagery | thinnot scored | |
| Future thread: closing reflection on choosing to have the child | Louise closes by affirming she will conceive her daughter regardless of what she already knows, framed as an acceptance of a fixed future rather than a free choice. | Film, closing voice-over and final scene with Ian | condensed, reframed; the choice itself survives as the film's ending, but the film frames it as an exercise of free will rather than acceptance of determinism | primary | strong |

People
Trait score = attested traits kept ÷ attested traits shown. Unstated traits are not rows.Louise Banks63
The vocation, central romantic arc, and the choice to have her daughter anyway all survive. What is lost is the specific literary register (wisecracking, continuously narrating in second person) and the explicit physics framing of her own discovery.
| Vocation / role | A linguist recruited by the military to help communicate with a newly arrived alien species. | preserved |
| Personality | Narrates in a wry, often wisecracking register.the screen Louise is played as solemn and restrained rather than dryly funny | altered |
| Relationships | Falls in love with and has a daughter with her physicist colleague. | preserved |
| Relationships | Marries the physicist and the marriage later ends.the fact of the split is kept; the film adds an explicit cause the novella never states | preserved |
| Plot function | Gains the ability to experience time non-sequentially by achieving fluency in the heptapods' written language. | preserved |
| Moral code | Knowingly chooses to have her daughter despite already knowing the daughter will die young. | preserved |
| Voice | Narrates continuously in second person, future tense, addressed to her daughter, interleaved throughout with the present-tense first-contact narration.the device survives only as bookend voice-over lines; the sustained interleaving becomes a withheld third-act reveal | altered |
| Plot function | Her breakthrough is explicitly paired with, and partly explained by, her partner's parallel discovery in physics (Fermat's principle of least time).the physics parallel is reduced to a single passing reference; her breakthrough on screen is presented as linguistic alone | altered |
Gary Donnelly → Ian Donnelly43
His role and rapport with Louise carry over. The losses are his name, his attested appearance, the specific physics thread that is his main contribution to the story's ideas, and the explicit new cause the film gives for the marriage ending.
| Identity | Named Gary Donnelly.renamed Ian Donnelly on screen for reasons no consulted source explains | altered |
| Vocation / role | A physicist assigned to work alongside Louise on the heptapod problem. | preserved |
| Appearance | Bearded and mustached, dressed in corduroy, reads as an academic on sight.the screen Ian does not carry this description | altered |
| Relationships | Becomes romantically involved with Louise, and they have a daughter together. | preserved |
| Relationships | The marriage will end, for a reason the text never states.the film gives this an explicit cause: Ian leaves on learning Louise always knew their daughter would die | altered |
| Plot function | Supplies the parallel physics discovery (Fermat's principle of least time) that helps explain Louise's own breakthrough.reduced to a single passing reference in the film | altered |
| Personality | Easygoing and unselfconscious, works comfortably alongside Louise. | preserved |
The daughter → Hannah40
The central fact that survives is the one the whole story turns on: her mother knows she will die young and has her anyway. Her name, her cause and age of death, and the adult life the novella depicts for her do not survive.
| Identity | Never given a name; addressed only as 'you' throughout the narration.named Hannah on screen | altered |
| Body / ability | Dies at twenty-five in a rock-climbing accident.dies of an incurable illness at a much younger age (secondary sources estimate early adolescence, without agreeing on an exact number) | altered |
| Plot function | Her mother foreknows her death from before conception and chooses to have her regardless. | preserved |
| Relationships | Conceived and raised by Louise and her physicist partner, whose eventual separation her future recontextualizes. | preserved |
| Arc | Lives through childhood, adolescence, and early adulthood, shown in vignettes spanning her whole life.the film forecloses this arc by having her die as a child | altered |
Colonel Weber75
His role and his information-control stance both carry over closely; what softens is his personal edge.
| Vocation / role | The military officer who recruits and oversees Louise and Gary's work with the heptapods. | preserved |
| Personality | Insists that the scientists reveal as little information as possible to the aliens. | preserved |
| Personality | Consistently suspicious of the heptapods and impatient with the pace of the scientists' progress.the screen Weber (Forest Whitaker) is played with more warmth, described by reviewers as a father-figure presence rather than a purely adversarial one | altered |
| Plot function | Oversees the on-site military effort to communicate with the heptapods. | preserved |
The heptapods → Abbott and Costello50
The species' core linguistic premise and general anatomy survive; their nicknames and how much of them is actually shown do not.
| Appearance | Seven-limbed, radially symmetric bodies with no fixed front or back. | preserved |
| Appearance | Clearly visible, gray, ridge-skinned barrel-shaped bodies seen directly through the looking glass.on screen they are shrouded in mist behind a translucent barrier, visible mostly as a single limb | altered |
| Voice | Communicate in two unrelated languages: a spoken Heptapod A and a separate written, whole-sentence Heptapod B. | preserved |
| Identity | Nicknamed by the human team Flapper and Raspberry.nicknamed Abbott and Costello on screen | altered |
Agent Halpernn/a
Wholly new to the adaptation; the novella has no intelligence-agency character of any kind.
| Vocation / role | A CIA liaison embedded at the Montana site alongside the military. | not depicted |
| Personality | Skeptical of Louise's slow, linguistic approach and inclined toward more forceful tactics. | not depicted |
| Plot function | His phone is the one Louise takes to make the crucial call to General Shang. | not depicted |
General Shangn/a
Wholly new to the adaptation; the novella has no international or military-crisis dimension at all.
| Vocation / role | The Chinese general commanding that country's military response to the heptapods. | not depicted |
| Plot function | Moves to attack the heptapods after a mistranslation reads their message as offering a weapon, reversing course only after a phone call from Louise. | not depicted |
| Relationships | His late wife's dying words become the private detail Louise uses, learned from her own future memory, to convince him to stand down. | not depicted |
Creator stance
Time-stamped. Co-creators are never collapsed.No other adaptation of this source is catalogued.
