The Noise Has to Survive the Mix
A Case Study of Ingen tid å miste (The Killjoy) (2022)
“The recording begins as noise. It becomes a memorial when Elise decides which part deserves to survive.”
The Atlantis Awards Case Studies are not reviews. Their purpose is to examine the craft behind exceptional filmmaking—celebrating successful creative choices and identifying the mechanics behind why they work.
This article discusses the film’s plot in detail, including its ending. It also references the death of a pet.
A Note on Sourcing: The Killjoy is a festival-submitted short without the surrounding ecosystem of trade press, interviews, or production journalism this series usually draws on to verify department-level craft claims. This essay is built from direct, shot-by-shot and line-by-line analysis of the film itself, corroborated where possible against the director’s official submission materials and confirmed festival listings. No additional filmmaker commentary was available before publication. Undocumented interpretations below, including several specific readings of the film’s final images, are presented as critical readings of the finished film rather than confirmed statements of intent.
Late in the film, Elise opens a folder on her laptop labeled jævla nabo — Norwegian for something close to “goddamn neighbor.” Inside are recordings she made earlier: a dog playing, running, panting, thumping against a floor through the wall of her apartment. The folder name suggests that she preserved them as evidence of an annoyance, not as a keepsake.
By the time she opens that folder again, the dog is dead, and the man next door can no longer hear him.
That reversal is the entire film compressed into one object. Elise spends The Killjoy deciding, professionally and instinctively, what counts as signal and what counts as noise. The film’s real achievement is that it never asks her to abandon that instinct. It asks her to apply it somewhere she never thought to before — to the sounds crossing through her own wall from a life she’d stopped considering a life at all.
A Forest Built From Separate Sounds
The film opens inside what looks like a complete world: a man walks through trees at dusk, finds a woman, and the two embrace in a field lit by a low sun. Cinematographer Petter Brenni Gulbrandsen shoots it as a finished piece of cinema — composed, graded, scored. Then the film cuts to Elise, headphones on, in a sound studio, and everything we just watched changes status. The forest stops functioning as a complete environment and becomes a set of acoustic decisions still being made — footsteps, wind, birds, breath, each one sitting in its own file, waiting to be assembled into something that will eventually feel like it was never assembled at all.
Elise is good at her job specifically because that assembly disappears. The whole opening sequence exists to establish the stakes of everything that follows: her professional skill is measured by how completely an audience stops noticing that a world was built rather than recorded.
Silence Is a Work Condition
Construction noise in her building makes the studio unusable after a certain hour. A colleague has to leave. The client screening has already been promised for the next morning, and when Elise checks in on the mix, the director is warm about what he’s heard but the conversation makes clear the work isn’t finished and the deadline isn’t moving. She has to take the project home.
Her apartment becomes a miniature production facility. Drop cloths cover the floor. A wooden box filled with dirt and grass sits in the middle of the living room, boom mic rigged directly above it, so she can walk through it in place of a proper Foley pit. Cables run across the room to a laptop balanced on the arm of a couch. Production designer Anna Øihusom’s apartment doesn’t read as a generic home standing in for a studio — it reads as the forest itself, disassembled and smuggled indoors one material at a time: soil underfoot, grass, a large indoor plant crowding the frame, fabric and household surfaces standing in for whatever the professional studio would normally provide. The film is quietly rebuilding its own opening image inside a space that was never built to contain it.
That’s the first real inversion the film sets up. A woman whose entire job is creating a convincing, controllable reality is placed inside a reality — her own home, her own neighborhood — that she has no ability to control at all.
The Neighbor Exists Before We See Him
Mathias enters the film as sound before he enters it as a person. Elise hears music through the wall, stops working, and goes to his door to ask him to turn it off — “I kind of need total silence,” she tells him, and he obliges. Later, in a small structural rhyme worth noticing, the direction reverses: he comes to her door, having bumped a wall while moving furniture and knocked a framed photo to the floor, offering an apology she didn’t ask for. The same doorway hosts both a demand and an apology, and the film never overplays the symmetry — it just lets the two visits sit across from each other.
Before any of that, though, there’s the dog. Elise experiences whatever is happening in the neighboring apartment purely as acoustic residue — thumping, playing, barking — stripped of any context that would let her understand it as somebody’s actual life rather than an interruption to hers. That’s not a flaw in her character. It’s the ordinary, unremarkable way anyone processes a neighbor’s noise. The film is quietly building the conditions for its own reversal: she can only classify what she can’t see, and what she can’t see, she classifies as noise by default.
Realism Can Be Manufactured
Elise’s toolkit is layered and specific. She has stock effects on her laptop — footsteps, impacts, prefabricated sound she can drop into a mix. She performs Foley herself, stepping through the dirt box in sync with a body on screen. When she needs a specific kind of masculine physical effort for the track, she recruits Mathias directly, on the reasoning that a male performer producing the exertion live will sound more convincing than her own voice processed toward the same result.
Then there’s the panting. Mathias hears it in her mix and tells her it sounds real — “that is me panting, not an actual dog,” she has to correct him, because what he’s identifying as a convincing animal is actually her own breath, close-miked and shaped until it reads as something else entirely. That’s the film’s first hinge, delivered almost as a throwaway line: her fabrication has succeeded completely by the only standard her profession normally uses. The image and the sound match. Nobody would ever know the difference.
Except Mathias does know a difference — not between fake and real sound, but between a competent generic dog and the specific one he actually lost.
The Cut Places the Listener Inside the Mix
Later, Elise plays him a section of the finished mix, headphones on, eyes closed. Mathias closes his eyes in Elise’s apartment, and editor Petter Sørum Hagen does something more formally exact than a line of dialogue could manage: the next cut places him inside the forest footage, occupying the cinematic world whose sounds he is hearing. The living room furniture travels with him — Elise’s table and laptop, the couch he and Mathias were just sitting on, restaged among the trees, with the two actors from the inner film walking through that same physical arrangement. For a few seconds, Mathias isn’t a man listening to a mix. He’s inside it, exactly the way an audience is meant to be, and the cut takes Elise’s workspace with him to prove it.
Then Elise triggers the panting cue, and everything changes at once. His expression breaks — not dramatically, just a flicker of something he can’t fully suppress — and his hand goes up to the headphones. He pulls them off. He’s back in the apartment. The transportation the whole film has been quietly building toward as a professional achievement becomes, in this exact instant, a personal wound. The sound worked too well. That’s what breaks him open enough to tell her, a few moments later, that his dog got sick a few days ago and didn’t recover.
Silence Means Something Different Next Door
“It’s like losing a member of your family,” Mathias tells her, and the line reorganizes everything the film has shown up to that point. The silence Elise has spent the whole film chasing as a professional necessity is the same silence Mathias has been living inside as evidence that Leo is actually gone. They were never simply on opposite sides of a noise complaint. They were experiencing the identical acoustic condition — quiet, empty air where sound used to be — as two entirely different facts about the world.
Mari-Elene Gudahl’s performance carries that reclassification without ever pushing it. Elise doesn’t become visibly sentimental. Her irritation gives way to attention first, and only later to something that looks like recognition. The film lets the new information change how she’s thinking before it asks her face to show anything at all.
The Nuisance Becomes the Archive
The deadline moves earlier rather than later. Elise now has less time than she expected, but instead of returning immediately to the project, she asks Mathias whether he would like to try something. She places the headphones on him, asks him to close his eyes, and opens the folder carrying the name she once gave his household when it existed to her only as interference.
She did not preserve these sounds because she believed they mattered. She preserved them because they were intrusive enough to be worth cataloguing. The motive behind the archive was dismissive. The archive itself didn’t care what the motive was. It kept Leo anyway, indifferent to why it was built, right up until the moment its indifference became the only reason Leo still exists in any recoverable form at all.
The Sound Returns Without the Body
Elise doesn’t tell Mathias what she’s found. She has him lie down and close his eyes, the same posture he was in during the earlier session, before she knew what she was about to give him. She works in real time, visibly cleaning the recordings up on screen as they play, the noise-reduction tool doing literally what it was built to do: isolating a signal from everything surrounding it. Only now the surrounding interference is the noise, and Leo — panting, playing, alive — is the signal she’s trying to recover.
His reaction is the film’s most disciplined choice. He doesn’t cry. He doesn’t break down. There’s the faintest hint of a smile, something close to appreciation, and the smallest visible quiver in his jaw before he can steady it. Elise watches him react and allows herself, quietly, to smile too.
Then the image itself gives up. Rather than holding on his face for the emotional payoff, Sørum Hagen’s cut moves away and up — into the leaves of the apartment foliage that has visually echoed the forest throughout Elise’s home setup. The picture goes soft and abstract. What’s left is only the sound of Leo, happy and healthy, still playing.
That’s a genuinely disciplined final choice, and it’s worth being precise about what it actually does. The film has spent its whole runtime proving that sound alone can restore a body no image will ever show us again — Leo is never once seen on screen, dead or alive, so his entire existence in this film is acoustic from the very first mention of him. Ending on an unresolved, out-of-focus image, with no face left to watch reacting on our behalf, refuses the audience the easy version of catharsis: watching someone else feel something. Instead we’re left holding the processed recording itself, separated from any image that could tell us how to receive it. The film doesn’t show us that sound can transport somebody. In its very last seconds, it tries to do the same thing to us directly.
Ådne Lyngstad Nilsen’s score supports the sequence through sustained, unhurried movement rather than a sudden emotional peak. It remains present without replacing Leo’s recorded breathing as the scene’s central sound. The music never tells the audience the moment is enormous. It simply stays present, the way Leo’s recorded breathing stays present, until the image lets go and only the sound is left to carry the rest.
The Cost of Saving the Noise
This method creates real costs, worth stating plainly rather than folded quietly into admiration for the craft.
The archive was never consensual. Elise recorded sound crossing through her wall from Mathias’s apartment without his knowledge, filed it under a hostile label, and kept it. Her intentions changing after the fact — from irritation to compassion — makes the eventual use of those recordings feel like a gift. It doesn’t retroactively make the original act of recording anything other than what it was: documentation of a neighbor’s private life, made and stored without his permission or awareness.
The gift remains unilateral. Elise asks whether Mathias wants to try something, but she does not appear to explain that she has preserved private sounds from his apartment or that he is about to hear Leo. The surprise becomes compassionate because his response is positive. It could just as easily have overwhelmed someone whose loss occurred only days earlier. The same confidence that makes Elise effective at guiding an audience’s emotional experience also allows her to decide when Mathias should encounter his own grief through sound.
The ending may be cleaner than actual grief tends to be. Hearing a recently lost pet again could just as easily reopen a wound as soothe one. The film’s own restraint — no breakdown, just a held smile and a suppressed quiver — protects it from feeling falsely tidy, but it’s worth naming honestly that the film chooses the version of this moment that comforts rather than the version that might complicate. That’s a legitimate artistic choice. It’s also a choice, and it shapes how easily the ending is allowed to resolve.
Access to Mathias’s interior life remains limited until the film needs it. For most of the runtime, he exists to Elise, and to us, primarily as noise, then as a useful vocal performer, then as the source of a revelation. His grief, once it appears, is handled with real care. But the structure of the film still routes his loss through what it does for Elise — her deadline, her craft, her recognition of a judgment she’d never applied to the people around her.
Closing
The Killjoy begins with a woman who has built her career on making other people stop hearing the labor behind a sound. It ends with her redirecting that same skill toward one specific listener — removing the interference around a recording until the life inside it becomes audible again.
The software cannot know what matters. It can only suppress frequencies according to the parameters Elise gives it. She is the one who decides that the sounds surrounding Leo are now interference and that the animal she once filed under “goddamn neighbor” is the signal worth recovering. Her craft has not changed. Her judgment has.
The film’s final image drifts away from Mathias and loses focus while Leo remains audible. There is no photograph of him, no flashback, and finally no face left to tell us what the sound means. The mix cannot return the body. It can refuse to let silence become the only evidence that he was there.
