How Denis Villeneuve Weaponizes Sound in DUNE transcript

To direct a truly cinematic film, a director must understand that sound is not a post-p production afterthought. For Denise Felv, sound design is the ultimate storytelling weapon. >> First of all, I think that sound is by far, if not the most powerful tool in the in the cinematic language, meaning that also for the theatrical experience. >> To achieve this higher level visual and acoustic synthesis on screen, a filmmaker cannot simply wait for the shoot.

You must begin designing your entire auditory environment during the first screenplay phase. >> And I uh I will say that I'm trying at my best in the past recent years I did my best to uh um think about the sound in the early development of the screen. >> For Velouv in standard Hollywood workflows, sound is treated as a cheap add-on applied only at the very end of production. This represents a massive frustrating artistic failure that Velnu struggled with during his early career. >> And a thing that I I love as as a uh that I suffered a lot when I was working earlier as a indie filmmaker.

I I was feeling that sound was coming really at the end of the process. >> To overcome this frustration, a director must integrate their acoustic ideas during the screenwriting and prep phases. This allows you to deploy original customized sounds that directly influence your individual picture editors, cuts and structural story timing. >> And I tried to bring it earlier even in screenwriting, but even then in in prep and in as we are doing production uh to have a team of artists that start to design sounds uh uh to feed the editing room.

By using this process, the visual and acoustic edits influence one another in the cutting room. >> Because uh um in in the editing room, I think that the the sound is as important as as the image. >> This collaborative workflow constructs a permanent sonic road map that is directly baked into the edit's DNA. It guides your final mix to ensure your theatrical audience experiences a truly unified, wonderful cinematic masterpiece.

We try to create a road map for the team that will inspire them and help them to mix the fimulator. That is something that is embedded in the DNA of the of the cut. >> To design a believable sci-fi universe, the director must reject artificial and synthetic shortcuts. Deni Elnuv and his sound department realized that Arachus' sensory soul was found entirely in the sand, requiring a completely organic field recording process to ground every scene. >> Dune is all about the sand.

I felt straight away we're not going to be asking the Foley stage to record this. So, the first thing I tried doing was sticking a a microphone underneath the sand and walk around it. This technical discovery completely redefined how the crew approached sound recording in the desert rather than treating sand as a silent sterile backdrop. They realized that a giant dune acts as an enormous musical instrument. >> And I realized that a sand dune is a resonant body.

You can hear someone walking 100 m away. So we then returned to the desert later and made a whole bunch of recordings together. >> By burying customized microphones in the deep desert sand under specific climate and temperature conditions, they captured an extraordinary novel acoustic phenomenon. These large shifting masses of sand can vibrate to create ancient deep and beautiful whaleike groans on the screen. Theo in those those early experiments had captured what we found was a a really novel sound that most people aren't aware of and that is that sand itself in large masses at the right humidity and temperature makes these beautiful whaleike groans.

To document these surreal textures, the sound team conducted a series of daring field experiments. They traveled to practical desert locations, deploying specialized recording equipment and submerging different types of microphones deep inside the sand to capture the complex hidden and unpredictable acoustic rumbles of the shifting sand dunes. So, we knew that we had to go out of the desert and play. And uh we took we took all types of microphones.

We took the type of microphones that you can put underneath the sand. Um we took regular microphones and protected them as well and put those underneath the sand. These underground recordings served a vital narrative purpose in the film. By capturing these organic sand vibrations, Felnu and his sound designers created the physical template for the giant sandworm, ensuring its mechanical movements felt heavy, powerful, and terrifyingly real on screen.

We put hydrophones underneath and recorded those resonances from underneath uh as we hit the sand, as we moved things around in the sand. And we also try to imagine how does that sand worm actually move through the sand? Is it does it vibrate and the sand particles kind of liquefy as it moves? By taking those bold acoustic risks, Velnu teaches us how to find visual and sonic inspiration in nature. Meticulous preparation and practical experimentation allowed a filmmaker to capture genuine organic textures, bringing their spectacular fictional world to life on the big screen.

And we spent a couple of days in Death Valley burying microphones to capture thumper sounds and things like that. But we also did a number of really kind of cool furrowing sounds. We we would take microphones and kind of jam them through the sand and as if mimicking the the worms motions. To design vehicles of an alien world, a director must move beyond standard industrial designs and ask how a future society would solve transportation without advanced computers.

When tasked with creating the iconic ornithopters for Arachus, Deny and his supervising sound editor Mark Manini had to design a machine that flapped like an insect. This unfamiliar mechanic presented an immense acoustic challenge as they had to invent a believable real working propulsion system completely from scratch. >> Theo and I began to maybe parse who's who was going to be responsible for what and somehow Ornithopters fell to me.

I was terrified because these it's it's it's an unknown method of transportation and it uses wings and we don't even know what the propulsion is. I don't know if there's a battery or a motor or a couple of bugs in a box in there. I'm I'm not quite sure what it was. >> To achieve sonic authenticity, Belu insisted on a gritty realness, he rejected standard synthesizer tones and digital libraries, establishing a strict rule that every sound must originate from an organic acoustic source to ground Arachus in a believable physical reality.

This guided their efforts. We wanted anything that we created to feel as though if you were actually there, that's exactly what it might sound like. You it was a believable universe of science fiction and that was always an overarching driver to the experiments that we would make. To make the futuristic ornithopters feel believable and powerful, the sound designers developed an incredibly unique acoustic recipe. They wanted to capture the physical rapid vibration of wings, choosing to close mic organic materials to ensure the technological motion had real weight.

Where we would end up would be um the wing flaps being made from uh Theo's um beetle wings processed and cat purring uh very very close mic cating. you get that kind of uh fluttering sound because that mimicked visually what we were seeing. >> This fluttering texture was further enhanced by recording practical organic items struggling against extreme weather condition. The sound teams sought to find a sound that captured the physical strain and rapid unpredictable motion of dragonfly wings in high flight.

By layering these recordings, they could build a believable textured soundsscape that directly influenced how editor Joe Walker cut the film, integrating these bespoke audio patterns into the structure of the scene from the beginning of the editing process, and then uh layered again with the sound of um a canvas strap from a tent um strung in a 140 mph storm so that you'd hear the flapping, the rapid flapping of a very organic piece of material that that you could envision as that maybe that's the sound of a wing.

We would layer those sounds and then um use processing tools to create the Doppler shift for pass and ins and aways and constants while they're in the air. To construct the deep rumbly propulsion of the engines, the sound team avoided synthetic hums and turned to natural animal swarms. They combined these biological flatterings with the mechanical hum of electric car motors, keeping the machinery grounded in recognizable everyday physics.

And then um engine sounds were made almost entirely of bugs, mostly of bees, beehives processed to add some of that flutter to it. The engine is modulating along with the wings. So we would flutter at the same rate that the wings would flutter at. and the mechanics made from mundane things, real things like the mechanics in my Chevy Volt. Just, you know, motors and things that sounded like things you you hear in real life.

This rigorous tactile methodology teaches us that when a sound design choice becomes too exotic, synthetic, or distractingly alien, a director must learn to strip it back. By grounding your world's technology in recognizable realworld acoustics rather than virtual library clicks, you allow the audience to experience genuine familiarity, ensuring that the sound design actively enhances the narrative on the giant screen. >> It came and it came of course it was experimental.

Sometimes they were it was coming and I was I was saying guys it's it sounds great but it's too interesting. It's too too exotic, too. It feels too sci-fi in a way. I when they came back, but what you hear right now, I feel it's grounded. It's the actual real sound of an early doctor. I feel it. >> To design a truly immersive alien world, a film director must learn to embrace the beautiful and unpredictable surprises of natural physics on Earth.

Phil rejects standard digital audio synthesizers, choosing to study how organic environments behave in extreme conditions to create Araus' auditory landscape. His sound department recorded the eerie, surreal singing vibrations of Canadian frozen lakes, grounding the vast sci-fi setting in a highly tactile and natural reality. the sound of a lake, frozen lake in winter in Canada where you have like those eerie, incredible singing sound that I feel absolutely surreal and I wanted to convey that kind of where nature goes in a in a direction with the sound that is absolutely unpredictable that feels very grounded in the reality of the image but feels still as a there's a a connection with the surreal.

Richard King absolutely nailed that. >> This aesthetic dedication to realism completely redefineses the acoustic design of the iconic sandworms. Rather than utilizing standard Hollywood monster tropes or recording real iron roars, Belnou wanted the creatures to feel like natural prehistoric beasts. Their sound must originate from the physical friction of their massive bodies scraping against a rack and rock and deep desert sand mimicking immense ancient sliding structures.

It was important for me that the the worm will not express itself like some kind of ancient dinosaurs or some kind of monster, but that the sound that it will emulate will be inspired by the friction of such a beast in the against the rock and the sand. You will feel almost like it's a bending building against the wind or something. >> VNOV's designers created the physical structures of the sandworm by studying earth biology.

They focused on how its massive mouth functions, detailing the thousands of senue tendrils and throat plates that form its colossal organic throat. The initial sounds that you hear are the actual physical artifacts of its being. The orifice, the maw, if you will. It looks like thousands of senuey tendrils inside the mouth. We created a sound for that. what looks like a throat closing mechanism and you hear the physicality of that. >> To make this massive beast feel like a spiritual entity rather than a simple predator.

Vuv purposely delayed its voice, the audience must wait for hours, feeling the physical presence of the godlike being before hearing its sacred sound. And it isn't until near the very end of the sequence where you actually hear what we would call the voice of the worm. But it's nothing like what you would expect. It's a moment of very simple communication. >> The audience must wait a long time feeling the physical presence of the god-like being before hearing its sacred sound.

This delay constructs immense suspense establishing a direct connection between the sandworm and the fman who worship it. The low deep rhythmic thump generated inside the worm's throat is identical to the thumper devices Fmans deploy in the sand. This reveals that Fman technology was designed over a millennia to directly mimic worm communication building a beautiful cohesive zoological law. >> We also found that there was a connection between the sound that the worm makes with its throat a kind of glunk glunk sound the sound that the FMAN have been using to attract the worm.

So we thought perhaps that suggests that the reason the worms are attracted to that sound is because it sounds like worm communication. >> It's a thumper. Ultimately, this rigorous sound design teaches aspiring filmmakers that the heart of cinema is always organic rhythm. On Arachus, rhythmic sound means certain death. But in the quiet edit room, it is the ultimate creative tool used to drive tension, pacing, and visual storytelling.

The the thing is that at the very center of the of the dune, there's the idea of rhythm. That rhythm that is life, rhythm that is death and and uh uh both gentlemen, if I may, are have musical background. And then the all the movie is constructed about this idea of rhythm. >> In the endless expanse of the Iraq desert, the visual scale shifts inward, transforming from a vast landscape into an intimate psychological chamber.

VNOV explains how physical heat compresses the sonic landscape. >> The silence and the weight of of the heat and brings sound very very close to you. It becomes like a very introspective experience. And the only thing that you can hear sometime is your breathing and and your heartbeat. >> True cinematic tension is never constructed through high volume noise. A master filmmaker utilizes absolute silence to isolate the audience and builds psychological pressure. >> Something about quiet things that I'm terrified terrified by.

There's something about the the absence of sound or just to hear isolate things and to feel the threat coming just from sound. At the beginning, we hear all these voices. This silent isolation dictates the camera's point of view. Following Paul's blindness, we look purely through his limited understanding. This scene will be seen specifically from Paul's perspective and that he has very little information and uh uh uh yeah is trying to decipher and to understand how he would they would be able to survive to the circumstances.

To visualize this blindness, the sound team strips away the standard ambient atmosphere by lowering all background elements. A director can force the audience to focus on tiny isolated sounds before triggering a sudden wave of chaos. And we bring it way down to where you can just barely hear any wind at all and maybe a footstep and then all hell breaks loose. And it's just such a great way to be impactful with the story.

This hyper sensitive world introduces alien sounds that are designed to feel deeply real by altering natural terrestrial elements rather than creating synthetic hums. The director can build a believable organic sci-fi universe that respects our psychological reality. And and I I ask Richard to try to bring alien sounds that feels so close to our own uh uh from that it will not shock our psyche that we will believe that it that can could be a mouse or that could be uh some uh uh insects.

So all those natural sounds that are coming from this desert at night. This sensory design also shapes the subtext of Paul Treati's visions, letting us feel his unsettling ancestral presence on screen. We also develop the voice, the witchy voices come into that and the sort of sense that there's a presence around him. >> To master the art of foley on a budget, you must first learn how to trust acoustic sources over digital ones.

Deny Elnuv believes that starting with real organic recordings is the best way to bypass synthetic cliches, ensuring that your fictional worlds feel subconsciously believable on screen. We can be more successful in our sound design when we start it with acoustic recordings. The reason for that, I think, and this is a hypothesis, I'm not a scientist, is that uh subconsciously there are embedded elements of acoustic recordings that tell the brain this is real.

Instead of using pre-made digital sound libraries, great directors push their crews to record custom elements themselves. This raw approach forces your creative team to interact with their environment and discover completely new sounds daily. And you could just say, "Hey, I need the sound of um a Sardicar guard. I need it sort of like let's get going." And then they would people would record their own things. I mean, I would record my own things. >> By giving your team the creative freedom to explore, you allow them to make mistakes, which believes is the most critical requirement for inventing their original acoustic languages. >> And it's just to have space to explore, to experiment, and to make mistakes, which is crucial to find new ways of doing things. you have to to take risk.

It means that uh the sound that you are hearing in Dune are all the sound to me. Sound that I got used to it rejecting them, bringing them back, modifying, trying things. They have been tested multiple time and and now I'm very comfortable with them and I know they are the right ones. But for that it takes time to experiment. >> If you like this video, subscribe and we'll see you on the next one.
