How five films turned sound into a storytelling revolution

Picture this: you walk into a packed cinema in Melbourne's CBD on a Friday night. The lights drop, the trailers finish, and within seconds your body reacts before your eyes catch up. A deep rumble in your chest, a whisper that makes the woman next to you lean closer, a sudden silence that pulls the air from the room. Most people call this atmosphere, but a few stubborn artists call it the whole point.

Sound design rarely wins the headlines. Visual effects get the magazine covers, the behind-the-scenes reels, the documentary treatments. Yet every seasoned viewer across the country knows that the films which haunt them long after the credits roll almost always got there through the ears first. The right sonic choice can turn a forgettable story into something lodged permanently in the nervous system.

Australia, oddly, has a rich relationship with bold sound work. From the early days of Madman Entertainment championing foreign-language oddities on DVD to ACMI's ongoing exhibitions exploring how filmmakers shape aural worlds, local audiences have always gravitated toward movies that treat sound as a character rather than decoration. Even now, while streaming platforms flood Australian screens with algorithm-flattened content, dedicated cinephiles are heading back to physical media, hunting down discs that preserve these cinematic experiences the way their creators intended.

What follows is a look at five films that pushed sound into territory nobody had charted before. Some are obvious choices, others might surprise you. All of them reward a good pair of headphones, a darkened room, and the kind of patient attention that a film buff can only really give when the phone is in another room and the kettle has been put on for a long arvo's viewing.

The unheard story of cinema's most underrated element

For the first forty years of feature filmmaking, sound was treated like plumbing. Studios wanted it functional, invisible, and identical from one movie to the next. Then a handful of directors and sound editors began asking what would happen if the audio was allowed to lead the story instead of merely support the pictures. The answers changed movies permanently.

The transition was never sudden. It happened in workshops, in test screenings, in long arguments between composers and directors about whether a scene needed music or only the hum of a city. It happened through new gear like portable mixers, contact microphones, and early digital samplers that let editors sculpt sound the way a sculptor works clay. It happened because a few filmmakers realised that audiences feel a movie before they understand it, and feeling lives in the ear.

In Australia, this shift is easier to appreciate now than ever. The country has a proud tradition of independent cinemas in suburbs like Carlton and Newtown, where repertory screenings are programmed by humans rather than suggested by algorithms. Many of these venues have kept their projection booths alive by hosting dedicated soundtrack events and score-listening sessions. Anyone who once had to hunt for imported discs at JB Hi-Fi now trades recommendations online, comparing notes on which pressings preserve the original theatrical mix.

Eraserhead and the birth of industrial sound

David Lynch's debut feature is famously difficult to describe. Its images are unforgettable: the spindly-haired Henry Spencer, the grotesque baby, the bleak industrial wasteland that looks like a coal-streaked suburb of another planet. Yet what really lodges in the mind is the sound. Hisses, rumbles, distant thuds, and a sustained drone of mechanical dread fill every frame.

Lynch and sound designer Alan Splet built the audio from the ground up, recording industrial noise from factories around Los Angeles and layering it with dissonant organ and ambient hum. The film never tells you where you are, but your ears know it is somewhere hostile, somewhere humid and metallic and slightly alive. For many viewers, this was the first time a movie had used sound to create an entire world, rather than to illustrate the pictures.

Australian fans of the strange and surreal have long embraced Lynch. Madman Entertainment released several of his titles locally, and his work still sells briskly to collectors hunting down definitive editions. Disc buyers in Adelaide and Hobart often list Eraserhead among the films they refuse to watch on streaming because the compressed audio robs the film of the very thing that makes it work.

The Conversation makes listening the whole point

Francis Ford Coppola's 1974 thriller stars Gene Hackman as Harry Caul, a surveillance expert obsessed with capturing a conversation between two lovers in a crowded public square. The entire plot turns on audio: a single mumbled word, a background noise, the rustle of clothing. Coppola and sound editor Walter Murch turned the mixing console into a weapon.

Murch, who would later help redefine sound editing on Apocalypse Now, used the film to explore what would happen if the audience heard exactly what the protagonist heard. Distant chatter becomes deafeningly loud. Footsteps swell. Background noise warps and pulses, mimicking the anxiety of a man whose livelihood depends on catching a syllable. The technique was so precise that audiences in the early screenings reported feeling physically unwell during the climax, a ringing silence as Caul tears his apartment apart looking for hidden microphones.

The Conversation is the kind of film Australian cinephiles love to discover through physical media. Its Blu-ray releases preserve the careful stereo imaging in ways that flat television speakers flatten beyond recognition. Browsing through a well-stocked rental wall, the kind you can still find in independent stores across Melbourne's inner north, often turns up forgotten gems like this one, sitting beside bigger titles but quietly waiting for someone willing to listen.

2001 rewrites what silence can do

Stanley Kubrick's space epic is famous for many things: the stargate sequence, the rogue computer, the dawn-of-man sequence with its match-cut bone-to-satellite transition. Among sound designers, it is famous for something else entirely. Kubrick and his team decided that space should not have a soundtrack, even though everyone assumed it would.

When astronaut Dave Bowman floats outside the ship to retrieve the lost camera, the film gives you the eerie quiet of a vacuum. No explosions, no engine roar, no swooshing spaceships. The result is profoundly unsettling, because it tells the audience, on a gut level, that the human body is the only source of warmth in the universe. Combined with the deliberate use of Richard Strauss and Johann Strauss on the soundtrack, 2001 made silence feel as orchestrated as any symphony.

The film was released just as Dolby was being introduced to commercial cinemas, and Kubrick insisted on a custom sound mix that pushed the new technology hard. Australian audiences at the time queued around the block for roadshow screenings, paying premium prices to experience the film as its maker intended. For anyone revisiting the film today, the lesson is the same: find the best speaker setup you can, because every silence and every Strauss waltz has been placed with surgical intent. Cinephiles who enjoy this kind of granular attention to craft will appreciate the art of the animated short film on dvd, which takes a similarly obsessive approach to a different corner of cinema.

Apocalypse Now opens the era of loud cinema

Coppola's Vietnam War odyssey was one of the first films mixed in 70mm Dolby stereo, and it uses every channel with operatic confidence. The helicopter attack that opens the film is a masterclass in immersive sound: rotors above, machine guns erupting from the surrounds, Wagner blasting from somewhere you cannot place. By the time the sequence ends, you have been sonically relocated to a country half a world away.

Walter Murch, who edited both The Conversation and Apocalypse Now in close succession, treated the audio as an additional camera. He could cut between perspectives through sound alone, switching from a Saigon bar to a jungle river without a visual transition. The film is famous for its quotable lines, but its sonic architecture is what holds the whole sprawling enterprise together.

For Australian audiences, Apocalypse Now has a curious local afterlife. It was one of the first major studio films to be released here on laserdisc, and those discs remain prized possessions among older collectors. Today, anyone walking into a Palace Cinema in Sydney or Melbourne for a restored screening understands instantly what the fuss was about. The film practically demands a darkened room and an audience willing to be overwhelmed, a perfect match for the communal experience that streaming can never quite replicate.

Dunkirk proves restraint is a sound designer's best tool

Christopher Nolan's 2017 war film is the most modern entry on this list, and arguably the most radical. Where Apocalypse Now uses sound as a weapon, Dunkirk uses it as a clock. Working with sound editor Gary Rydstrom, Nolan built the entire tension of the film around a Shepard tone, an audio illusion that sounds like it is constantly rising in pitch but never actually arrives anywhere.

Layered over the ticking of a pocket watch, the crash of waves, and the sudden silences between explosions, the Shepard tone creates a physiological sense of urgency that has nothing to do with the visuals. Audiences emerged from cinemas reporting that their heart rates had genuinely risen during the runtime. It was, as several Australian reviewers noted at the time, less a movie than a fair dinkum controlled experiment in how audio can manipulate the body's response to images.

For anyone inspired to dig deeper into how filmmakers treat sound as a serious craft, the team behind Rain City Video has put together a useful hub at their links page, where you can find other resources for serious movie watchers. The lesson all five of these films teach is the same: a soundtrack this careful wants the room to itself, and the rest of the world can wait.
