A German U-boat crew patrols the North Atlantic during World War II. They endure mechanical failure, Allied depth charges and the slow mental wearing-down of men trapped in a steel tube under the sea. It's the definitive submarine film, and few films in cinema keep up claustrophobic dread for this long.
Das Boot is a 1981 war, drama and thriller film directed by Wolfgang Petersen. This breakdown covers 7 techniques (4 cinematography and 3 sound), each with the scene where you can see it. If you like how it is made, Project Hail Mary uses several of the same techniques.
Shrinking the space the characters have as the film goes on, from open places down to cramped hiding spots. The smaller their world gets, the more pressure you feel.
How this film uses it
Petersen's submarine never gets any bigger. As the mission drags on and the damage piles up, the same narrow corridors, the same bunks and the same control room get harder and harder to bear. The camera adds to this by shooting through hatches, over shoulders and between pipes. You never get room to breathe.
Where to see it
The deep-dive sequence. The hull groans under the pressure and the crew is squeezed into corners. The submarine itself becomes the threat.
Inventing a consistent set of sounds for the film, sometimes a whole non-human language. Over time, you learn to read those sounds as clearly as the images.
How this film uses it
Das Boot teaches you to listen. You learn the ping of sonar, the distant thrum of propellers and the particular depth-charge pattern that means an attack is coming. By the film's midpoint, you read these sounds as quickly as the crew does. Sound is now telling the story.
Where to see it
The depth-charge attack sequences. The crew listens to the explosions coming closer. By now, you understand underwater sound and you know which sounds mean death.
Showing heat, sweat and physical discomfort through lighting, costume and acting. The characters' bodies suffer in a way that lets you see their minds breaking down.
How this film uses it
Over the film's runtime, the crew sweats through their uniforms, grows beards and turns pale. Most of the film was shot in story order, so these changes build up on screen. The film puts this physical decline at the center, and it's how you see what is happening to their minds. These are bodies breaking down in conditions that were never meant for people to live in.
Where to see it
The long Atlantic patrol sequences. The crew looks more and more haggard, and their appearance tracks their loss of morale and identity.
Shooting with a handheld camera so the frame shakes and moves with the action. This documentary-style look, called cinema vérité, puts you uncomfortably close to the character.
How this film uses it
During the torpedo attacks and depth-charge sequences, Petersen's handheld camera behaves like another body inside the submarine. It lurches with each impact, squeezes through narrow hatches and chases frantic movement down cramped passages. The rough, documentary-like style lets you feel the crew's panic physically.
Where to see it
The attack on the British convoy. The handheld camera moves through the control room as orders are shouted and the submarine maneuvers.
Removing music, background sound or dialogue from a moment where most films would fill it. The quiet forces you to sit with what is on screen.
How this film uses it
In the silent-running sequences, the crew must stay completely still to avoid being detected. Petersen removes all sound except breathing. There is nothing peaceful about the silence. It is the concentrated dread of men who know any noise will kill them. The absence of sound becomes the most threatening thing in the film.
Where to see it
The silent-running sequences after depth-charge attacks. The crew is frozen and the submarine drifts. Silence is how they measure survival.
Shooting almost the whole film in 1 confined place. Set design and camera movement keep it visually interesting, and the space itself takes on meaning as the story goes on.
How this film uses it
The U-96 is the film's main world. Petersen shoots it with lenses that stress the tunnel-like corridors, the inches between bunks and how close the men are to each other with no escape. The physical reality of the submarine drives the drama. Space itself is the enemy.
Where to see it
The crew running from bow to stern to adjust trim, the balance of the boat. You travel the full length of the submarine, and you learn its layout through urgent motion.
Mixing battle sound the way a soldier would hear it, with chaotic, physical noise coming from every direction. Nothing is tidied up for your comfort, so you feel inside the fight.
How this film uses it
In the depth charge sequences you hear the distant boom, the delay, then the blast that shakes the hull. The sound tracks the explosions getting closer. Your body reacts to the sound before your mind can work out what is happening.
Where to see it
The first depth charge attack. The crew is still and silent. The sound arrives from far away and then shatters up close, and the hull groans under the pressure.
