In Kathryn Bigelow’s “A House of Dynamite,” the intense suspense is amplified by Volker Bertelmann’s masterful score. As a missile hurtles toward the United States, the film is an edge-of-your-seat thriller driven by the combined efforts of a talented team, including Bertelmann, editor Kirk Baxter, and sound designer Paul Ottosson. Together, they craft an atmosphere brimming with tension and anxiety, underscoring the urgency of the narrative.
The Power of Music in Building Suspense
The film, now available on Netflix, is segmented into three chapters, each offering a different viewpoint. It kicks off in the White House’s Crisis Room, where Captain Olivia Walker, portrayed by Rebecca Ferguson, collaborates with Major Daniel Gonzalez, played by Anthony Ramos, at a military base in Alaska. With only 20 minutes to respond to an incoming missile, the pressure is palpable.
Composer Volker Bertelmann played a crucial role in elevating this tension. As Ottosson noted, reading the script alone was an anxiety-inducing experience. Bertelmann aimed to enhance this effect through his score, which opens with a palette of sounds that immediately tells the audience they are in a gripping thriller. His careful manipulation of music guides viewers through the peaks and valleys of suspense, ensuring the tension remains taut throughout.
Crafting the Film’s Tense Atmosphere
Editor Kirk Baxter used Bertelmann’s score as a key element in shaping the film’s rhythm. He explains that the music reaches a crescendo at the end of Chapter One, triggering a reset that keeps viewers guessing. The sprinkling of audio cues, he adds, sustains the anxiety, leaving audiences in a perpetual state of alertness.
Each chapter’s sound design was meticulously crafted by Ottosson. During the first two chapters, confidence reigns, with characters reacting based on their training. However, as events unfold, chaos creeps in, reflecting the unpredictable environment they face. By the third chapter, when the focus shifts back to the Oval Office, we meet Idris Elba’s character, previously only a voice, which adds a human element to the swirling uncertainty.
Humanizing the Crisis
Baxter highlights the strategic decision to save Elba’s reveal for later in the film. This choice heightens anticipation and reinforces the personal dimension of the crisis. In the third chapter, the emphasis is placed on the President’s experience, underscored by moments of silence alongside Bertelmann’s evocative music. This focus on humanity amidst chaos brings an emotional depth to the narrative.
The story culminates in a deeply personal portrayal of the President as the conflict reaches its resolution. Against the backdrop of global tension, Baxter incorporates a moment where the President relives a conversation with Russia. Though initially deemed unnecessary, the interaction adds layers to the character’s journey, mirroring the emotional stakes portrayed through Bertelmann’s relentless score.
Adding Realism through Expert Consultation
To ensure authenticity, sound designer Ottosson worked closely with military advisor Dan Karbler, whose insights were invaluable. This collaboration aimed to replicate the genuine sounds and feelings within such high-stakes scenarios, further enhancing the film’s realism. Ottosson emphasized the importance of capturing not just the sound, but the atmosphere and emotions of such a critical situation.
“A House of Dynamite” owes much of its heart-pounding tension to the synergy between its score, editing, and sound design. Volker Bertelmann’s contribution stands out as a pivotal element in creating a film that is as emotionally compelling as it is thrilling.
