The Plot of Night’s End

Night’s End follows the story of an anxious shut-in who moves into a haunted apartment and hires a stranger to perform an exorcism. However, things quickly take a horrific turn, leading to a chilling and terrifying ordeal. The film stars Geno Walker, Kate Arington, Michael Shannon, Isaac Dees, Felonious Munk, Daniel Kyri, and Theo Germaine.

What Attracted Cooper to the Night’s End Script?

Cooper reveals that he was drawn to the character of Ken, the lead, who embodies solitude and isolation. As the world had just experienced the COVID-19 pandemic, this resonated strongly with Cooper and many others who had grown accustomed to increased remote interactions through phones and computers. The prospect of providing a musical accompaniment to Ken’s lonely apartment setting, with slow and subtly evolving chords, textures, and colors, intrigued Cooper.

The Role of Script Reading in Cooper’s Creative Process

Cooper explains that when initially reading a script, he deliberately avoids thinking about the music. It is only after allowing the story to settle in his mind that he begins to contemplate the desired mood or theme. Taking note of generalized musical ideas, he ensures he verbalizes his intentions before diving into the composition process. By doing so, he captures his initial instincts and prevents losing track of the original vision.

Initial Discussions and Creative Direction for the Film Score

Cooper engaged in early discussions with director Jennifer Reeder soon after reading the script. Knowing he wanted to incorporate a synth-heavy sound with orchestral elements, Cooper aimed for a hybrid composition. He communicates his themes best through synthesizers, but by adding strings and other orchestral instruments, he could explore conventional dissonance and discomfort, which are crucial in creating the desired horror film atmosphere. Reeder, familiar with Cooper’s style, gave him the creative freedom to experiment and explore his musical ideas.

Finding Inspiration Without Watching Other Horror Films

Interestingly, Cooper decided not to watch other horror movies during most of the scoring process. His aim was to avoid sounding derivative and instead leave a unique musical imprint on Night’s End. While he acknowledges the presence of his influences, he wanted to compose in his own distinctive style, pushing the boundaries of dissonance while maintaining a careful balance. Toward the end of the film, he did draw inspiration from the haunting scores of Disasterpeace’s “It Follows” and Colin Stetson’s “Hereditary.”

Story Elements and Musical Reflections

Cooper identifies the theme of isolation as a significant element that influenced the musical tone throughout Night’s End. As the events in the film progress from bad to worse, the discomfort experienced by the characters becomes increasingly palpable through the music. Cooper also credits director Reeder’s deliberate pacing and the outstanding cinematography by Christopher Rejano for shaping the mood of the film and guiding his musical choices. The overall sadness and melancholic nature of the story aligned with Cooper’s musical sensibilities, creating a seamless fusion between the visuals and the score.

Character Themes and Musical Representation

One notable aspect of the score is the specific theme created for Ken’s morning routine, which intensifies as the film unfolds. Cooper took care to degrade the harmony of this theme gradually to mirror Ken’s deteriorating mental state. Through repetitive, slightly dissonant arpeggios layered over a simple chord progression, the music symbolizes the character’s descent into madness.

The Influence of the Setting on the Score

Given that the majority of Night’s End takes place in Ken’s apartment, the setting played a crucial role in Cooper’s work. By employing slight variations on repeated musical themes, he accentuated the different scenes within the apartment. The use of altered melodic and harmonic ideas provided continuity and cohesion, allowing the score to tie various moments together.

Cooper’s Journey into Film Composition

Cooper’s involvement in film composition began when director Jennifer Reeder approached him after witnessing his band’s performance. Intrigued by the possibility, he collaborated with Reeder on one of her early short films and discovered a natural synergy between their styles. Since then, he has continued to compose for Reeder as well as other directors and artists, further fueling his love for the craft.

Influential Horror Film Scores of the Past Year

One horror film score that captivated Cooper in the past year was Ben Lovett’s work on “The Night House.” As the story unfolds, Lovett’s score masterfully transforms moments of terror into a sad and relatable tragedy. The music seamlessly transitions between beautiful and atonal compositions, perfectly complementing the film’s disturbing themes and leaving a lasting impact on Cooper.


With Night’s End, composer Casey J. Cooper (CoastalDives) has once again demonstrated his exceptional talent in crafting atmospheric and evocative scores. His ability to capture the emotions and intricacies of the film’s narrative through music is commendable. As viewers embark on a journey into the haunted apartment alongside the characters, Cooper’s score enhances the tension, isolation, and looming dread, making Night’s End an unforgettable cinematic experience.
