Making the Sound: Christopher at Sea*

Antfood partnered with one of our favorite collaborators, Tom Brown, to create the sonic world for his animated film, Christopher At Sea, which premiered at Venice Film Festival on September 9, 2022. Alongside composer Brian McOmber, Psyop, and Mr. Bronx, Antfood brought Christopher At Sea to life with poignant, stirring, symbolic, and often unsettling sound design.

The Ask

Christopher At Sea is a 20-minute animated short, described by Brown as “a queer operatic thriller”, following Christopher aboard a cargo ship for a transatlantic voyage. An encounter with a crew hand, Valentin, sets the course for Christopher’s journey of solitude, fantasy, and obsession.

Antfood had previously worked with Tom Brown on teeth (2015) and Cousin John - The Arrival (2020), so the team entered this project with both excitement and anticipation to see what kind of mind-opening, spine-tingling, outside-the-box spectacle Christopher At Sea would be.

Sure enough, Christopher At Sea did not disappoint. In addition to the story’s tense build-up and rich portrayal of Christopher’s perception of the world around him, the film offered a ripe canvas for creative uses of sound. On the first time watching the rough cut with Tom Brown in October of 2021, Antfood’s sound design team identified two major elements to get right in the film’s sound design. First was the recurring sonic motif of the engine room, which Tom referred to as the “beating heart of the ship”, and the second was the finale, which brings the film to a fever pitch.

From start to finish, Antfood produced sound design for Christopher at Sea sound design over the course of 10 months, covering everything from ocean sounds to water drops and damp skin in the locker room. Here are the stories of the creation and production of the engine room rumble and finale sequence.

The Process

Antfood’s sound design team spanned three time zones with Rory White in Lisbon, Bennett Eiferman in Brooklyn, and Zac Greenberg in Los Angeles. The team members deserve major credit for their ability to create and collaborate across such a great geographical distance. And while several conversations took place about the Antfood team doing a transatlantic crossing of our own to work on the sound design together, after seeing Christopher’s fate in the film, they decided against seafaring and took to the skies when schedules allowed in-person collaboration.

The Engine Room

The sound design process for the engine room began with researching the engine sounds of cargo ships as well as trips by our sound designers to sea.

First, Zac did a detailed recording of a friend’s boat in Marina del Ray: “I spent a day…opening up the engine room and mic’ing the dual diesel engines. We put the engine through its paces, idling, revving, trying to coax nuance and diversity from the old engines.”

For further exploration, Bennett took a ride on New York’s Staten Island Ferry to collect a variety of sounds that would be foundational to the film’s sonic environment, and it was there that the engine room sound really started to take shape. “On any boat that is powered by an engine, everything is vibrating, so we had to recreate this omnipresence of a main engine’s drone,” Bennett explains. “Christopher’s building psychosis is narratively tied to his interaction with the ship, so we reinforced that dynamic by accentuating the relationship between his own heartbeat and the ship’s ‘heartbeat’. The ship’s heartbeat was actually derived from an extremely loud and distorted recording of a vent in the stern of the Ferry.”

Bennett and Zac’s field recordings provided the basis for the engine room sound, which was embellished and polished in the studio to make the sound malleable, and applicable for the variety of ways it was used in the film.

The Finale

The sound design for the finale went through many iterations before reaching its final form. With so much happening sonically at this point in the film, the team started by breaking down the scene into specific elements, with Zac and Rory specifically looking at the moments when Christopher was struggling underwater. “Growing up in Colorado,” Zac mentioned, “I spent a lot of time in white water. I used my experiences being swirled around large water to guide my sonic choices.”

Rory, who collaborated with Zac on these moments pulled inspiration from similar memories: “Having spent the last two years totally obsessed with surfing the beach breaks of Lisbon, I channelled the oppression of being held down by a barreling Carcavelos winter wave.”

Despite a focused, iterative creative process, the team struggled to get the finale sequence to perform exactly the way the film needed. “We were banging our heads against a wall with [this scene],” Rory remembers. “Much of the sonic exploration we did before receiving the final animation didn’t make it into our final sound design.”

A noteworthy pizza chef, Rory spent years spinning pies at Brooklyn’s famous Roberta’s Pizzeria. Rory always says that at Roberta’s, the magic really happened when the pressure was on: Friday night dinner rush, seemingly endless orders, pizzas being made left and right. Roberta’s kitchen has become a metaphor here at Antfood, and the pizzas were certainly flying during the final week of work on Christopher At Sea. True to form, during this phase of the project a shift in approach opened up possibilities.

Tides changed when the group had a chance to sit with the final animation – and when the jaws of the final audio deadline were closing. Bennett explains that “a breakthrough occurred when we took a more musical approach to the sonic structure [of the finale],”.

“In the final week of production,” Rory recounts, “we decided to record some wild sounds with a wind ensemble that happened to be in the studio for another project’s recording session. Why not try? We had the players, including Jennifer Fife, Antfood Senior Producer & Program Manager on flute, and Sebastian Sack, one of our summer interns, rising to the occasion on conducting duties.”

Rory elaborates, “It was almost a spur-of-the-moment decision, with a simple score & some spicy playing direction. It ended up sounding pretty odd and helped to elevate the psychedelia in the animation.”

On top of the passages captured from the woodwinds session, the team also layered nearly 30 cello tracks on top of each other to make a really powerful and intense palette as the film builds toward its climax and Christopher’s situation becomes more grave.

Once all of the individual elements were completed, Bennett and Zac spent a week of late nights in our studio in Brooklyn corralling the elements created by the three different creative minds (Rory, Zac, and Bennett) to be the tasteful and dramatic amalgam that drives the culmination of the film.

We worked closely with the talented team at Bronx Audio as we approached the finish line to refine and perfect the sound design. Zac said, “The sonic world we were creating was finding its place all the way up to the final mix session with Dave Wolfe at Mr. Bronx. Dave’s fresh ears and fresh perspective were just what we needed to put the final few pieces into place.”

The Takeaway

We were incredibly fortunate to work with a partner as thoughtful as Tom Brown on this project. Beyond checking our work against the questions,“What would sound good?” or “What would sound realistic?”, Tom encouraged us to zoom out and ask the question,“How does this sound add meaning to the overall story?”.

Thinking critically not only about the sonic aspect of our work but also about the storytelling was an invigorating creative challenge that informed our entire process. Antfood’s own Christopher At Sea journey has encouraged us to bring a story-focused approach to not only sound design but all aspects of our craft–music composition, mix, voice-over, music supervision, sonic branding–for all styles of content, a refreshing reminder to constantly ask ourselves “How does this sound not only work from an aesthetic perspective but also contribute to the overall message, story, or goal of the project?”.
