Oscar-winning director Bong Joon Ho is officially venturing into the world of feature-length animation with his upcoming project, Ally. The acclaimed filmmaker, known for the global phenomenon Parasite, has unveiled a high-profile voice cast for the film, marking a significant milestone in his career as he makes his animated feature debut.
The announcement brings together an eclectic group of talent to lend their voices to the production. The voice cast for Ally includes Alex Jayne Go, Ayo Edebiri, Bradley Cooper, Dave Bautista, Finn Wolfhard, Rachel House, and Werner Herzog. This ensemble marks a bold step for Bong, who is transitioning his signature storytelling style from live-action to the animated medium.
Scheduled for release in 2027, Ally is described as an animated drama that explores the intricate and profound connections between humans and deep-sea creatures. The project has been in development for several years, representing a long-term creative vision for the South Korean director.
A Star-Studded Ensemble for the Deep Sea
The casting of Ally reflects a diverse range of acting styles, blending comedic timing with dramatic weight. The inclusion of Werner Herzog, a filmmaker known for his own distinct cinematic voice, alongside contemporary stars like Ayo Edebiri and Bradley Cooper, suggests a narrative that may balance surrealism with emotional depth.
The announcement of the cast in May 2026 follows a period of intense development, and secrecy. While specific character roles have not yet been detailed, the scale of the voice talent indicates the ambitious scope of the production. The film is being produced by Bong Joon Ho and Seo Woo-sik, the latter of whom previously collaborated with Bong on Mother and Okja.
The project is being produced by Barunson C&C and will be distributed by CJ Entertainment, ensuring the film has the infrastructure and reach of some of the most prominent names in South Korean cinema.
Bong Joon Ho’s Return to Animation
While Ally is Bong Joon Ho’s first animated feature, his interest in the medium is not new. During his university years, Bong experimented with animation through the Yellow Door film club, where he created a stop-motion animated short titled Looking For Paradise. This early experience, as highlighted in the documentary Yellow Door: ’90s Lo-fi Film Club, laid the groundwork for his eventual return to the medium.

The path to Ally has been a meticulous one. Bong began writing the screenplay in 2018, shortly after the completion of Parasite, and finalized the script in early 2021. The creative process was deeply personal; producer Seo Woo-sik noted that Bong often sketched storyboards for the animation process while staying in hotel rooms, illustrating the director’s immersive approach to world-building.
By revisiting animation, Bong is returning to a medium that allows for a level of visual imagination and abstraction that live-action often cannot achieve. This transition allows him to explore the depths of the ocean—both literally and metaphorically—with a level of control and stylized artistry.
The Inspiration: Exploring the Abyss
The thematic core of Ally is rooted in the relationship between humanity and the mysterious inhabitants of the ocean’s depths. Bong has stated that the film is inspired by Claire Nouvian’s novel, The Deep: The Extraordinary Creatures of the Abyss. This influence suggests that the film will lean into the biological wonders and alien-like qualities of deep-sea life to tell its story.
By focusing on deep-sea creatures, Bong is likely continuing his career-long exploration of social hierarchies and the “unseen” elements of existence. The choice of an animated drama suggests that the film will prioritize atmosphere and emotional resonance over traditional animated tropes, aiming for a sophisticated narrative that challenges the viewer’s perception of nature and connection.
The decision to frame the film as a drama rather than a standard family animation indicates that Bong intends to maintain the intellectual rigor and thematic complexity that characterized his previous work.
Production Timeline and Next Steps
The journey of Ally from a 2018 concept to a 2027 release highlights the painstaking nature of high-quality animation. With the screenplay completed in early 2021 and the voice cast now assembled as of May 2026, the production is moving into its critical phases of animation and sound integration.
For those following the progress of the film, the primary checkpoints will be the release of official trailers and further character reveals as the 2027 launch approaches. Given Bong Joon Ho’s history of critical success, Ally is already positioned as one of the most anticipated animated releases of the decade.
The film’s trajectory from a university stop-motion short to a global production involving A-list Hollywood talent underscores Bong’s evolution as a storyteller and his commitment to expanding the boundaries of cinema.
