Bradley Cooper has joined the English voice cast of Ally, the first feature-length animated film from director Bong Joon Ho. The casting update places Cooper among a growing international voice lineup for the film, which is being developed with a target of completing production in the first half of 2027.1
The Bong Joon Ho Ally project is drawing attention not only because of Cooper’s involvement, but also because it marks a new format for the director after a career associated with live-action cinema. The film centers on Ally, a baby pig squid, and an adventure that moves from the deep sea toward the world above the surface after an unidentified aircraft crash.1
Bradley Cooper Added to Ally English Voice Lineup

SBS News reported on May 12, 2026, that Bradley Cooper will participate in English voice acting for Ally. The same report named Dave Bautista, Ayo Edebiri, Werner Herzog, Rachel House, Finn Wolfhard and Alex Jayne Go as part of the voice cast.1
Yonhap News Agency also reported that Cooper, Ayo Edebiri and Dave Bautista are participating in the English dubbing, citing Deadline and CJ ENM. Yonhap additionally listed Werner Herzog, Rachel House, Finn Wolfhard and Alex Jayne Go among the cast members, while noting that Korean dubbing casting will be decided later.2
Cineplay described the announcement as the unveiling of an English dubbing lineup that includes Cooper. It also noted that Cooper and Bautista, both associated with Guardians of the Galaxy, are now listed together as voice cast members in Bong’s animated film.3
The available reports do not specify which characters the actors will voice. They also do not provide a completed Korean-language cast list, a confirmed release date by territory, or ticketing information. At this stage, the confirmed focus is the English voice lineup and the film’s production and distribution framework.
What Is Known About Bong Joon Ho’s Ally
Ally is described as Bong Joon Ho’s first feature-length animated film. CJ ENM announced through its official newsroom on April 3, 2026, that production had been confirmed and that the project was aiming for completion in the first half of 2027.4
CJ ENM’s announcement said the work is inspired by real marine life and deals with themes of friendship and courage. The company also said Barunson C&C is overseeing production, with production staff from 12 countries including Korea and global studios including DNEG taking part.4
Cineuropa reported that the film follows Ally, a baby pig squid living in the deep sea of the South Pacific, who dreams of seeing the sun and becoming the subject of a wildlife documentary.5 SBS News summarized the story as an adventure involving the baby pig squid and friends heading toward the world above the surface after an unidentified aircraft crash.1
The screenplay information also places Ally within a longer development timeline. Variety reported on April 29, 2026, that Bong co-wrote the script with Jason Yu and that the project had been in development since 2019.6
Distribution and Production Framework
Neon has secured North American distribution rights to Ally, reuniting Bong with the distributor associated with Parasite in North America. Variety reported that Neon had taken North American rights and that Ally is targeting a 2027 theatrical release.6
Yonhap News Agency also reported that Neon will handle North American distribution. The same report said Korean dubbing casting would be determined at a later stage, leaving the current casting news centered on the English-language voice version.2
CJ ENM, Penture Invest and Pathé are listed as companies handling financing and distribution. Variety reported that Ally is aiming for a 2027 theatrical release, while CJ ENM’s official newsroom identified the first half of 2027 as the target for completing production.64
Cineplay also reported that CJ ENM, Penture Invest and Pathé Film are involved in investment and distribution, with Barunson C&C overseeing production.3 That structure places the film across Korean, European and international production and distribution channels, although the sources provided do not specify final release dates for individual markets.

The latest confirmed development is Cooper’s addition to the English voice cast alongside Bautista, Edebiri and other named performers. With production still targeted for completion in the first half of 2027, Ally remains a film in development, and the next major updates are likely to concern character assignments, Korean dubbing, and territory-specific release plans as they are officially announced.
