Shirobako: The Movie (Japanese: 劇場版 SHIROBAKO, Hepburn: Gekijōban Shirobako) is a 2020 Japanese animated film and a sequel to the anime television series Shirobako (2014–2015). Produced by P.A. Works and Infinite and distributed by Showgate, the film is directed by Tsutomu Mizushima from a series composition led by Michiko Yokote and features an ensemble cast including Juri Kimura, Haruka Yoshimura, Haruka Chisuga, Asami Takano, and Hitomi Ōwada. Set four years after the events of the anime series, the film follows Aoi Miyamori leading an anime film project at Musashino Animation.

Talks for a sequel to the anime series began in 2016. The sequel, which was revealed to be an anime film, was announced in April 2018, along with the confirmed return of Mizushima and Yokote. The staff from the anime series were confirmed to be returning for the film in July 2019. The returning cast from the anime series were also confirmed that month and in January 2020. The film was completed three days before its theatrical release.

Shirobako: The Movie was released in Japan on February 29, 2020. The film grossed over $3 million worldwide and received a nomination at the Crunchyroll Anime Awards.

Time Hippopotamus, Musashino Animation's original anime series, gets canceled after its sponsor could no longer finance it. As a result, some of the staff leave the studio and Masato Marukawa resigns as its president. In April 2019, Aoi Miyamori and the remaining staff watch an episode of Third Aerial Girls Squad Medusa☆, an ecchi sequel to Third Aerial Girls Squad animated by Studio Taitanic Film. Shun Watanabe, the new president of Musashino, discusses with Miyamori the possibility of her producing Air Amphibious Assault Ship SIVA, an original feature-length anime film set to be released in February 2020. Gōtarō Katsuragi pleads to Miyamori to finish the film after GPU, the studio attached to it, failed to complete its storyboards while also demanding a bigger budget. With motivation from Marukawa, Miyamori accepts the job. She then meets Kaede Miyai, an assistant producer and Katsuragi's colleague at Western Entertainment who will be working with her on the film.

As the production starts nine months before the film's release, Miyamori suggests using the materials from Time Hippopotamus. She then convinces Seiichi Kinoshita to direct the film. Afterward, the two meet with Shimeji Maitake, who agrees to write the film's script. Miyamori invites Yumi Iguchi, who only offers to help with the character design, and recruits Rinko Osagawara. Misato Segawa and Yūichiro Shimoyanagi attempt to recruit Ryōsuke Endō, the one who has been affected by the cancellation of Time Hippopotamus the most. With motivation from his wife Mayumi, Ryōsuke finally decides to join the staff. Miyamori recruits Ema Yasuhara, while Shizuka Sasaki plans to audition for a role in the film and Misa Tōdō accepts the position as the film's chief animator. Miyamori asks Shigeru Sugie to help with an animal drawing in exchange for her accepting his favor to help with his animation class for children.

With six months left until the premiere, Maitake is not feeling satisfied with his script but after hearing Sasaki's audition and getting ideas from Midori Imai, he manages to complete it. Meanwhile, Masashi Yamada has been falsely accused of controversy and Yasuhara is encountering a problem with her corrected keyframes. Tarō Takanashi and Daisuke Hiroaka offer help with the film despite them now working in another studio. Two months later, Erika Yano returns to Musashino, helping with Kinoshita's storyboarding and recruiting Hiroshi Iketani. Miyamori, Yasuhara, Sakaki, Tōdō, and Imai participate in Sugie's animation class, during which they also garner experience and motivation. Sometime later, Sasaki passes the audition for the role of Arte in the film and Yasuhara finally submits well-corrected keyframes.

Katsuragi later informs Miyamori, Miyai, and Watanabe about GPU President Yoshio Misaki's claim that his studio has also the rights to the film. They fear that GPU might halt the production or wants to have a joint production as the lead. Miyamori and Miyai storm Misaki's office and inform him that he violated sections of the contract. With three weeks remaining until the premiere, the film has been completed, but Kinoshita feels the ending is rushed. Miyamori requests the production team to remake the final part to make the film satisfactory for themselves and the filmgoers. On the film's premiere, Miyamori, Yasuhara, Sakaki, Tōdō, and Imai visit a theater to watch the finished product.

Initial talks for a sequel to the anime television series Shirobako (2014–2015) began a year after the end of its broadcast. During the P.A. Works panel at the Tokyo Anime Award Festival in March 2016, Shirobako producer Takayuki Nagatani teased that "there might be a chance [for a sequel]" to the anime series if a theme could be decided. P.A. Works CEO Kenji Horikawa would like "to see a story about Aoi [Miyamori] going back to her hometown and teaching an anime class for children" in the sequel. The staff "could always make a sequel if [they] wanted to" since they could use their daily lives during the production of an anime as the story, but it took a few years for them to ask the anime series director Tsutomu Mizushima to helm the sequel due to his "far in advance" schedule.
