The Musashi-Sakai x Shirobako Harumatsuri (Musashi-Sakai x Shirobako Spring Festival) event in Tokyo for the Shirobako anime revealed on Saturday that the franchise will get an anime film project. P.A. Works is starting production on the film, but the film does not have a set release date yet. The staff at the event confirmed that the film will be an all-new work.
Because it is populated by TOP 10 ranking since 2020, it is still a work in progress. Multiple links in the same country lead to different streaming versions.
