The official website for the all-new Shirobako movie (Gekijō-ban Shirobako) project began streaming the film's full trailer on Wednesday. The trailer previews the story, in which Marukawa announces that Musashino Animation's original project Time Hippopotamus has been cancelled. However, a project proposal for another original anime film titled Kūchū Kyōshū Yōrikukan Siva (Aerial Assault Landing Ship Siva) arrives at Musashino Animation.
