, also known as Digimon Adventure: Children's War Game!, is a 2000 Japanese anime short film directed by Mamoru Hosoda and produced by Toei Animation. A part of the Digimon media franchise, Our War Game is a sequel to the 1999 anime television series Digimon Adventure and is the second Digimon film overall. The film premiered in Japan on March 4, 2000 as part of the Toei Anime Fair (being screened alongside One Piece: The Movie); in North America, portions of Our War Game were included in the 2000 film Digimon: The Movie. Hosoda has cited Our War Game! as a major influence on his 2009 film Summer Wars, with critics noting numerous similarities between the films. The events of the film take place during the first season of Digimon Adventure.
Plot
Following the return of the DigiDestined from the Digital World, Izzy discovers a corrupted Digimon on the Internet that grows by consuming data. He rushes over to Tai's apartment, where they observe its consumption disrupt computer systems across Japan. Taichi / Tai and Koshiro are contacted by their Digimon partners Agumon and Tentomon from the Digital World; they battle the corrupted Digimon, but are defeated.
With the national PSTN crashed, Tai and Izzy attempt to contact the other DigiDestined by an emergency voicemail system, but most of the DigiDestined are unavailable. Fortunately, they are able to contact Matt and T.K., who are visiting their grandmother in rural Shimane. Yamato / Matt and Takeru / T.K.'s Digimon partners Gabumon and Patamon join the fight, but are physically slowed as a result of thousands of e-mails being sent to Taichi and Koshiro by other children observing the battle on their computers around the world.
The enemy Digimon, having evolved into Diablomon, creates thousands of duplicates of itself and hacks The Pentagon to launch an LGM-118 Peacekeeper missile at Tokyo. Taichi and Yamato magically enter their computers, and rally their Digimon to jointly evolve into Omegamon and defeat the duplicates. Koshiro forwards the thousands of emails to the original Diablomon, slowing him enough to be defeated. With Diablomon vanquished, the disarmed missile crashes harmlessly into Tokyo Bay.
Cast
Production
Our War Game was directed by Mamoru Hosoda, written by Reiko Yoshida, and produced by Toei Animation. It is the second of two Digimon movies directed by Hosoda, following 1999's Digimon Adventure. Hosoda was given both Digimon films to direct by the company after he expressed a desire to make movies. Hosoda pitched two plots for the film: a road movie inspired by Midnight Run in which Kamiya and an original character travel to Okinawa, and a WarGames-inspired film in which the protagonist saves the world without leaving their home. Toei selected the latter concept. In early drafts of the script, Our War Game focused on a plot where the Year 2000 problem was caused by a Digimon. Hosoda stated that he wished to use the film to make the problem more understandable for children, but later abandoned the concept, believing the film would become dated after the year 2000 had passed; references to the Year 2000 problem nonetheless appear in some promotional materials for the film.
Constrained by the 40 minute runtime of Our War Game and seeking to make a film less serious than Digimon Adventure, Hosoda created Our War Game as a "childish, simple story where you just have to enjoy the thrill." Noting that he "couldn't make a great emotional story" in 40 minutes, he narrowed the focus of the film from the television anime series' ensemble cast of eight characters and their Digimon partners to just four core characters Kamiya, Ishida, Izumi, and Takaishi. Inspired by the 1994 film Speed, he structured the film around a countdown to add suspense, with the events of the film occurring approximately in real time.
The film's soundtrack is composed by Takanori Arisawa, who composed the soundtrack for the Digimon television anime series. Maurice Ravel's Boléro and "When Johnny Comes Marching Home" are used as motifs, the latter of which was included by Hosoda as a reference to its use in the bomb run scene in Dr. Strangelove. The insert song "Requiem", which is sung during the climax by The Little Singers of Tokyo, is a revision of "Pie Jesu", a traditional Catholic hymn. "Butter-Fly" by Kōji Wada is used as the film's opening theme song, while "Sakuhin No. 2 "Haru" I Chōchō ~ Bokura no War Game!" by AiM is used as the ending theme. The film's soundtrack is included on the album Digimon Adventure 02 Uta to Ongaku Shū Ver.1.
