Produced by Sedic International and distributed by Toho, the film was directed by Shinsuke Sato from a script written by Akiko Nogi.

It stars Junichi Okada as Atsushi Dojo and Nana Eikura as Iku Kasahara, alongside Kei Tanaka, Sota Fukushi, Naomi Nishida, Jun Hashimoto, Kazuma Suzuki, Kazuyuki Aijima, Kyusaku Shimada, Kiyoshi Kodama, Chiaki Kuriyama, and Kōji Ishizaka.

Filming began in September 2012 and concluded in December of that year, taking place at Saitama, Ibaraki, Yamanashi, and Fukuoka prefectures.

This incident inspires Kasahara to join the Library Defense Force in 2019 to find her so-called "prince", where she is placed under the supervision of instructor Atsushi Dojo, whom she has trouble getting along.

Later, she and Hikaru Tezuka are transferred to the elite unit Library Task Force led by its squad leader Ryusuke Genda.

While fighting is taking place outside, library staffer and Kasahara's friend Asako Shibasaki finds two Media Betterment agents entering the premise.

A live-action film adaptation of the light novel series Library War by Hiro Arikawa was announced in August 2012, with Shinsuke Sato serving as the director.

[7] The gunfight scene that was filmed in a shopping center at Jōsō, Ibaraki had more than 5,000 gunshots fired, in addition to 40,000 magazines and books scattered all over the floor.

[8] In November 2012, Chiaki Kuriyama, Kōji Ishizaka, Kei Tanaka, Jun Hashimoto, Naomi Nishida, and Sota Fukushi joined the cast.

[11] In February 2013, Jōji Abe, a Japanese actor and member of the theater troupes Caramel Box and Sky Rocket, was confirmed to be making an appearance.

[29][30] Mark Adams of Screen Daily stated that Library Wars was a "sci-fi film that makes the most of the most incongruous of action concepts."

[18] Andrew Mack of Screen Anarchy felt the film was "thoroughly entertaining and funny" and praised its action sequences and romance plot.

[31] Clarence Tsui of The Hollywood Reporter felt the film was "more like an inflated tele-serial skipping from one thread to another, sometimes with its dystopian settings largely forgotten as the main protagonists' light-as-air emotional struggles taking over."

Tsui noted that the raison d'être for Japan's tolerance on Library Defense Force despite being an authoritarian state was never made clear.

Additionally, Okada and Eikura were set to reprise their roles, alongside the returning cast members Tanaka, Fukushi, Kuriyama, Ishizaka, Nishida, and Hashimoto.
