Director and screenwriter Hitoshi Ōne initially turned down the offer to adapt Bakuman to live-action film. He felt that the meta-aspect of a Weekly Shōnen Jump manga about Weekly Shōnen Jump manga would be lost in another medium. But after re-reading the series, he realized it is a coming-of-age story at heart and changed his mind. He also liked how there were many homages to Fujiko A. Fujio's Manga Michi, a personal favorite of his.^[2] Ōne wanted Bakuman to be a story about "friendship, effort, and victory", the motto of Weekly Shōnen Jump, and a buddy story between two men, but to also have a team feel.^[3] While writing the screenplay, he interviewed the Weekly Shōnen Jump editorial department and many manga artists, including Takeshi Obata, illustrator of the original Bakuman manga. Obata drew some of the manga manuscripts seen in the film, as well as the images that appear on the blackboard in the final scene.^[2] The Weekly Shōnen Jump editorial office seen in the film is a faithful recreation of the magazine's actual editorial office.^[4]

Ōne said that while writing the script was difficult, having done over 20 drafts, preparing for and casting the film went smoothly.^[2][3] When the cast was revealed, many people felt that Takeru Satoh and Ryūnosuke Kamiki should have been cast in each other's role. The actors themselves were also initially surprised when they were first given their roles. But Ōne decided from the beginning that "manga otaku" Kamiki was more likely to think up a manga story, while the stoic Satoh would be able to show his heart honestly, and the actors eventually felt it was the right decision as well. Wanting someone who could draw for the part of Taro Kawaguchi, Ōne saw Kankurō Kudō portray Shigeru Mizuki in GeGeGe no Nyōbō and knew he could pull it off.^[3] Ōne said of all the manga adaptations he has made, Eiji Nizuma might have been the most difficult character to portray. Due to the time restraint, Nizuma is more of a rival to Mashiro and Takagi in the film, compared to the manga where he becomes their friend too. Akira Hattori also differs from his manga counterpart, with Ōne describing him as a mix of the original character and Monji, the real-life second editor of the Bakuman manga.^[2]

Satoh practiced using a G-pen nib about two months before shooting began. The film has an action scene where Mashiro and Takagi "battle" Nizuma with large pens and pencils as swords. Satoh and Kamiki said their experience working opposite one another on Rurouni Kenshin: Kyoto Inferno and Rurouni Kenshin: The Legend Ends made it so that they were comfortable with each other in the fight scene. Satoh and Kamiki ad libbed some of the parts in the film, such as the lines their characters make discussing what kind of manga they want to create when they initially team up, and Takagi's reference to Kyūkyoku!! Hentai Kamen.^[3] The scene where the manga artists gather after the award ceremony is an homage to a similar scene in Tokiwa-sō no Seishun, a 1996 film about Tokiwa-sō.^[2]

The soundtrack was written and performed by Japanese band Sakanaction, including the theme song "Shin Takarajima", which they released as a single four days before the film's release.^[5] Ōne decides who he wants to provide the music to his films before he starts writing the script or thinking about the cast.^[4] He feels that professional film composers are not suitable for his work, and prefers to hire actual artists for the job. Sakanaction were one of many acts he considered, saying he wanted to take advantage of their popularity. It was after seeing them perform live in 2012 that Ōne decided to choose them for Bakuman. Aware of Ōne's reputation and work, being a particularly big fan of the Yura Yura Teikoku concert film Yura Yura Teikoku Live 2005-2009, Sakanaction frontman Ichiro Yamaguchi said he felt that he and the director were both cut from the same cloth and was excited to work with him. After reading the script, Yamaguchi made and sent about 10 demos to Ōne. The demos were then put to footage from the film and they discussed in detail changes to the music based on each scene. Unlike most films where the music is made to match the edited footage, Ōne prefers to edit his films to the music. Yamaguchi said that Sakanaction had self-produced their music up to that point, so it was a new experience for them, as if they were working with a record producer.^[4]

The film was released in Japanese theaters on October 3, 2015 by Toho. It was featured at the 2015 Japanese Film Festival in Sydney and Melbourne, Australia.^[6]

Matt Schley of Otaku USA wrote that Bakuman. is "a real celebration of and testament to the unique power of Japan's comics culture" and the best live-action manga adaptation he's seen this year.^[14] Kotaku's Toshi Nakamura also suggested that it is possibly the best live-action manga adaptation he's seen. However, he said the motivational romance between Mashiro and Azuki was "surprisingly inconsequential" and boring.^[15] Mark Schilling for The Japan Times gave the film four out of five stars, with strong praise for director and screenwriter Hitoshi Ōne.^[16]
