JoJo's Bizarre Adventure: Diamond Is Unbreakable - Chapter 1 (ジョジョの奇妙な冒険 ダイヤモンドは砕けない 第一章 JoJo no Kimyō na Bōken: Daiyamondo wa Kudakenai Daiisshō?) is a live-action movie adaptation of Diamond Is Unbreakable of the JoJo's Bizarre Adventure manga series, co-produced by Warner Bros. Japan and Toho. The film will be directed by Takashi Miike. 
It was officially announced on September 28th, 2016, with the film stated to release in August 4th 2017.
In 1999, a mystical Arrow, which can manifest latent Stand abilities, travels throughout Morioh, Japan. A high schooler named Josuke Higashikata and his friends are thrust into a new world they never knew existed, having to face off against deadly Stand users whilst trying to uncover the mysteries of the Arrow itself and how to stop its wielder.
Initial rumors in July 2016 of a movie adaptation of Stardust Crusaders being in production began to circulate only for no official confirmation to validate the authenticity of the claims. Eventually on September 28th 2016, at a panel to promote JoJo's Bizarre Adventure the film was revealed to the public, instead being an adaptation of Diamond is Unbreakable. TBS producer Takashi Hirano explained that the staff decided to adapt the manga's Part 4 storyline since it features a Japanese protagonist in a Japanese setting. He then further clarified that the cosmopolitan nature of the manga offers a chance for Japanese cinema to expand across the world; including actors of a particular Part (such as English or Italian characters) to be played by their appropriate race.
In regards to the film's subtitle of "Chapter I", Hirano explained that due to the complexity in the plot and characters of Part 4 it would be impossible to adapt its entirety into a two-hour film. Hirano then said that if the film is a commercial success, he'd love to adapt the remainder of Part 4 through more films. Director Takashi Miike decided on the Spanish city of Sitges as the shooting location after looking through options worldwide. He acknowledged that the original manga's setting is loosely based on the real Japanese city of Sendai, but determined Sitges was the closest match to Morioh's fictional setting.
- Some of the characters in the film (notably Jotaro and Josuke) have had their costume designs simplified and/or changed when compared to their manga counterparts.
- Jotaro Kujo is a middle-aged man instead of being in his late 20's.
- Yukako Yamagishi's character appears earlier than in the original material.
- Director Takashi Miike revealed that he did not sleep for three days after receiving the offer to direct the film project.
