Trivia

Takashi Miike was so excited when he got an offer to direct the film that he did not sleep for three days.

The film adapts the "Diamond is Unbreakable" storyline from the "Jojo's Bizarre Adventure" comics. This storyline was chosen specifically because of its Japanese-centred location; most other Jojo tales involve foreigners.

This film released on the 30th anniversary of the "Jojo's Bizarre Adventure" saga.

The VFXperts worked with Hirohiko Araki to make the Stands translate well to live-action.

In Koichi's room there is a collection of "Pink Dark Boy" manga comics. In the "Jojo's Bizarre Adventure" saga, Pink Dark Boy was created by the artist Rohan Kishibe, who is based on Jojo creator Hirohiko Araki himself.
