Baseball has 108 red stitches, while people in Buddhism have 108 kinds of troubles. The title of this film, 108, is a pun, which not only points out the theme of baseball, but also implies that the two protagonists as substitutes are full of troubles.

Qi Teng, Aoi Nakamura, Kengo Kora and Keiho Kosuke Kitajima, who play the main roles, can't play baseball. The director arranged for them to enter the training class of professional baseball teacher Masayuki Ji Ze to learn basic movements three months before shooting. A month and a half later, all the 40 actors of Jingbang High School baseball team arrived, and a new round of baseball special training began. The coach is Tomimo Morimoto, who led a new high school baseball team into the top four in three years. It is said that on the first day of group training, the actors were required to run for three hours, and the legs could not be lifted the next day.

The team training scene in this film was taken on loan from the baseball department of Tiki University. In a training scene, director Yoshitaka Mori didn't shoot with a camera at all. He used three cameras to shoot from different angles for three hours and recorded the initial training scene. (Author: JEUX)
