Above, a poster for Kôkôsei banchô: Bôtate asobi, aka The All-Out Game, the second film in the High School Gang Leader franchise. The movie stars Kimisaburo Onogawa, Kei Wakakura, and Saburo Shindo, but Eiko Yanami stars on the poster. Basically, a high school boxing group comes into conflict with a high school judo club thanks to differences between their two leaders, one of whom is a top student and the other of whom is a moron. When we were in high school smart kids couldn’t fight but maybe Japan is different. This premiered there today in 1970. See two more posters from the series here and here.
In this game everybody gives their all.
