Trivia, insights & behind the scenes
The title references the 2006 demotion of Pluto from planet status — a metaphor for how the school system strips students of their 'full' humanity when they fail to rank.
Shin Su-won, a former teacher, based the film on real competitive Korean high school culture where students' ranks are publicly posted monthly.
