Director: Kinji Fukasaku
“Kinji Fukasaku stated that he decided to direct the film because the novel it was adapted from reminded him of his time as a 15-year-old munitions factory worker during World War II. At that time, his class was made to work in a munitions factory. In July 1945, the factory came under artillery fire. The children could not escape so they dived under each other for cover. The surviving members of the class had to dispose of the corpses. At that point, Fukasaku realised that the Japanese government was lying about World War II, and he developed a burning hatred of adults in general that he maintained for a long time afterwards.” – WIKIPEDIA  
Battle Royale is a slasher film set in dystopian Japan where children have stopped bothering to go to school and the youth are out of control. Certain classes are forced to participate in a Battle Royale by the government which is an engineered fight to the death that can result in only one winner.
My opinion is that the director made the film what it is today and had it been executed by anyone else it would not be as entertaining. The morbid humor and slapstick violence add to the shock value of the film whilst making it watchable, if events had been carried out in a serious way I don’t think the film would have been as successful.
The film was a mainstream blockbuster success and has won numerous awards, a full list can be found here.Battle royale is a classic dystopian treasure ,
8 out of 10, a must watch masterpiece.
