"Battle Royale" is a japanese cult movie by Kinji Fukasaku released in 2000.
You need to know that two incidents made this a cult classic:
Firstly, director Quentin Tarantino called it the best movie since 1992. Secondly, when in 2012 "The Hunger Games" was released, there has been a huge discussion if "The Hunger Games" has stolen its plot from Battle Royale. And yes, both movies tell the story of a group of underage people having to fight each other until only one remains.
But still, both movies have a completely different way of storytelling. While "The Hunger Games" focused on its female leading role only, Battle Royale, still having his protagonists, tells the stories of nearly all of the side characters, too. There are no unnecessary deaths or characters. Every character deals with the situation in a unique way. Some commit suicide, some burst out in psychopathic killing sprees, some take revenge on characters that bullied them in the past, some form small groups, etc.
Even if a character we only knew a few seconds dies, we still learn some of his emotions, or his past.
Also, the movie's three protagonists are very interesting. Two of them (one played by "Death Note"-star Tatsuya Fujiwara) refuse using violence, and a third one, who already fought in another Battle Royale, kind of tries to prevent them from harm. They stand together, even if they know that only one can survive. Also, the screenplay is perfectly written, the movie is perfectly filmed.
The movie has lots to think about - what would you do in such a situation? Which character acted like you would?
Overall, "Battle Royale" seems like a more thoughtful, mature version of the already really good movie "The Hunger Games" (4/5 stars), and is one of the best movies ever released.
(SPOILERS may follow:)
The movie's is extremely violent. The brutality caused an 18 rating in almost every country and in Germany and Singapor, it was banned. Almost all of the violence is bloody and brutal, even though it is not a splatter movie. The movie's plot can be unsettling, but the movie itself is not disturbing. It is impossible to write down everything, here are the worst scenes:
A character's collar explodes and there is a graphic wound on his neck, and blood fountains out in a way we know it from Tarantino's "Kill Bill".
A character has an axe stuck in the back of his head (it was an accident).
A character has a knife rammed into his testicles and is then repeatenly stabbed. After being poisoned, a girl vomits blood. A man is decapitated (the decapitation is off-screen, his head is revealed then). A girl's throat is slit with a sense and blood is seen spraying out. A girl has a knife thrown onto her forehead (no blood).
We see several bloody corpses. Several people are shot in a bloody way.
The violence is frequent, but necessary in order to show how gruesome this game is. The violence is not disturbing, but bloody.
There is R-language. Mature elements includes pedophilia, but there is no sex or nudity in this movie.
(END OF SPOILERS)
I rate this "NOT FOR KIDS", but I think mature viewers, 15-17 can handle this. But not all of them.
