I never even heard of it until all the controversy came up that Collins must have plagiarized it. Considering it was a book written in Japanese, published in Japan in 1999 and then made into a Japanese movie and manga series in 2000 I am sure everyone in the entire world must have read it and seen the movie.
Thing is I have seen it many times before when several authors all get the same idea and write a story about it. Some of the novels, suck, some are OK some are great.
Battle Royale - Wikipedia, the free encyclopedia
Now that is an author with some sense.Since its release, the novel and its film adaptation have had an influence on later works. These include filmmakers such as Quentin Tarantino, most notably his Kill Bill films; the character Gogo Yubari, played by Chiaki Kuriyama, is similar to the character she plays in the Battle Royale film, Takako Chigusa. V.A. Musetto of the New York Post also compared it to The Condemned, which the critic called "a bad rip-off" of Battle Royale as well as The Most Dangerous Game. Critics have also noted the influence of Battle Royale on other later works, such as the 2008 film Kill Theory, the 2009 film The Tournament, and the novel and film franchise The Hunger Games. Battle Royale has also been compared to the manga, anime and film franchise Gantz, and the 2007 video game The World Ends with You.
The 2008 American young adult novel The Hunger Games by Suzanne Collins has been accused of being strikingly similar to Battle Royale in terms of the basic plot premise and the world within the book. While Collins maintains that she "had never heard of that book until her book was turned in", Susan Dominus of The New York Times reports that "the parallels are striking enough that Collins's work has been savaged on the blogosphere as a baldfaced ripoff," but argued that "there are enough possible sources for the plot line that the two authors might well have hit on the same basic setup independently." The general consensus in the time since has been one of amicable controversy, especially since the release of the The Hunger Games film adaptation. Battle Royale author Takami said he appreciated fans "standing up" for his book, but stated that he thinks "every novel has something to offer," and that if "readers find value in either book, that's all an author can ask for."
