Which film is about 30 schoolboys who are marooned on an island?
"Lord of the Flies" is a 1963 British drama film, based on William Golding's novel of the same name about 30 schoolboys who are marooned on an island where the behaviour of the majority degenerates into savagery. It was written and directed by Peter Brook and produced by Lewis M. Allen.
The film was in production for much of 1961, though the film did not premiere until 1963, and was not released in the United Kingdom until 1964. Golding himself supported the film. When Kenneth Tynan was a script editor for Ealing Studios he commissioned a script of "Lord of the Flies" from Nigel Kneale, but Ealing Studios closed in 1959 before it could be produced.
The novel was adapted into a movie for a second time in 1990; the 1963 film is generally considered more faithful to the novel than the 1990 adaptation.
