In 1996, Peter Brook organised a reunion for the cast members for a documentary film called Time Flies . Brook was "curious to know what the years had done to his cast, and what effect the isolated months of filming had had on their lives".  Although none seemed damaged by their time working on the film, Simon Surtees, one of a pair of twin brothers who played Sam and Eric, "put his finger unerringly on the ethical dilemma. The problem is that most of us are not trained artists, so I now believe Peter runs the risk of abandoning us to our fate, just as he did in 1961, when he plucked us from our schools and our homes, put us on the island, then cast us back to live our lives as if nothing would ever change." 
Most heavily criticized was the way in which the filmmakers departed from the novel. For example, Richard Alleva of Crisis Magazine criticized the portrayal of the first assembly on the island, a crucial moment in the book, as "anti-climactic" in the film. He lamented the fact that the conversation that Simon imagines taking place between himself and the pig, or the "Lord of the Flies", yet another of the book's most pivotal moments, was in the movie reduced to only a few moments of Simon staring at the pig. Alleva also criticized what he saw as misrepresentations of Ralph and Jack, believing that the movie downplayed Ralph's imperfections as presented in the book and amplified those of Jack. He said that "In this film, the good boys are too good; the bad boys too quickly bad, and bad in the wrong way."
