Greystoke: The Legend of Tarzan Lord of the Apes approaches Edgar Rice Burroughs’ source material very differently from previous adaptations. The movie is far removed from the vintage Johnny Weismuller films from the thirties and forties. There are no white ivory poachers, evil tribesmen or a tree house love nest. Nobody says “Ungawa”. This is a revisionist recounting of the Tarzan legend undertaken in a thoughtful and intelligent fashion. Although relatively faithful to the original stories, there are some major thematic changes. Gone are the period notions of Nietzsche’s Übermensch. The screenplay also reflects contemporary understanding of great ape behaviour and society.
