PAN'S LABYRINTH director Guillermo Del Toro is developing a new movie about fictional apeman TARZAN's upbringing. The celebrated Mexican moviemaker says he has always felt cheated by Tarzan films because they never focus on the jungle hero's childhood. He says, "The idea is to try to do a version unlike any other, in the sense that Tarzan's formative years, growing through the jungle (sic), are incredibly tough and brutal. "There's always this idyllic sense of the jungle being like a Disney set and I want to portray how this guy becomes the toughest animal in the jungle."
