Oliver Stone's biopic of President George W Bush is to show him as a hot-headed, once hard-drinking man whose relationship with his father influences much of his life, including an obsession with Iraq.According to an early screenplay obtained by ABC News, the film, entitled W, will chart the President's journey from troubled alcoholic to world leader. It goes back to the President's drink-sodden misbehaviour at Yale, where at one point he loudly denies he plans to follow his father into politics. At one point he also insults his father as "Mr Perfect, Mr War Hero, Mr F------ God Almighty", after being urged to contact Alcoholics Anonymous. W, which shows how the younger Mr Bush gave up drinking after his 40th birthday and became a born-again Christian, also investigates what Stone sees as his determination to avenge Saddam Hussein's attempt to assassinate his father. When Donald Rumsfeld, then defence secretary, asks: "What's the big deal about Saddam? Bin Laden's the trained ape", Mr Bush responds: "You don't go after the Bushes and get to talk about it. Ya got me?" Stone, a polarising director who has described Mr Bush as "a synthetic person", could face more of the criticism he elicited for his takes on Richard Nixon and John F Kennedy, which some historians saw as full of inaccuracies. But the film, which may come out before November's presidential election, also seeks to capture Mr Bush's inner struggles. At one point he is shown telling the Rev Billy Graham that "there's this darkness that follows me. People say I was born with a silver spoon, but they don't know the burden that carries".
