Clooney denies Bush attack in new film

Hollywood star George Clooney has rubbished claims his latest movie is a veiled attack on US President George Bush - but refuses to apologise for the film's politically sensitive themes.

Syriana - a political thriller focusing on the oil industry - has sparked controversy for its sympathetic portrayal of two Pakistani boys who become suicide bombers, but Clooney is adamant their story must be told.
