It is reported that the uncompromising director's subjects have included Presidents John F. Kennedy and Richard Nixon, Alexander the Great and Fidel Castro. And now, he is setting his sights on the present White House incumbent.

Stone, an outspoken critic of the Bush administration's invasion of Iraq, told the media that the film will not be a hatchet job, but "a fair, true portrait of the man," examining areas such as his relationship with his father, President George H.W. Bush, his youth, and conversion to Christianity.

It would tackle questions such as "how did Bush go from an alcoholic to the most powerful figure in the world?" Stone said.

Stone said he is in talks with Josh Brolin, who stars in "No Country For Old Men" and "American Gangster," to play the title role in Bush.

He hoped to start production by April, with a release in time for the election in November or the inauguration of Bush's successor in next January.

"It will contain surprises for Bush supporters and his detractors," Stone said.

Stone won best director Oscars for "Born on the Fourth of July" and "Platoon." He won a screenwriting Oscar for "Midnight Express."
