Controversial film-maker Michael Moore is planning to make a hard-hitting documentary based on US President George W Bush's handling of the Hurricane Katrina rescue operation.

Moore grabbed international acclaim with his scathing 2004 film FAHRENHEIT 9/11, which studied Bush's handling of the September 11th (01) terrorist attacks.

The Oscar winner is now "seriously considering" documenting the catastrophe in America's Gulf Coast region.

He tells the New York Daily News, "There is much to be said and done about the man-made annihilation of New Orleans, caused not by a hurricane but by the very specific decisions made by the Bush administration in the past four and a half years.

"Do not listen to anyone who says we can discuss all this later. No, we can't. Our country is in an immediate state of vulnerability.

"More hurricanes, wars, and other disasters are on the way, and a lazy bunch of self-satisfied lunatics are still running the show."
