Moore: 'Gibson quit after White House warnings'

Controversial director Michael Moore claims Mel Gibson backed out of financing his hit documentary Fahrenheit 9/11 after Republican sources told the actor he would never be invited to the White House again.

The explosive Palme D'Or-winning documentary, which examines American President George W Bush's decisions following the 11 September attacks and the run-up to the war in Iraq, was rejected by their original financier Icon, owned by Gibson.
