The Saudi royal family, the House of Saud, is at odds with Moore over his claims that the Bush administration secretly smuggled a number of high-profile Saudi nationals out of the US immediately after the 9/11 terrorist attacks in New York and Washington.
Prince Turki al-Faisal, the Saudi Arabian ambassador to London and a half-brother of Crown Prince Abdullah, who was in charge of Saudi intelligence at the time of the attacks, said that Moore failed to carry out adequate research into the controversial claims that there was a link with Saudi-born Al Qa'eda leader, Osama bin Laden.
In an interview with the Daily Telegraph, Turki said that Moore requested a visa to Saudi Arabia, which was granted, but he never went. "He chose to speculate... and missed an important opportunity to find out key facts," he said.
In addition, authorities in Kuwait, a key US ally, also objected to the film's criticism of the American-led invasion of Iraq, which was launched from Kuwait. Abdul-Aziz Bou Dastour, of the Kuwaiti information ministry, claims that there is a law about insulting friendly nations.
The state-owned Kuwait National Cinema Company had applied for a licence to show 'Fahrenheit 9/11', but its request was turned down by government censors. However, it is currently being shown in other Middle Eastern countries, including the United Arab Emirates and the Lebanon.
The documentary, which criticises George Bush for being unprepared for the September 11 attacks, has broken box office records for a documentary, making $100m (£54.5m) in North America. The film also won the Palme D'Or at the Cannes Film Festival.
