A row has broken out over the distribution of a new documentary film by the award-winning American director, Michael Moore.

The Walt Disney group has banned its subsidiary, Miramax Films, from distributing the film, called ‘Fahrenheit 911’, which criticises the Bush administration's policies before the 11 September attacks in 2001.

Mr Moore’s new film will be premiered at the Cannes Film Festival later this month.

Disney's Chief Executive, Michael Eisner, described the documentary as ‘totally appropriate’ but said the company did not want it released in the middle of a political process in the US.

However, Mr Moore said it would be widely shown, regardless of the ban.
