- In May 2004, Michael Moore announced that Disney (which owns Miramax, the film's distributor) had officially prohibited Miramax from releasing the film and expressed his frustration that the film was being stifled. Disney said that the decision had been made a year earlier in May 2003 when it told Miramax that it would not be willing to distribute the film. Disney chief executive, 'Michael Eisner' , said that Moore was announcing it at that time to create publicity for the film's screening at the Cannes Film Festival. Moore claimed that Eisner had expressed concern that the film might jeopardize tax breaks granted to Disney for its theme park, hotels, and other ventures in Florida, where Jeb Bush, President George W. Bush's brother, is governor.

- On the first submission to the MPAA, the film received an "R"-rating.

Former New York State governor Mario Cuomo appealed to the MPAA on Moore's behalf to request a "PG-13" rating. The appeal was not successful, and the movie ended up with the current rating of R for "some violent and disturbing images, and for language".
- After its official showing at the 2004 Cannes Film Festival the movie was given what has been called "the longest standing ovation in the history of the festival". Although the exact length of the applause is a matter of debate, journalists at the screening have reported it being in the area of 15 to 25 minutes.
- Moore interviewed American contractor Nicholas Berg, who was later kidnapped and killed by insurgents in Iraq, but removed the interview from the final cut. He said that the interview would not be released to the media and dealt privately with Berg's family.

- Moore decided not to submit the film for consideration for the Best Feature Documentary Oscar because he wanted to attempt to have it broadcast prior to the US Presidential Election on 2 November 2004 and the rules for that Oscar dictate a longer waiting time for an eligible film to be broadcast. In addition, since he already won an Oscar in that category, he felt the above reason took precedence and he might as well let other documentarians have a fair chance at the award. Instead, Moore announced his intention to have his film compete in the Best Picture category which has less strict submission rules.
- Michael Moore states in the film that only one member of Congress has an enlisted son in the Armed Forces. That member is South Dakota senator Tim Johnson, a democrat.
