Daniel Drezner has the facts: Michael Moore massages the facts. In fact, it seems Moore just lied to 'improve' his story.
The weird thing is, the original version was a good story too — just not as likely to get headlines. It appears that Moore has a contract with Mirimax, Mirimax wants to distribute the film, Disney won't let it. The difference is that Disney's been consistent on this rather than springing it on Moore.
In other words, Moore manufactured a news hook, and got a lot of headlines. That's pretty shabby. The basic issues — why Disney is against the movie (politics? fear? aesthetic differences?) remain.
I don't think I'll be going to see this movie. But then I didn't go to the last one either.
