Michael Moore is the EP. He did not direct or make an appearance or narration.
Depending on the production, executive producers can choose to exercise a significant amount of creative control over the film. I wouldn't bother with anything that Moore's involved in, he's a proven liar, a huckster, and a generally despicable person.
