At one point in the film Bush is seen in the primary school classroom where he first learned of the planes being flown into the World Trade Center towers, and Moore slows the footage down so that Bush is seen to be blinking uncomprehendingly and endlessly, a child's storybook open ridiculously before him, as a counter in the corner of the screen counts out the nine minutes before the President seemed to react.
That's what I had heard about Moore's movie, except for the slowing down thing. But does that tape show his reaction after the first tower being hit, or the second? I'll bet it's the first, and Moore is intellectually dishonest enough to pretend it's the second.
