Continuity mistake: At the beginning of the film where Metro Man is addressing Metro City, he asks them if they know what the greatest honour they have given him is. When he asks this he is standing at the edge of a pond. But once he tells them what it is, he is suddenly standing in the middle of the pond.
Suggested correction: If you look at the clip, you do see him at the edge of a pond, however, you also see him walking towards the middle, so it's reasonable that he walked that far that fast.
