Continuity mistake: The first shot of Lady liberty walking down the streets and looking down at people is an obvious human face in disguise and makeup. In the close-up shot, it is a mask/miniature that doesn't look like the previous one, but does resemble the real Lady Liberty. This is not due to the statue being animated by ghosts, for the mistake takes place between one shot and another (besides, the statue is animated all the time), but because the FX was achieved combining a human in disguise and a miniature set.Sacha
Other mistake: At the end of the movie you see the Statue of Liberty looking down from the rooftop, and then you don't see it the next time we see the rooftop. Then it's on the ground. How can it move without them controlling it?
