Other mistake: When Lady Liberty's head rolls down the street behind Ellen, Mora, and Polly, it's a very distinctive street and there's a large white storefront sign 'Aleva' over a green awning that they all pass. Then after they drive off in the truck they're driving down that same street, even from the same direction, with that enormous head still after them. Additionally, that building with the 'Aleva' storefront and its awning has simply vanished the second time around.
