Continuity mistake: When April's lying on the gurney, just as she's wheeled through the doorway it cuts to the closeup as the nurse turns to block Fin from entering the ER, and behind the nurse we see the gurney still being turned and wheeled into the room, but April has vanished.
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.
