Cloverfield's New York
Knocking the heads off statues, blowing up buildings, drooling on the lawn in Central Park ... the monster in Cloverfield is the ultimate tourist from hell. Next thing you know he'll be going up the wrong side of the subway stairs and slowly window shopping on Madison Avenue during pedestrian rush hour. Cloverfield is so jam-packed with real NYC locations, we thought it would be fun to take a tour of the local hot spots visited by the monster and learn a little about their history, architecture, and the way in which the monster smashed them all to hell.
