At the 8:55 mark, the Narrator describes "an Invid hive atop the tallest building in the city" as the camera pans up what is clearly the Empire State Building. That famous structure was the city's tallest from 1931 until 1970, when it was surpassed by the North Tower of the World Trade Center, which still stood tall when this program was produced in the 1980s. (As of 2024, the Empire State Building has fallen to eighth place among NYC's tallest buildings.)
