Behind this man-made hill
of garbage and sewer sludge is Lake Calumet, an industrial shipping port located
within the limits of the city of Chicago. During the production of the
movie, movie-makers dropped the red Nazi station wagon from 1,000 feet in
the air. The property abutting the Calumet River happened to be owned by the
Chicago Sanitary District and special permission had to be obtained.
Director John Landis has said special permission and air-worthiness tests were also needed from the
FAA because the drop was from so high up.
