 GEOG: At the end of the movie, when Duncan and Hallie are going out  for a second date, the camera pull back to show Secret Service SUVs  and a helicopter following Duncans car. The buildings are  skyscrapers, which are much too tall to be Washington DC, as  building codes for the District provide that no building may be  taller than the Capitol, which is only 287.5 feet tall. (The  Washington Monument is the only exception.)
