Continuity mistake: When Vernon is looking in the basement files and Carl walks in, the card in the drawer label holder is tilted and it stays this way for a few shots. When Vernon claims it's a highly sensitive area, the card is now straight, but in the shot after that it is tilted again.
Chosen answer: According to the IMDB, the answer is yes. Both movies used the same two high school locations: Glenbrook North High School, Northbrook, Illinois; and Maine North High School, Des Plaines, Illinois. The director, John Hughes, directed both movies and decided to use the same school. He also uses the name Shermer for the name of the high school in Breakfast Club and for the name of the suburb in which the Bueller's live.
