Factual error: In the scene where Toula removes the 'Computers and Tourism' flyer from the bulletin board, there is another flyer in the top left of the screen advertising the 2001 Class of Ryerson. Ryerson University is located in Toronto, while the movie is supposed to be set in Chicago. (01:11:05)
