References in popular culture The little town of Coal City was mentioned in the classic comedy The Blues Brothers. Elwood Blues (as played by Dan Aykroyd) explains that his brother Jake (John Belushi) was in prison for holding up a gas station, and then says "He pulled that job to pay for the band's room service tab from that Kiwanis gig in Coal City." For years residents of Coal City wondered if Aykroyd really said "Coal City" or said "Cal City" (a nickname for Calumet City, a much bigger city in Illinois). However, when watching the DVD of Blues Brothers with subtitles on, the text says "Coal City." The Steve Martin and John Candy comedy, Planes, Trains & Automobiles, was partially filmed in Coal City and other nearby towns. Schools Coal City is served by Unit School District 1.
