This city was one of the filming locations for HBO's 1994 film Blind Justice. In the 2003 dark comedy film Bad Santa, the character of Santa tells a child that Apache Junction is the suburb that most resembles the North Pole. A scene from Jerry Maguire was filmed there as well; Cuba Gooding, Jr.'s character was shooting a commercial with a camel. In Gabriel Iglesias stand up revolution Epsiode 2, Mr. Iglesias uses Apache Junction as representative of a redneck place in a joke about comedy clubs wanting to put a catchy name on a show containing multiple people from the same racial group.
