In the 2006 comedy movie “Talladega Nights: The Ballad of Ricky Bobby,” Mr. Bobby (played by Will Ferrell) and fellow race car driver Cal Naughton Jr. (John C. Reilly) argue that pizza and chimichangas are examples of cuisine originating in the United States. They were wrong about pizza, which originated in Italy, but some people claim chimichangas, while served in Mexican restaurants, originated in Tucson, Ariz. The scene lends credence to how well Americans integrate foods and flavors from all parts of the globe.
