In the 1982 novel "Shoeless Joe" by W.P. Kinsella, the (fictional) main character, Ray Kinsella, goes on a road trip to find the (real) writer J.D. Salinger, author of "Catcher in the Rye," because Salinger had a real-life habit of using the last name "Kinsella" for his characters and Ray wants to find out why. In this show the character of Wade Kinsella is played by Wilson Bethel, whose mother, writer Joyce Maynard, had a very well-publicized relationship with Salinger.
The restaurant at which the characters in Bluebell hang out is called the "Rammer Jammer." This is a reference to a spectators' cheer yelled at University of Alabama football games when Alabama has just won or is clearly about to win. The cheer goes: "Hey, (opposing team)! Hey, (opposing team)! Hey, (opposing team)! We just beat the hell outta you! Rammer Jammer Yellow Hammer Give 'em hell, Alabama!" The term "Rammer-Jammer" came from the title of a 1920s-era student newspaper, while the Yellowhammer is the state bird of Alabama. The shooting location is the same as the one for the restaurant/bar Merlotte's in the HBO series True Blood (2008). There actually is a restaurant called "Rama Jama's" across the street from the University of Alabama football stadium in Tuscaloosa.

In other countries the titles (translated into English) include: "A Choice of the Heart" (Brazil); "The Southern Heart" (Serbia); "Heartland" (Finland); "Doctor in Alabama" (Portugal)"; Doctor of Hearts" (Hungary); "Zoe Hart from the Southern State" (Russia); "Zoe Hart" (french Canadian/Quebec).
