Neil Diamond approved the filmmakers using his music in the film due to how much respect he has for Mike Sardina and Claire Sardina.

While it is true that most radio and TV stations west of the Mississippi River start with a 'K' and those to the east start with a 'W', the dividing line from1912-early 1923 ran north from the Texas-New Mexico border. In 1923, the Mississippi River became the new border. However, there are more than a half-dozen TV and radio stations east of the Mississippi that start with 'K', the most notable being KDKA in Pittsburgh, PA. So, placing the fictional KZWH in Milwaukee would not be an error in geography, just an exception to the rule.
