The title of the movie caused a legal conflict. There was already a pizzeria in Santa Cruz, CA trademarked "Pizza My Heart". The producers tried "Pizza My Heart, The Movie" That was already trademarked as well. This same pizzeria delivered rental videos with their pizzas. Apparently the conflict was resolved.
The Pizza War scene was filmed in weather of 40 degrees Fahrenheit, although it was supposed to be in the summer; the extras and cast were freezing during the filming.
