Only one side of the sheriff's car was emblazoned with the graphics and green stripe to save money. The vehicle was owned by Gary Welbon who portrayed the deputy brandishing a weapon. Welbon had driven by during preproduction and offered his vehicle for rent as the law enforcement car. The local sheriff's department loaned Welbon the lights for his roof.
Montverde, FL town council voted to allow filmmaker Joe Lenders to use the town's name in the movie. The vote was in part due to the positive portrayal of the town, but also due to the financial contributions the film crew brought to the economically challenged town. Filmmaker Lenders insisted that many local resources be used to make the movie. Fuel and food was purchased in town and many local residents were compensated for the use of their property.
