After shooting, Michael Giannantonio had so many ideas left for the film he has written 2 sequels.
When the restaurant worker (John Voight) pees his pants there was actually a huge hose with a nozzle the size of a gas pump in his pants.
The green-screen scene of the man and woman in the car was done with incorrect lighting and almost got cut from the film all together.
A Super Soaker was used to pee on pee on the tray of food and the blue shoes in the scene weren't on anyone's feet, they were moved by hand by a crew member.
