Trey Parker and Matt Stone were set to have a cameo as Arbie's parents, but the scene was scrapped during shooting so the audience never sees the parents. While the movie was still in production, Parker and Stone were often credited for being in the film.
The restaurant scenes were filmed inside an empty McDonalds (you can see the old McDonald's registers and the doors in the restaurant) and everything else was filmed inside an old church that also served as the team's living quarters.
The film made national headlines in 2011 when a man named Sidney Klawitter purchased what he thought was a DVD cleaner, but turned out to be a copy of the movie. Klawitter called the film horrifying and a XXX film. The store owner stated that the device was prepackaged and purchased from a company based in Oakland, CA. No charges were ever filed in the case.
