What they don't know is that they entire stunt has been planned out for over a year and there's no real movie being filmed in order to parody Hollywood and not be mean-spirited toward Riverside. In the end, everyone was let in on the joke and Riverside receives $100,000. The phony Invasion Iowa movie has cast and crew that are both residents of Riverside and hired actors and actresses.
