Walt Disney Worldis one of the most popular vacation destinations on the planet, and it also served as a setting for two movies that were secretly filmed on theme park property. Guerrilla filmmaking has a long and complicated history, and with Hollywood productions becoming the norm, it has largely faded in favor of a movie made through the proper channels. Filming on location requires a bevvy of permits and is also typically an expensive prospect, because the locations themselves usually demand some sort of compensation for loaning out their space for a movie.
