That entire episode would never have happened in real life. You would think people who write for TV shows would have some idea how movies are made. The New York film company would have shot the film in NYC, not haul the crew, cameras, lights (BTW what are they planning on plugging the lights into?), etc into the middle of nowhere in the Blue Ridge Mountains. Also John is hired to provide lumber for the sets; what sets? And where are they building them, inside the old house? Bollocks.
