Did you catch Haloween, right before Nightmare was on? They showed the DVD version with quotes and notes on the bottom about the filming of the movie. VERY COOL obscure facts.
Like:
The budget was only $250,000 and it grossed $55 million. Most of the staff was the director and producers friends, who were unpaid.
The Hadonfield neighborhood scenes were shot in Illinois in the spring and they had to bring in bags of autumn leaves to make it look like October.
John Carpenter not only directed the movie, but composed all of the music by himself.
In one scene you can see smoke from the director’s cigarette cause he was smoking to close to the camera.
etc, etc…
