A very cool poster. Looks like it was a very limited run put out by bigscreenboxoffice.com back then.
Back on October 30th & 31st of 2006, John Carpenter's original horror classic HALLOWEEN played in select theaters across the country. Fans that caught those screenings were treated to a short featurette titled HALLOWEEN: THE SHAPE OF HORROR, which featured new interviews with HALLOWEEN alumni Nancy Loomis, PJ Soles and Charles Cyphers, as well as Rob Zombie talking for the first time since he was announced as director about what he was planning to do with his remake of HALLOWEEN. Those 2 nights were the only time fans were able to see this exclusive featurette.
