@deathlock / americangods: It's not "in UK theaters" or on DVD, it just had its world premiere at a UK festival. AFAIK, the actual UK release date has not been set, US theatrical date on IMDB is 9th October 2009.
Self plug: I saw it and have a full review of the festival at www.80sfear.com - my one word verdict of Night Of The Demons - fun.
