any more information?

i really enjoyed this film and was wondering if anyone had any more information about the filming of it?

i found a site that mentioned it was filmed in marlow in bucks but that is all.

like most of fulci's films filmed outside of italy it would have been a minor italian invasion for the people living there and i wonder if anyone remembers it and has any stories about the master himself.

the best way is probably for me to find an old pub in marlow and have a chat to some of the regulars there, but short of making the trip does any one know anything?

cheers.
