"Cursed" as it should have been
The link below is an interview with Craven in which he states he would like to release the footage to student film makers and let them recreate the movie as they see fit. There is no ending of course, but I also would like to see what they originally intended even if it is incomplete. Mostly for the werewolf effects which Rick Baker released some pictures of (second link). I am not sure if these pictures are actual makeup test shots or just artist's renderings of transformation ideas.
