This movie ( i also believe is in the public domain) has a Ghosthouse feel but with lower production values. There is some light nudity but no more than the uncut version of The Guy From Harlem. The story is about a group of teens going to a movie set and discover a haunted movie script which rewrites itself to include the deaths of the characters. The lines are hilariously bad "He's dead, It's in the script!" or something like that and the ghostly killer looks like a big Iron Maiden fan circa 1987
