Web of the Spider

Web of the Spider (Italian: Nella stretta morsa del ragno) is a 1971 horror film directed by Antonio Margheriti. The film is about the writer Alan Foster (Anthony Franciosa) who accepts a bet from Edgar Allan Poe (Klaus Kinski) and his friend Thomas Blackwood (Enrico Osterman) to stay a night in Blackwood's castle. At the castle, Foster meets Blackwood's sister Elisabeth (Michèle Mercier) and Julia (Karin Field). Foster has sex with Elisabeth and wakes up to find that she was stabbed by someone whose body vanishes, allowing Foster to realize the house is possessed by ghosts. Web of the Spider is a color remake of Margheriti's earlier film Castle of Blood.
