"The Castle of Otranto" is animation/short/documentary based on "The Castle of Otranto", a 1764 novel by Horace Walpole, the first Gothic novel. The novel takes place in Otranto in southern Italy. In Jan Svankmajer's mocumentary, the amateur archaeologist Dr Vozáb has set to prove that the supernatural ghost love story takes place not in Italy but in Otranto Castle near Nachod in Czechoslovakia. The events of the story where the characters step out from the pages of the book and presented in animation, are inter-cut with the interview between the Dr Vozáb who is passionate about his findings that prove his idea and a TV reporter who is skeptical about the whole idea... until the very last shot in the movie.
