Trilogia Macabra

The film's third segment, "Bobby", was later remade as the second segment of Trilogia do Terror II (1996), another horror anthology film that was directed by Dan Curtis just as this film was and the first film in the series, Trilogia de Terror (1975), had been 22 years earlier (with that first film originally released two years before this one).

Despite the fact that the film's second segment, "No Such Thing as a Vampire", takes place in the late Victorian era, quite modern electric light switches can be seen in the interior of the house. While electric lighting does date back to the 1880s, the switches in use at that time looked nothing like the switches seen in this house; toggle light switches (which are seen in the segment) had not been invented yet.
