The Horror of Frankenstein is a 1970 British horror film by Hammer Film Productions that is both a semi-parody and semi-remake of the 1957 film The Curse of Frankenstein, of Hammer's Frankenstein series. It was produced and directed by Jimmy Sangster, starring Ralph Bates, Kate O'Mara, Veronica Carlson and David Prowse as the monster. It was the only film in the Frankenstein series which did not star Peter Cushing. The original music score was composed by Malcolm Williamson.

The Curse of Frankenstein is a 1957 British horror film by Hammer Film Productions, loosely based on the 1818 novel Frankenstein; or, The Modern Prometheus by Mary Shelley. It was Hammer's first colour horror film, and the first of their Frankenstein series. Its worldwide success led to several sequels, and it was also followed by new versions of Dracula (1958) and The Mummy (1959), establishing "Hammer Horror" as a distinctive brand of Gothic cinema.
