their uncle is busy burning the other sister; somehow he teleports back home and the evil twin gives him a show. Cut out for American audiences and possibly to maintain continuity, the original scene was aired on public television in the 1980s. Music for the film was devised by the British composer Harry Robinson, who had already produced a soundtrack for The Vampire Lovers. Reception Film critic Leonard Maltin gave the film a passing grade of two and a half stars, calling it "engaging" and "inspired" in its use of the Collinson twins. A.H. Weiler wrote in The New York Times that the Collinson twins made the film interesting, but "The rest of the costumed crew...hardly give Twins of Evil a good name." One year after its release, Robert L. Jerome observed, "The film is done with Hammer's obvious care for details and a sobriety which creates the proper mood of unexpected evil in attractive, tranquil surroundings." In other media A novelisation of the film was written by Shaun Hutson and published by Arrow Publishing in association with Hammer and the Random House Group in 2011, . The book contains an introduction by the film's director, John Hough. The film was adapted into an 18-page comic strip for the January–February 1977 issue of the magazine House of Hammer (vol. 1) #7, published by General Book Distribution. It was drawn by Blas Gallego from a script by Chris Lowder. The cover of the issue featured a painting by Brian Lewis based on imagery from the film.
