Circus of Horrors is a 1960 British horror film directed by Sidney Hayers. It stars Anton Diffring, Yvonne Monlaur, Erika Remberg, Kenneth Griffith, Jane Hylton, Conrad Phillips, Yvonne Romain and Donald Pleasence.
Film critic David Pirie considered it to be the third entry in Anglo-Amalgamated's "Sadian trilogy" in his book A Heritage of Horror (1971), because the films focus on sadism, cruelty and violence (with sexual undertones) as opposed to the supernatural horror of the Hammer films in the same era. The previous films in the trilogy were Horrors of the Black Museum and Peeping Tom, both in 1959. It was released in the US by American International Pictures as a double feature with The Angry Red Planet.
