Also in the mid-1960s, Francis began an association with Amicus Productions, another studio like Hammer which specialised in horror pictures. Most of the films Francis made for Amicus were anthologies such as "Dr. Terror's House of Horrors" (1965), "Torture Garden" (1968) and "Tales from the Crypt" (1972). He also did two films for the short-lived company Tyburn films. These were "The Ghoul" (1975) and "Legend of the Werewolf" (1975). As a director, Francis was more than competent, and his horror films possessed an undeniable visual flair. However, he regretted that he was seldom able to move beyond genre material as a director. Francis directed the little-seen "Son of Dracula" (1974), starring Harry Nilsson in the title role and Ringo Starr as Merlin the Magician. Of the films Francis directed, one of his favorites was "Mumsy, Nanny, Sonny, and Girly" (1970). "Mumsy..." was a black comedy about an isolated, upper-class family whose relationships and behaviors came equipped with deadly consequences. The film was not very well received by mainstream critics but has gone on to become a minor cult favorite among fans. In 1985, Francis directed "The Doctor and the Devils", based on the crimes of Burke and Hare.
