Question: What is the date of birth of the director of film Her Private Hell?
Sentence (from "Norman J. Warren"): Along with the films of Pete Walker, Warren's movies are sometimes dubbed "New Wave" British horror, on the basis that they upped the ante in terms of sexual explicitness and gore from that of the Hammer and Amicus productions that dominated the genre in UK cinema up to the early 1970s.
Relevant evidence: No
