At Mostly Film, Blake Backlash writes about films “mixing of Hollywood’s Grande Dames with Grand Guignol.”  “Such cinematic mixing of Grande Dames and Grand Guignol had its heyday in the second-half of the sixties, and such films are sometimes (more-or-less) affectionately known as psycho-biddy pictures. They tended to feature an actress over 50 in some sort of peril, a melodramatic plot and a title that ends in a question mark.  But there is another, related tradition that goes back further that I think we could place these films in.” (via Dr. Giallo)
