The representation of gender in horror films, particularly depictions of women, has been the subject of critical commentary. Critics and researchers have argued that horror films depict graphically detailed violence, contain erotically or sexually charged situations which verge on becoming pornographic, and focus more on injuring or killing female as opposed to male characters. Many also perceive recurring themes of misfortune for male characters who perform overt masculinity or sexuality. Audience reception is suggested by researchers to be affected by the respective gender representation depicted in these movies. Psycho-biddy is a film subgenre which combines elements of the horror, thriller and woman's film genres. It has also been referred to as Grande Dame Guignol, hagsploitation, and hag horror. Per Peter Shelley, the subgenre combines the concepts of the grande dame and "Grande Guignol". Films in this genre conventionally feature a formerly glamorous older woman who has become mentally unbalanced and terrorizes those around her. The genre is considered by scholars such as Shelley and Tomasz Fisiak to have been launched with the 1962 film What Ever Happened to Baby Jane?. Films in this vein continued to be released through the mid-1970s and per Fisiak, has had an influence on multiple areas including music videos. Renata Adler, in her New York Times review for the 1968 film The Anniversary, referred to the genre as "the Terrifying Older Actress Filicidal Mummy genre." Per Shelley, for a film to fall within the subgenre the movie must use grande guignol effects and have an actress who portrays the lead character as one "with the airs and graces of a grande dame". He further stated that common hallmarks of actresses in the subgenre included those who were "no longer considered leading lady material" or had "previously specialized in supporting roles", and "had not worked for some time". The term and genre have received criticism, particularly in regard to claims that psycho-biddy films exploit actresses who have experienced or are vulnerable to ageism.
