Sleazy Video Nasty meeting of Giallo and Nunsploitation
20 June 2006 | by (Beverley Hills, England) – See all my reviews

Killer Nun is a crossover between two of sleaze cinema's most popular subgenres; the graphically titled 'nunsploitation' and the more popular Italian thriller known as Giallo. I can't say I'm very experienced with the former, but I'm a big fan of the latter; and the fact that this film was a part of the Video Nasty list back in the eighties ensured that I had enough reason to see it. As a Video Nasty, this film isn't all that good and is unfortunately one of the more tame entries on the list, and to be honest; I can't see a good reason for banning it, other than the obvious implications of a nun taking it upon herself to begin killing people. As a Giallo, this film isn't all that good either - as there isn't a lot of mystery going on, and the murders aren't too imaginative. However, as a slice of sleaze; this film works a treat! The plot follows a nun who finds herself addicted to morphine after having an operation on a brain tumour. However, this isn't the most dangerous element of her psyche; as the patients at the hospital she works at believe that she is behind a series of murders!

The film clearly knows what its main strengths are, and director Giulio Berruti delights in showing things such as lesbianism and torture to his audience. The idea of one of God's disciples going around murdering people isn't the most original idea ever conceived, but it's well worked as the film always appears to be completely serious and manages to stay away from the comic book styling's of many Giallo, which would ultimately have harmed the film. Cult actress Anita Ekberg takes the lead role and delivers a strong performance, which despite not winning her any plaudits; works well in the context of the movie, and she does carry off the nun look well. Joe Dallesandro joins in the fun, and the rest of the unknown cast are good enough for this sort of film. The lesbian scenes in the movie are well done and actually rather erotic, thereby guaranteed to delight the movie's target audience. The plot is always secondary to the sleaze, and therefore isn't too interesting; but it plays out nicely, and while the ending isn't particularly strong; this is a good example of sleaze cinema and is recommended to the relevant people.
