Flavia the Heretic has been put in with the 'nunsploitation' sub-genre, although personally I'd say it fits in closer with the historical period epic genre. Most of the time when these films say that they're "based on actual events", you have trouble believing it; but that's not the case here, as although I don't know anything about Italy in the 1600's, the film is of a far higher quality than most nunsploitation garbage, so it could well actually be based on a true story. I have to admit I prefer the trashier side of nunsploitation myself; Joe D'Amato's masterpiece "Images in a Convent" being my favourite so far, but this film deserves respect for its classy and bloodthirsty historical portrait. The film focuses on the title character: Flavia. Flavia is a nun at convent that is invaded by a 'Tarantula Sect', and this sect proceeds to insult the nuns and their Christian beliefs by defiling their place of worship. Flavia decides that she cannot take this blasphemy, and flees the convent, with revenge in mind...
The blood, sex and violence in this film actually has more power than that in a lot of similar movies. The whole film is very realistic, and this is a huge benefit to it as this allows director Gianfranco Mingozzi to create a truly macabre and morbid atmosphere. Much of the plot goes towards building up the central character, and this sets Flavia the Heretic apart from many of it's seventies counterparts as it means that the character gets developed in a way that makes sense, and it's clear that the director and everyone involved wanted to make a serious piece of art. Florinda Bolkan is excellent in the title role, and brings some real credibility to the film alongside a good support cast. There are some truly nasty sequences in this film; including many shots of people being spiked, a decapitation, a very realistic 'skinning' scene and plenty of rough sex. But none of this appears out of place as the director ensures that the graphic violence fits with the rest of the film. Overall, I can't call Flavia the Heretic a favourite of mine; but it deserves more respect than a lot of these films do, and it's definitely worth seeing.
