三级片：香港剥削电影不为人知的故事 (2018)

Until the end of the nineties, the Hong Kong cinema that explored the limits of sex and violence without shame was labeled "category III". Calum Waddell's new documentary, an exhaustive investigator of the mysteries of genre film, is immersed, through interviews and archival images, in one of the most wild and exciting popular film cycles.
