Sister Gertrude, in the 1978 Italian horror film "The Killer Nun," is certainly not your typical, garden-variety nun. Addicted to mainlining morphine (Sister Morphine?!?!) as a result of a recent brain tumor operation, she also smokes cigarettes, drinks liquor in bars, hallucinates, has up-against-the-wall sex with casually picked-up men, wears makeup, steals, engages in domineering lesbian sex with her roommate, and, perhaps most shocking of all, refers to her Mother Superior as "bitch." Still...does that mean she's responsible for the wave of recent murders in the French hospital where she works? What would YOU think? As played by Miss Sweden 1951 herself, Anita Ekberg, Gertrude really is a sight to behold, both in and out of the, er, habit. Sadly, this picture, though great sounding in synopsis, is a real mixed bag, never dishes out quite enough in the sex and violence departments, and will probably leave most viewers wanting more in terms of sleaze, shocks and scares. Still, there are some pleasures to be had here. Giulio Berruti's directing is occasionally quite stylish, and the film's score, by Alessandro Alessandroni, is freaky (especially during Gertrude's "shooting sprees") and really quite excellent. Film buffs will also be happy to see Alida Valli and Joe Dallesandro in small roles, and one of the film's murders, featuring multiple hypodermic needles in an old woman's face, should satisfy all the gorehounds out there. The DVD that I just watched, from the good folks at Blue Underground, looks fine but has been poorly dubbed; subtitles would have been infinitely preferable. I had to watch the film twice to make sure I understood the ending correctly--the hushed, fast-talking dubbing doesn't always make things easy--and, if I may make a, um, confession, did appreciate it more the second time around.
