I had pretty low expectations about this. These "scholastic" 70's Italian sex comedies are generally the lowest of the low-brow when it comes to comedia all'italia. The director Michele Massimo Tarantini rarely proved himself to be anything but a hack, and the second-billed actor is Alvaro Vitali, an unfunny and often downright irritating buffoon who is once again playing the world's oldest secondary student. The casting is all pretty ludicrous--not only do you have a group of ridiculously overaged students, but their new replacement "science teacher" (after the first one blows herself up in the chem lab) is played by former Miss Italy runner-up and future hardcore porn star Lili Karati, who was all of about nineteen at the time.
Fortunately though, the movie doesn't waste much time with juvenile classroom antics, but goes into the surrounding town for some much more effective provincial comedy. There's a lot of European-style bedroom farce comedy including a priest who's concerned with the town morals and eventually has a revelatory vision where EVERYONE is (literally) wearing horns, and a lonely druggist (Gianfranco D'Angelo who's even goofier looking than Vitali) who falls in love with a sexy but bedridden married woman and has bizarre (but very Italian) fantasies where he pours various foods all over her sumptuous naked body. Vitali even as one of his best scenes--a 70's style martial arts parody where the diminutive comic beats up a whole gang of surly street toughs while reading a how-to book on karate in the middle of the fight.
But speaking of Karati, the very sexy Lili isn't left with a whole lot to do but take off her clothes a lot--something she fortunately does VERY well. She first takes a very long and very hot bath while the juvenile protagonist and his friends watch through the keyhole. Then she casually strips off in her apartment while protagonist and his friends watch from the flat above with a make-shift periscope. Then she almost has sex with the protagonist. Then she finally DOES have sex with the protagonist in a well-filmed scene in the open sea (Tarantini certainly spent a lot more money on this than he did on his subsequent "schoolteacher" comedies). I don't want give away the ending, but it's very Italian (no doubt inspired Salvatore Samperi's classic "Malizia") and very un-American. It also contains the memorable image of a new bride being unzipped and felt up at her wedding party while her new husband is totally oblivious, which may offend both morality and feminism, but is so much more refreshing than the usual racing-to-the-altar-to-stop-the-wedding scene, which as been such a cliché since "The Graduate".
